37 Femtocell deployments in 23 countries

Growing number of operators are committing to LTE small cell deployments which are expected to form a key market trend in 2012, said a recent Informa Telecoms & Media femtocell market status report.

There are currently 37 commercial deployments with regional US operator, Mosaic Telecom, being the latest to deploy femtocells. Telecom Italia announced its plans to launch before the end of the year and SK Telecom revealed it is set to launch the world’s first LTE femtocell service. Furthermore, Telefonica O2 has disclosed pre-launch details of its ‘Boostbox’ femtocell service in the UK for both consumers and enterprises. Separately, a number of deployed operators have passed 100,000 units, demonstrating the scalability and mass-market appeal of the technology.

Over the past quarter, Sprint, the first operator to deploy femtocells, announced it has rolled out 500,000 units and expects to exceed 1 million by 2013. With AT&T constituting the world’s largest femtocell deployment, it is clear that the US continues to be the most mature small cell market. However, several European and Asian operators including Vodafone UK, Japan’s Softbank and France’s SFR, announced they reached scale by surpassing 100,000 deployed units. Vodafone, which recently launched a marketing campaign around its UK femtocell offering, now offers femtocells in 12 countries and plans to deploy across the whole group.

Vodafone UK recently announced it is to offer public access rural femtocells that will be placed on BT telephone poles in order to bring coverage to “not spots” and areas where traditional base stations have not been economical. The report also highlights growing operator commitment to LTE femtocells with Verizon and Sprint announcing support in the past quarter and SK Telecom promising a commercial deployment before the end of the year. A previous survey conducted by Informa Telecoms & Media showed that 60% of operators believe small cells will be more important than macrocells in LTE networks.

CDMA operators continue to aggressively deploy femtocells with both Sprint and Verizon launching enterprise services which allow several femtocells to be linked together to cover large buildings. To assist CDMA operators, the Femto Forum and 3GPP2 recently published an operator guide detailing best practice for deployments.

There are now 37 femtocell deployments spanning 23 countries and 15 further operator commitments. In June 2011, Informa Telecoms Media estimated that there were in excess of 2.3 million femtocells active both privately in homes and offices, as well as publically in metropolitan and rural environments. As such, there are more 3G femtocells than conventional 3G base stations globally and Informa forecasts growth to continue with 48 million access points in use globally by 2014. Eight of the top 10 mobile operator groups (by revenue) offer femtocell services – this includes AT&T Group, France Telecom Group, NTT DOCOMO Group, Sprint, Telefonica Group, Deutsche Telecom Group, Verizon Wireless and Vodafone Group.

Airtel likely to contract multiple vendors for LTE deployment?

Indian service provider Bharti Airtel is close on signing LTE deals for offering 4G services in four circles. Airtel is rumored be ready to offer contracts to four different vendors for each of the circle.

While ZTE and Huawei are frontrunners for bagging the contract in Kolkata and Karnataka , respectively, Ericsson and Nokia Siemens could get the deal for Punjab and Maharashtra respectively. Though none of the players confirmed the deal, insiders said that talks had reached advanced stage.

Bharti had won broadband spectrum in the four circles for Rs 3,314 crore during the auctions held last year. Reliance Industries, Qualcomm, Tikona, Augere and Aircel are the players which have broadband spectrum in various circles but none of them have started services.

Augere, which has spectrum in Madhya Pradesh circle, has announced a deal with Ericsson for equipment supply and launch of services by second quarter of 2012.

Network Sharing in LTE

3GPP network sharing architecture allows different core network operators to connect to a shared radio access network. The operators do not only share the radio network elements, but may also share the radio resources themselves.

Network-sharing scenario allows operators without a UMTS/ LTE license to share the network and supply its customers with 3G/4G services. For example, a 2G operator may supply its subscribers with 3G/4G services using another operator’s allocated spectrum.

3GPP has identified two architectures for network sharing. In both architectures, the radio access network is shared.

In first architecture evolved packet core network element MME is also shared in addition of radio access network (E-UTRAN). This configuration is referred to as a Gateway Core Network (GWCN) configuration.

In second architecture only radio access network (E-UTRAN) is shared and is referred as the Multi-Operator Core Network (MOCN) configuration.

The UE behavior in both of these configurations is same. No information concerning the configuration of a shared network is indicated to the UE.

If the E-UTRAN is shared by multiple operators, the system information broadcasted in each shared cell contains the PLMN-id of each operator (up to 6) and a single tracking area code (TAC) valid within all the PLMNs sharing the radio access network resources.

Based on system broadcasts UE selects desired PLMN and reports it to eNB during RRC connection setup. eNB includes the selected PLMN is in the INITIAL UE MESSAGE message while sending it to MME. The MME indicates the selected core network operator PLMN-id to the UE in the GUTI during initial attach procedure.

