1. National digital terrestrial television in standard or high definition. Ofcom has already demonstrated that new High Definition and Standard Definition channels can be delivered on Freeview without the need for any digital dividend spectrum. This was the subject of proposals published by Ofcom on 21 November 2007. In addition, Ofcom will package the cleared spectrum in a way that makes it suitable for more digital terrestrial television, but it will not be reserved for this use.
2. Cognitive radio. This is a new wireless technology that shares with other services by detecting when spectrum is not being used. It is hoped that cognitive radio devices will be able to work together to create so-called ‘mesh networks’ that can support a range of wireless applications such as high-speed broadband access across urban and rural locations. Ofcom is proposing to allow cognitive radio to use the interleaved spectrum provided it can be shown this does not cause interference to other spectrum users.
3. High speed mobile broadband and mobile television. Our market research has found keen interest in high speed mobile broadband. We will package the cleared spectrum in a way that makes it suitable but not reserved for these uses.
4. Local television. Ofcom will auction packages of interleaved spectrum suitable but not reserved for local television in some 25 locations across the UK where there is evidence of demand to provide this type of service.
5. PMSE spectrum users. Ofcom will award most of the available interleaved spectrum by ‘beauty contest’ to a band manager who will be required to manage spectrum for PMSE users. This process will be designed to ensure that the licensee’s interests are aligned with those of PMSE users. The licensee will earn revenue by charging for access to the spectrum but will be required to meet reasonable demand from PMSE users on fair, reasonable and non-discriminatory terms. These measures will ensure that PMSE users can continue to access spectrum while moving towards a more market-based approach over time.

Telecom Italia Dumps UMA for FMC
December 6, 2007
Telecom Italia SpA has decided not to use unlicensed mobile access (UMA) for its fixed-mobile convergence (FMC) service Unica, and has relaunched the service with a homegrown SIP-based solution.
The operator made the technology change because of Italy's regulatory regime and the limited availability of UMA-enabled handsets.
Telecom Italia launched a limited commercial FMC service earlier this year with UMA network controllers from Motorola Inc.. But the service got tangled up in a regulatory tussle -- along with Vodafone Italy 's home zone service -- at national regulator Agcom .

Now with Sprint declaring it is interested in spinning off its WiMAX assets, one can only speculate what is the future for a technology that is rapidly being marginalized? Continuing delays in Certification (now looking like 3Q 2008), means that mobile WiMAX is losing its lead over LTE, which will start trials next year. (See NSN Touts 4G post).
Ericsson and QUALCOMM, both of which have declared their support of 3GPP standards and not IEEE standards, must be feeling quietly confident and looking forward to a prosperous New Year!
Sprint and Clearwire recently put the kibosh on plans the two companies had drawn up to cover more than 100 million people with WiMax. The companies had never signed a definitive agreement, and mounting pressure from Sprint's investors was just one reason that led to the annulment of the agreement.
Saleh reiterated to the investors that Sprint is mulling its options, but has a team studying the idea of a sale. What company or entity Sprint would sell its WiMax network to is unknown. Such a move would have several large consequences.

Arun Sarin, CEO of Vodafone, and Verizon Communications Inc. chairman and CEO Ivan Seidenberg, spoke about the technology choice at the Goldman Sachs Communacopia conference yesterday. Vodafone and Verizon control Verizon Wireless through a joint venture.
Sarin laid out a path toward LTE evolution within the next three to four years. Vodafone relies on GSM- and HSPA-based technology for wireless high-speed data access in its properties abroad, while Verizon Wireless—45% owned by Vodafone—is a CDMA operator whose most recent network upgrade has been to EV-DO Revision A.
The news marks a serious setback for CDMA backers, as Verizon Wireless is one of the world’s largest supporters of the technology. Indeed, the news puts Ultra Mobile Broadband—which is Rev. C on the CDMA network-upgrade path—into question, as no operator has yet publicly voiced intentions to move toward the technology.

Owners of the right to use these parts of the spectrum would also be able to trade these rights to other companies.
By lifting restrictions, Ofcom said that operators would be able to boost the data carrying capacities of their 3G networks for relatively little cash.
The emerging Femtocell industry may find these proposals somewhat disconcerting as the key application is to improve indoor coverage of 3G services. (The other benefit is to allow fixed-mobile substitution and carry data traffic over the fixed broadband network).

The Ericsson F3507 module delivers High Speed Packet Access (HSPA) at rates of 7.2 Mbits/second for a downlink and 2 Mbits/s for an uplink. The mini PCI device includes a third-party global positioning system chip and consumes a total 2W peak.
Ericsson aims to compete on price with Qualcomm when the modules ship in January. The company would not disclose its target price yet, but said its strong patent position and use of mainly in-house chips would make its costs significantly lower than competitors such as Novatel and Sierra Wireless who buy chips and pay significant royalties to Qualcomm.

Telsima Announces Shipment of 10,000 Base Station Sectors; Details Innovative Mobile WiMAX Strategy and Product Portfolio
Telsima has also developed a new architecture called TRUFLE™ ASN for migration to Mobile WiMAX networks for those operators who have a need to serve fixed and mobile users with the same WiMAX network. TRUFLE ASN allows for operators to profitably operate 802.16e network with fixed and mobile users and to migrate to a fully Mobile WiMAX network based on their business needs. This new architecture, which is currently being field-tested by Tier-1 operators, is NWG compatible – allowing operators to upgrade the network to Profile A or C compliant Mobile WiMAX while leveraging their initial infrastructure investment.

* Two widely expected requirements for beyond 3G technologies are that they be OFDMA-based, and that they support 100 Mbps for wide area mobile applications.
* With the dominant worldwide technology currently being GSM/EDGE, and HSPA and EV-DO handsets not expected to be important until 2012, beyond 3G technology roll-outs will most likely start in the 2010-2012 timeframe.
* It is widely believed that mobile operators will initially deploy beyond 3G cautiously, relying on their EV-DO or HSPA networks to provide ubiquitous coverage.
* Drivers of LTE, UMB and 802.16m WiMAX adoption will include the following: the re-allocation of older spectrum for IMT Advanced technologies; the resolution of any WiMAX IPR issues; the creation of FDD profiles for 802.16e WiMAX; the uptake rate of 802.16e in Mobile PCs; the uptake rate of 3G cellular in Mobile PCs; the continued evolution of the mobile handset; and an increase in the uptake rate of wireless broadband technologies into portable CE devices.

EU seeks more radio frequencies for wireless services — EUbusiness - EU business, legal and financial news and information - EUbusiness.com
By bringing down the cost of offering third-generation mobile services, the Commission hopes that companies would be encouraged to develop such technologies, which have found little popularity so far.
The use of lower frequencies would also give third-generation services broader geographical coverage, which would likely boost their popularity as well.
"Radio spectrum is a crucial economic resource which must be properly managed across Europe to unlock the potential of our telecoms sector," said EU Telecoms Commissioner Viviane Reding.

According to ABI Research principal analyst Philip Solis, "Today, consumer FMC services that are based on Wi-Fi use UMA to manage the connection choice and handover between Wi-Fi and cellular networks. These services are ramping up quickly in Europe, due to intense competition between Orange, BT, and other mobile operators. In North America, T-Mobile USA is about to go nationwide with its UMA-based FMC service as well."
"However," adds research director Stuart