Achieving Capital and Spectral Efficiency Beyond 4G Standards

The industry has come a long way towards developing the new platform for ICT communications:
Pre-4G networks that have demonstrated significant performance and capital efficiency improvements over 3G networks have been deployed.
The IMT-Advanced standards frameworks have been approved – LTE-Advanced and 802.16m, WiMAX 2, based on MIMO-OFDMA.
The preparation for widespread use of SDWN (Smart Distributed WBB Networks) technologies has taken place in the standards and early commercial implementations of SONs and distributed architecture deployments.

What differentiates 4G and beyond from prior network technologies is the use of frequency domain technologies that enable a new pathway for organization of networks. This will improve bandwidth density performance by a factor of up to ten times the level of 3G. It is good to witness the advanced MIMO-AAS, multi-carrier and architecture methods being pursued broadly across the industry: 802.16m, 3GPP Rel 10 LTE-Advanced and 802.11ac as well.

What confounds these efforts, particularly for 802.11 and 802.16, is gaining access to spectrum of sufficient BW and quality. The mobile industry has gained more access to spectrum and capital with which to deliver the vision of 4G networks. However, a significant contributor to the success of current wireless networks and devices is the off-load capability of 802.11 Wi-Fi.

The huge success of the mobile phone industry and need for access to licensed spectrum and capital to build nationwide managed networks has led to consolidation in the hands of a few operators in most parts of the world. The situation in the US shows that despite efforts by the FCC to set rules on licensing and encourage smaller operators and aggregations, spectrum has nonetheless been acquired in the initial auctions or later consolidated by the top four operators. This may soon be reduced to the top three as a result of AT&T's acquisition of T-Mobile.

This has raised a high level of concern and should instigate some fresh thinking regarding how to go about making spectrum available in the most efficient and thorough way, while increasingly innovation and broad economic opportunity.

Incumbents Strongly Argue the Case for Licensed Network Dominance

Operators argue that their control over spectrum has resulted in widespread use and industry development. The role of consolidated licensed operators has been necessary to assemble the skills, organized operation, and the several tens of billions of dollars of capital needed for large-scale deployments. Furthermore, past auction results show that small or localized operators have not developed the critical mass needed to deliver similar levels of products and services. Large national operators are needed to deliver the broad fabric of increasingly complex services that will be developed on the 4G ICT platform.

On the other hand, practical experience and detailed studies show that while mobile networks occupy the majority of available spectrum, the results in terms of both utilization of capital and spectrum has been sub-par compared to Wi-Fi. This is, perhaps, a startling claim: mobile/ICT networks and Wi-Fi are very different types of networks. Nonetheless, Wi-Fi has come to be almost universally adopted because it has proven of great benefit.

Considering that Wi-Fi has been allocated a band of global spectrum that has been called 'junk spectrum' because it falls in with use of portable phones, microwave ovens, and other interferers, and studies show that managed spectrum access is technically more efficient (less signaling overhead than collision based MACs), Wi-Fi has delivered incredible performance. The simplified reasons for this are: 1) the cost of installing Wi-Fi is low due to low equipment cost and low-cost deployment. 2) The use is naturally organized on a microcell architecture that makes extended reuse of the spectrum. 3) Management and maintenance costs are low compared to large-scale networks despite their size advantage. It can be argued that some costs of Wi-Fi are hidden: people may spend considerable personal/company time that is ignored in a comparison. However, costs are significantly counter-balanced by the similar time spent for 3G-4G.

Wi-Fi also stands out in efficiency of spectrum utilization, particularly when measured on a bit/Hz/area saturation/time duty cycle basis. Studies in the US by the FCC as well as overseas demonstrate that Wi-Fi achieves 2X-5X better utilization of spectrum. What makes this even more remarkable is that the spectrum used is 2.4GHz: while good for implementing MIMO and having high reuse factors due to limited penetration of signals and range, the use is conflicted by short range, signal loss due to foliage, precipitation, and low power limits.

Technology advancements will help to achieve higher bandwidth throughput, extended range/multi-hop range, and self-organized and ‘smart networking’ capabilities that increase the range of applications for Wi-Fi and 4G network technologies.

While we appreciate the benefits delivered to operators and users by Wi-Fi, we think the industry can go beyond that in the use of paired licensed-unlicensed network technologies using specifically allocated spectrum and clear rules.

What we hope to see is more spectrum to be ordained by regulators for unlicensed/quasi-unlicensed use. What makes the most sense is for a new paradigm of spectrum licensing to develop: co-allocation and development of joint licensed and unlicensed bands. A crude but effective precedent for this is the harnessing of Wi-Fi as the low cost, prolific, and easiest way operators have found to offload the tremendous ramp in broadband demand. If only regulators and industry would plan for similar availability of spectrum and development with the unlicensed portion serving longer range, say up to 2-5 kilometers in normal operation, this would address problems we now face in rural access, achieving world-competitive rates and bandwidths, and stimulating high level of innovation. This would assure a higher level of competition and openness of access with less need to for detailed regulation and policing. The licensed portion of spectrum could be allowed to use aggressive QoS mechanisms and higher specialization needed to fulfill needs of vertical markets and applications while the quasi-unlicensed portion can be commercially ‘self-organized,’ with fundamental open access as the frontier for new stakeholders.

The development of framework technologies for use dual-MAC networks and devices has come far enough to make this a near-term possibility under enhanced LTE-Advanced and WiMAX 2 standards.

The benefit of this approach has more to do with the harnessing of business and user models than technology. The technology is here. While we face many opportunities, government regulators and the industry must figure out the best way to further all segments of ICT industries, and fan the flames capital and spectrum efficiency that are foundational to US and worldwide prosperity and ecology.

17.25 million BWA/WiMAX and 320 thousand LTE subscribers reached in Q1 2011

3.7 million new BWA/WiMAX subscribers were added in Q4 2010, and 5.5 million will be added throughout 2011, according to the 14th issue of the 4GCounts Quarterly Report from Maravedis. The subscriber base for WiMAX and LTE reached 17.25 million and 320,000 respectively at the end of March 2011. The WiMAX subscriber increase represents a 32.7% jump quarter-over-quarter, from 13 million reported at the end of Q4 2010.

Maravedis anticipates that 59 FDD-LTE and 3 LTE TDD networks will be operational worldwide by the end of this year. “There will be 305 million LTE subscribers by 2016, of which 14%, or 44 million, will be TD-LTE users and the rest (86%, or 261 million) will be FDD-LTE,” said Esteban Monturus, co-author of the quarterly report.

TD-LTE has gained global momentum and attracted attention to TDD spectrum. Maravedis anticipates that commercial TD-LTE networks could begin in more than 10 countries or areas in 2011-2012, even ahead of China Mobile's deployment. On the regulatory side, additional spectrum made available for 4G has seen much more progress in GSM refarming than in the digital dividend initiative. The latter is still many years away from full availability.

One of the most notable events that took place during the first quarter of 2011 in Europe was the Swedish 800 MHz band auction in March 2011. TeliaSonera, Net4Mobility and Hutchison 3G each won 2X10MHz of spectrum in the 800MHz for 4G network deployment. The UK´s telecom regulator announced an incoming spectrum auction, which is expected to pave the way for 4G services in the country. According to the proposed details, the auction will be for the 800 MHz and 2.6 GHz bands.

Handsets are surpassing fixed modems and USB dongles. These three are the preferred devices among the top 50 WiMAX operators, representing the 34%, 25% and 30% of the device market share respectively. Handsets and smartphones are taking off thanks to the aggressive deployment of these devices by Clearwire (USA), Yota (Russia) and Korea Telecom (South Korea). We believe that tablets and flip phones that convert into tablets will be the next wave for 2011 in terms of devices.

Applications and devices are driving the use of mobile broadband and consequently increasing the mobile traffic. Mobile video today accounts for 40% of mobile traffic worldwide, and will become the dominant feature of the mobile web. 3D video will become a popular application for mobile broadband, since portable devices allow end users to watch 3D content without uncomfortable glasses. There will be approximately 450 billion mobile video users globally by 2014. In this latest quarterly report we will analyze the alternatives 4G operators have for traffic offloading including using new spectrum, adding more cell sites, deploying new technologies, offloading data onto other networks, and introducing tiered pricing plans.

Russia: Uni-LTEd We Stand… For Now

As predicted in 4G Digest’s January 12th edition, 2011 is going to be an important year for LTE in Russia. Although at that time we were not able to predict which operator would be the first to deploy the technology in the country, things have become much clearer just two months later. The origin of this dramatic change is in Yota’s announcement last week of a US$2 billion plan to build an LTE network covering more than 70 million Russians in 180 cities by 2014.

Given the difficult relationship Yota has had with Roskomnadzor, the Russian spectrum regulator, during the last few months, the operator’s intentions would not have had much relevance if they were not accompanied by a partnership agreement with four telecoms giants in Russia – the Big Three (Vimpelcom, MegaFon and MTS) plus long-distance state-owned Rostelecom. These operators will be granted MVNO operations on Yota’s LTE deployment and will be offered the opportunity to acquire up to a 20% stake in Yota.

Based on the list of companies participating in the agreement, we can assume it is closely related to the 4G research group created under the auspices of Roskomnadzor by the 3+1 operators in January this year. The initial focus of the group was to study the refarming of 710 - 860 MHz spectrum to shift its usage from military applications to civil LTE. Since the Ministry of Communications wants future LTE licensees to pay for the new military equipment operating in alternative spectrum bands, only national operators are welcome to the group. That is why Swedish group Tele2 was not included, despite having expressed interest in joining. The Ministry’s recommendation to Tele2 was to achieve sharing agreements with national operators, but Yota’s announcement clarifies that Tele2 will not even have such a chance for the moment.

The Russian government’s legitimate desire to boost its national industry with carefully tailored LTE deployment affects not only operators, but also equipment manufacturers. One year ago the first signs were envisaged when Rostelecom won 2.3 GHz permits under the premises of using Russian-manufactured equipment. In September, CEO of Russian Technologies (Rostekhnologii) State Corporation (owner of 25% stake in Yota), Sergei Chemezov, introduced to President Medvedev a new dual-screened 4G smartphone that would be produced initially in Taiwan and eventually in Russia. Companies potentially benefiting from this policy include equipment manufacturer Sitronics, which also owns microwave vendor Intracom Telecom and Infinet Wireless.

The spectrum situation is perhaps the least clear issue relating to the aforementioned deal. On one side we have Yota, whose 2.5 GHz spectrum permits where reduced by Roskomnadzor after considering them unfairly allocated. Although its permits are TDD, Yota has always made clear it is focusing on FDD LTE. Besides the network sharing agreement with Yota, Rostelecom also owns permits in the 2.3 GHz band. Osnova Telekom, partially owned by the Ministry of Defense, is conducting LTE trials to determine whether both civil and military networks can simultaneously operate in the 2.3 GHz band. Provided that the 710-860 MHz band is already being considered for transfer to civilian applications (although not officially included in Yota’s plans) and a unified national LTE infrastructure is enforced, it seems that the 2.3 GHz band will in fact be reserved for military applications.

Building a single wholesale infrastructure seems a good strategy for developing countries to efficiently reduce the digital divide, since it reduces coverage overlaps among operators and concentrates investment in expanding coverage and adding capacity only where needed. Besides the Russian case, in September 2010 the Kenyan government already published its plans to allow for a single national LTE operator that would offer wholesale services to the 19 operators willing to offer mobile broadband services. This model spurs service and user experience differentiation among operators, thus avoiding the risk envisioned by operators in developed countries of becoming dumb pipes. It will be interesting to see how well both unified wholesale and multiple-infrastructure alternatives cope with the increasing data demand in the coming years.

The Coexistence of 4G Titans

Wireless has now evolved to a more common and overlapping set of technologies and markets such that former distinctions between wireless and wired, streams of standards development including 3GPP and IEEE, and device and infrastructure markets have blurred. Today it is no longer a matter of deciding whether the major industry groups and constituent players should collaborate, but rather how coexistence is efficiently and pragmatically accomplished.

Much work has been taking place within the International Telecommunications Union (ITU), IEEE 802.16e/m, and 3GPP to develop standards for harmonious spectrum access, core network interoperability, backward compatibility, and ease of network and device migration. This work is driven by operators who wish to see a long life for their investments in networks and markets and with suppliers who wish to fulfill the evolving needs of their customers.

This article summarizes a snapshot of current progress:

  • Baseband and integrated chip suppliers have made progress in supplying commercially available ICs and board level products that combine WiMAX and LTE.

- Broadcom/Beceem has shown an integrated SoC (BCS500) and USB reference design board-level unit.

- Other vendors say they will meet needs of the market with dual-mode capabilities as needed. Sequans was the first supplier of commercial TD-LTE device chipsets and say they are well prepared to meet demands for 4G converged solutions.

  • RF antennas and ICs can accommodate the additional modes needed to combine WiMAX and LTE. Suppliers and operators are now dealing with device and network requirements needed to provide service across 3G, WiMAX, LTE, Wi-Fi, Bluetooth, and GPS. Although the growing number of spectrum bands and modes of operation impose increased complexity, WiMAX’s similarity to LTE, including use of harmonious or proximity bands, makes coexistence very doable.
  • The standards groups and individual participants have the methods needed to align signaling frame structures between WiMAX 1, WiMAX 2, 3G-LTE and LTE-Advanced networks. Performance trade-offs for frame synchronization are a less than 10% hit.
  • The markets have evolved to demand IP-based broadband irrespective of underlying network technology.
  • As 3G core networks have converted to IP, the means to converge more easily with WiMAX has progressed. Obviously, the ease of convergence of operators’ networks with LTE or WiMAX depends on the state of their IP network migration.
  • Similarly, subscriber provisioning and billing can be common between WiMAX and LTE. However, incumbent operators must migrate existing networks, if they are not doing so already.

The WiMAX supply ecosystem has evolved to lead LTE development as MIMO-OFDMA technology has emerged to take center stage. As WiMAX has become more mainstream it has entered into more direct competition with traditional streams of development. The broader market opportunities have led to early rounds of consolidation, such as Beceem’s acquisition by Broadcom and participation in early LTE product markets, such as Sequan’s participation with China Mobile.

An effort is underway by leading WiMAX and LTE suppliers and operators to provide a common framework for 4G coexistence. The work covers both technical and practical aspects of convergence of spectrum plans, networks and baseline service provisioning to accommodate a range of operator needs for integration and coexistence of operations. Companies include Broadcom/Beceem, Clearwire, Huawei, Intel, Samsung, Alvarion, Bridgewater, Cedarcom-Mobi, Comcast, GCT, Motorola, Packet One, Sequans, Tellabs/WiChorus, Vee Time, VITI, Yota, and ZTE. Additional companies have worked on similar alignment efforts, including Nokia, Ericsson, picoChip, and Alcatel-Lucent.

The need for operators to find common markets for devices and services that span across 3G, LTE and WiMAX deployments helps to create opportunities that propel development of the commercial products that are now making their way into the market.

It is appropriate to point out that new network deployments, no matter who the operators or suppliers may be, must consider the objectives of reaching common device and market development. The factors of market development often take precedent over the choice of which standard is “winning” the race to become the most ubiquitous way forward. The “best” standard is that which best suits the needs of the operator. This can hinge on maturity and cost of the solution, so long as the evolution of network, devices and market are manageable.

What We Think:

We acknowledge that LTE is destined to become the dominant standard for mobile networks. However, the similarities between LTE and WiMAX are due much to WiMAX’s pioneering efforts to establish and propel OFDMA as the future for wireless technologies. Moreover, convergence is made feasible due to the enabling of IC and wireless component technologies. Decisions regarding which modes or multiple carrier capabilities to integrate into a common SoC or variety of SDR architectural design approaches are often secondary to questions about developing common spectrum plans and practical aspects of deployments required to build substantial market footprints.

Operators now deploying LTE must often deal with more pressing difficulties than combining WiMAX and LTE operation: how and when to migrate device markets to multi-mode capabilities; whether to move now to 3G-LTE or wait for LTE-Advanced; how to incorporate IP-based services including VoIP/VoLTE and video services without sacrificing current revenues on the altar of next generation progress.

We believe that WiMAX and LTE will evolve, as expected, into a growing common market for 4G products and services. While LTE will dominate, WiMAX provides the pedigree of experience and common technology and product development that many suppliers and operators are carrying forward successfully.

Although the leading 3G supplier can be expected to consolidate markets, including the ongoing push toward integrated services, unique opportunities will unfold for companies willing to adapt to mainstream trends. Recent moves by suppliers to provide a pathway to operators for service and supply migration and coexistence heralds inevitable 4G convergence in technologies, products, deployments, and markets.

Update: LTE in Latin America

Latin America is the quietest region in terms of LTE deployments and operator commitments. Other regions such as Europe and Asia Pacific have shown much more LTE activity, accounting for 35% and 26% of the 145 LTE commitments registered worldwide in 2010. Latin America accounted for just 7% of the worldwide share, with 10 operator commitments and 7 LTE trials conducted during the year.

However, more and more Latin American operators are eager to take advantage of LTE’s promises of higher speeds, increased network capacity and more efficient spectrum use. Even regulators in countries such as Chile, Venezuela and Brazil are planning to allocate both residual 3G spectrum and new spectrum specifically for LTE. Maravedis estimates that by the end of 2011 there will be more than 20 LTE commitments in the region, an additional 7 LTE trials will be conducted, and possibly 4 operators will have commercially launched the technology, however the real momentum is expected to occur in 2014-2015, when we anticipate more than 25 operators will have commercial LTE services.

The first LTE operator activity in Latin America started in 2009 in Chile, where Entel conducted trials with Ericsson, Movistar with Nokia Siemens, and Claro, whose equipment vendor was not announced. Entel already offers WiMAX in the 3.5GHz band, but uses it to complement its fixed line service. The three companies are interested in LTE and have conducted trials actively, but they face a big hurdle, which is the lack of spectrum and spectrum caps imposed by SUBTEL to participate in the upcoming spectrum auctions. SUBTEL has ruled that existing players could participate in the upcoming auctions of 700MHz and 2.6GHz in July 2011, but if any operator surpasses the limit of 60MHz it would be obliged to return some spectrum to the state. Entel PCS already has 60MHz in the 800MHz and 1.9GHz combined, while Movistar and Claro have 55MHz each. SUBTEL is planning to auction the 2600Mhz band to make a 140MHz portion (70MHz for upload and 70MHz for download) available for 4G services, meaning that up to four operators could acquire LTE spectrum (35MHz each). Entel is looking to launch LTE in the 700MHz band, however whether SUBTEL will allow existing operators to obtain additional spectrum on top of the 60MHz they already have remains uncertain.

In Brazil, LTE trials have been conducted by Telefonica. Brazilian regulator Anatel decided late last year to re-farm the 2.6GHz spectrum, currently allocated to MMDS operators, and to re-allocate it under a technology neutral scheme to support next-generation mobile broadband deployments. Under the new regulation, MMDS operators will operate in the entire 2,500-2,690MHz frequency until June 30, 2013. After that, part of the 2.5GHz spectrum will be re-farmed and they will keep only 50MHz. The spectrum will be auctioned off by 2012 for the provision of mobile broadband services. 120MHz will be allocated in this auction, however winning bidders are not expected to deploy until 2013 once the spectrum is freed from MMDS operators. Certainly Telefonica will be among the LTE pioneers in Latin America. We believe that its LTE deployment in Brazil could be earlier than 2013, since the operator already holds MMDS spectrum that it can free up for LTE deployment.

Trials have also been conducted in Argentina and Colombia. In the former, Personal has conducted LTE trials with Ericsson and Huawei last year, and Telefonica conducted trials with NEC. These were conducted in the 1.7GHz and 2.1GHz spectrum bands, reaching transmitting speeds of 50Mbps downlink in a 20MHz channel. In Colombia, UNE Telecommunications is eager to start a commercial launch of LTE. CTO Hector Perez recently expressed the company’s interest in LTE to Maravedis. They have been deploying WiMAX since 2006 in the 3.5GHz band and have over 60,000 subscribers, however, Perez said the future of UNE Telecomunicaciones lies with LTE, technology that they will pursue aggressively and will be deployed in their recently allocated 2.6GHz band, in which they obtained 50MHz.

There is clear evidence of Latin American operator interest in LTE, however how the exact number of players and the timeframe in which they will deploy the technology depend heavily on spectrum availability, and the removal of spectrum caps and other restrictions some national regulators have implemented.

2011 Predictions

Before we offer predictions for the coming year, it is worthwhile to take a look at how our forecasts for the current year have worked out.

Trend #1 Device innovations will increase.

2010 was indeed a year of accelerated device innovation:

  • Sprint introduced the HTC EVO 4G, which upped the competition between Android and Apple’s iPhone.
  • Motorola increased their success in Droid-branded Android WebPhones, winning back some of the market share lost to Apple during the previous three years.
  • Apple came out with the improved ‘4G’ iPhone, iPad, and iPods including more efficient batteries, higher resolution screens and camera/video.
  • Samsung upped the ante in display-driven features with Vibrant, Captivate, Epic phone models.
  • Dell, Samsung, Apple, and a flurry or other competitors increased offerings in pad devices.
  • Google announced their foray into pad and laptop OS markets with the official introduction of Chrome. While slated for market impact in 2011, Chrome rides on the coattails of success for Android based pad devices.

Trend #2 Applications stores proliferate to the point of market confusion.

Verizon, China Mobile, and Google Chrome were among the many examples of operators and market makers who made enhanced efforts to establish online mobile applications stores. Several European operators announced efforts to push back against the dominance of Apple and Google in terms of applications and mobile services.

Trend #3 US government broadband spending will lift small boats.

While temporary, US government spending helped keep smaller BWA equipment suppliers afloat during a year of increased competition with mainstream operators and suppliers.

Trend #4 Cloud 4G (cloud computing/ICT) will take center stage as a major theme for wireless operators.

“Cloud 4G” has increased in visibility but cannot yet be said to be a stand-alone market driver. The market remains focused on devices and building out networks needed to position Cloud 4G as an increasingly pivotal aspect of operators’ revenue models.

Trend #5 Clearwire-Sprint will meet their goals of coverage of over 100 million POPs by year end.

Done.

Trend #6 Clearwire-Sprint and their cable partners will move into a more competitive position vis-a-vis mobile operators in ‘hot’ device availability.

Only partially the case: while Sprint and Clearwire benefitted from new devices, particularly the EVO 4G, raising the stature of the WiMAX ‘4G’ network, revenue growth was not up to the level required to stave off the need for an additional capital infusion, nor was raising such funds an easy matter.

Trend #7 Legal battles between mobile device, PC and consumer electronics suppliers will continue.

And so they did: Apple and Nokia expanded their legal and trade battles to include a broader scope of patents and jurisdictions. Wi-LAN, Interdigital, Intel, Qualcomm, Ericsson, Nokia, Samsung, Huawei, Microsoft, and ZTE were among companies pursuing increased visibility for patent positions in 3.5G and 4G wireless, devices and IP networking. In addition, consortia have formed to commercialize IPR and bring forward products in Asia and India, and to continue the shift toward patent pooling.

Trend #8 Verizon will not officially open their LTE network until late 2010.

Verizon chose to launch its LTE network with data only, slating the launch of mobile devices for the 1st half of 2011. We have learned that VZW will show off several devices in Janurary at CES – some due for launch as early as January.

Trend #9 Verizon and AT&T will continue to do battle over coverage and devices.

Indeed, the marketing tempo has picked up speed as Verizon prepares to launch LTE. Expectations for iPhone and iPad availability from VZW have increased, with a Verizon Apple iPad anticipated in the first quarter of 2011. Meanwhile, AT&T has increased the number of Android and new Windows mobile 7 based devices. Complimenting this trend, AT&T will acquire Qualcomm’s 700 MHz spectrum for US$1.9 billion, giving the company a broader coverage map to contend with coverage leader Verizon.

And now, here are the trends we are predicting for 2011:

Trend #1 Pads will proliferate and diversify.

The mobile device market will continue to see increased competition among WebPhones, partially masking the emergence of a more capable and diversified field of tablets/pads and ‘transformer’ devices that covers the span between notebooks and smartphones. This trend will be driven by the growing functionality of combined devices and services; more powerful performance yet longer battery life combined with the thirst for higher bandwidth applications will enable market growth.

Trend #2 Emergence of multiple device attachment.

Although it has been part of the justification for HSPA/HSPA+ and LTE evolution, market awareness of multiple device usage is lagging. Most consumers think of wireless in terms of one device per user., but this will start to change in 2011 as the focus shifts from the dominance of WebPhones to the multiple device market environment.

Trend #3 The friction between LTE/HSPA and WiMAX will fade.

Due to convergence of devices and networks and operators’ focus on delivering competitive services, media and industry focus will be less on the debate between the two technology camps and more on the delivery of profitable common attributes of broadband and multi-service IP environments.

Trend #4 Android will continue to gain ground on Apple.

Google-led Android and sister effort Chrome OS and app stores will gain market share and recognition to end the year more as equals. Android/Chrome will largely overcome an image problem: while Android devices now outnumber the iPhone and applications have swelled, Apple starts the year with the impression it remains the clear market innovator – this will have changed by year’s end.

Trend #5 Growth outside of North America and Europe will become more profound.

While the focus on LTE developments in the US and Japan will capture many headlines, the influence of populous regions outside of developed markets will shift the balance of industry influence. Indian operators’ decisions will come down on the side of LTE rather than WiMAX, and further defections are likely. China and India will shape up as innovators in low cost WebPhones and tablets and the applications that help drive them.

Below we provide some more specific 4G predictions and forecasts by category:

LTE

The worldwide LTE subscriber base will reach 6.52 million in 2011. Leading LTE operators will be Verizon Wireless (USA) and NTT DoCoMo (Japan), with 2.66 million and 2 million subscribers respectively.

There will be a cumulative number of 219 LTE commitments, 71 trials and 57 commercial deployments for the FDD-LTE standard; and 26 commitments, 12 trials and 4 deployments for TDD-LTE.

TDD-LTE will be used as an extender of network capacity in 2011 (TDD femto/picocells will be implemented). Telefonica O2 (Germany) could become the first commercial adopter of this approach, using FDD for outdoor coverage and LTE TDD for urban capacity.

Europe and North America will be the leading regions in terms of commercial LTE deployments, accounting for 22 and 15 respectively.

WiMAX

The Global WiMAX subscriber base will reach 18.87 million in 2011. The regions with the greatest contribution of WiMAX subscribers will be North America and Asia-Pacific, with 8.5 million and 4.74 million subscribers respectively.

The number of WiMAX deployments will slightly decrease for the first time ever in Europe. The failure of several greenfield operators to run profitable WiMAX services, and the momentum of LTE gaining commitments from all mobile carriers, are the reasons for this decrease from the current 164 to 159. However, the number of subscribers will increase considerably, from 1.38 million to 2 million, because of Yota’s delayed switch to FDD-LTE.

Backhaul

Wireless backhaul will recover from the market size reduction it has suffered in 2010. Innovative wireless backhaul technologies such as e-band, free space optics and NLOS backhaul (point-to-multipoint) will help to increase market size to close to US$ 5 billion.

TD-LTE (2.3 and 2.6 GHz) and NLOS backhaul (also in 3.5 GHz) systems will make use of the spectrum left vacant by former WiMAX deployments. NLOS backhaul will focus on 3.5 GHz (available worldwide except in the US), since it is the only band among those covered by WiMAX that is not being addressed by TD-LTE. However, the deployment of TD-LTE by most of 2.6 GHz spectrum licensees is not certain, so there are also chances for NLOS backhaul deployments in that band. The 2.3 GHz band, under-utilized in the US, poses another good opportunity for both technologies.

Femtocells

There are many indications from major mobile operators such as China Mobile, NTT DoCoMo in Japan, and Taiwan’s Chunghwa Telecom that femtocells will play a big part in their network rollout strategy starting next year. Maravedis predicts that this larger group of operators will boost the adoption of femtocells across the world more quickly than originally anticipated. Femtocell pricing will continue to be a barrier for widespread adoption. However, we expect the price to fall to as low as US$70-80 in 2011 from its current US$100 price. We further expect the demand for femtocells will be highest in 2012, when upfront payment is expected to be below US$50.

Devices

We expect smartphones to come to dominate the device market over the next five years. Market share leadership will, in turn, be driven by the success of the individual ecosystems. We believe that market support exists only for a limited number of ecosystems. Consumers will not adopt new closed ecosystems when compared with the choice of the leading ecosystem, Apple (which happens to be closed) or an open ecosystem. We expect RIM and HP Palm to fail to bring new customers to their solutions, or even to maintain their current market share. With regard to new open ecosystem entrants such as MeeGo and Windows Phone 7, we believe that the key to their success will be the creation of holistic ecosystems involving deep media and application libraries, consumer and enterprise product tie-ins, and integrated cloud services. Although this is a difficult challenge for both companies, Microsoft appears to be much better equipped for this task than Nokia.

Tablets are another new element of the smartphone revolution, and it is still unclear whether this is a completely new product segment or rather a replacement of some of the laptop market. Regardless, Apple has again shown with its iPad that there is a tremendous opportunity for vendors who are able to create innovative and compelling products. Tablets also help to bolster the ecosystems for which they are designed by providing another channel for application sales – one that commands higher prices than the handheld channel.

The changes in the device industry since the introduction of the iPhone have been striking and it is difficult in the midst of such disruption to predict an outcome. 2010 has been a year during which the players have appeared to solidify and publicize their strategic plans. However, we expect many aspects of the industry to be in flux throughout 2011, setting the stage for dramatic changes.

Verizon vs. Clearwire: A 4G Comparison

After much industry speculation Verizon Wireless finally commercially launched its LTE network on December 5th, 2010. The network has been launched in 38 cities covering approximately 110 million people. Major cities include San Francisco, Boston, Chicago, Miami, and Silicon Valley, among others, with nationwide coverage planned by 2011, and a full 3G to 4G upgrade by the end of 2013. The largest market in terms of both coverage and POPs covered is southern California, with 20 millions POPs covered.

Competition between Clearwire and Verizon, which are today the two largest 4G operators in United States, is now intensifying. Verizon will be offering very similar speeds as Clearwire and, starting 2011, more attractive devices including LTE smartphones and tablets.

However, in the short term I don’t believe Clearwire has much to worry about regarding Verizon’s recent announcement. Verizon Wireless’ LTE offering is disruptive compared to Clearwire's WiMAX offering. The former has introduced one LTE plan of 5 GB at US$50/month and another of 10 GB at US$80/month (both plans charge US$10.00 per 1 GB overage fee), compared to Clearwire’s WiMAX plans providing unlimited data for only US$45/month (users consume in average 7GB per month). 5 G might not be enough for most of Verizon’s customers, who are likely to turn to the 10 GB plan to satisfy their data needs. Consumers will know how much data they are using via Verizon text alerts when they reach the 50%, 75%, 90% and 100% usage marks.

Speeds for the two carriers’ offerings are about the same – 5-12 Mbps downlink for Verizon and 3-6 Mbps for Clearwire (with burst over 10 Mbps). It is doubtful from a customer point of view whether 6Mbps or 12Mbps downlink makes much difference. What Verizon’s customers will notice right away and will be happy about is the 10x increased speed of the 4G network as compared to 3G. Speed is important but so is latency. Verizon’s spokesman explained that the latency on its 4G network is half the latency on the 3G network, and almost near the latency a user can experience on a wired network.

Not only has Verizon priced its capped LTE data plans higher than Clearwire's unlimited 4G data plan, but its available LTE USB dongles (one from LG and another one from Pantech), will not compete against Clearwire's 4G smartphones (HTC and Samsung). There is a clear time-to-market advantage for Clearwire in terms of devices and cities covered. It has today more than 45 4G embedded laptops and netbooks, 2 smartphones and 4 USB dongles, while Verizon has only introduced 2 USB dongles. Although Verizon has said that more LTE device models will be available within weeks and will be 3G compatible, we believe that the real momentum for Verizon's LTE network will be by mid-2011, when the first LTE capable smartphones hit the market. Verizon has announced Ericsson and Alcatel-Lucent as key partners for its LTE network rollout to RAN infrastructure, Nokia Siemens and Cisco as suppliers of core IMS infrastructure, and LG and Pantech as initial device suppliers.

The greatest disadvantage for Verizon is that its LTE network capacity will be limited by its spectrum resources of 34 MHz in the 700 MHz band, as compared to +150 MHz in Clearwire’s 2.5 GHz band. Clearwire will leverage its superior spectrum assets to continue offering unlimited data plans, which Verizon will not be able to support.

All this sounds good for Clearwire: with approximately 4 million WiMAX subscribers, a wide array of devices, and a superior spectrum position than any other carrier in the United States, the operator has gained momentum in the last 2 years since its WiMAX/4G network was first launched. But one aspect that we cannot omit is the difficult situation that Clearwire is going through to gain additional funding to continue network development. Lack of funding in the coming six months will inevitably hurt Clearwire’s 4G position.

3G and 4G will be equally important for Verizon, at least in the short term. Verizon will leverage its 3G network to support voice and 4G network to support data applications, the two networks will work simultaneously. At some point in the future when its 4G footprint is larger, Verizon will put voice and data together on the 4G network, however VoIP over LTE will not be available but until late 2012 or early 2013.

The nature of the Verizon Wireless’ 700 MHz spectrum will allow lower initial deployment costs to achieve similar coverage as Clearwire, which is deploying in the 2.5 GHz band. This is offset by the differences between deployments: Verizon will blanket much more suburban, traffic corridor and marginal suburban areas than Clearwire. Therefore, its coverage will be about twice of Clearwire’s down the road.

Verizon’s LTE growth is dependent upon achieving nationwide coverage, which will not take place until 2011. Next year will witness a rapid pace of deployments and the introduction of a growing list of LTE devices. However, before rapid growth can take place, deployment first must mature, devices and services must be rolled out, and advertising campaigns must be mounted.
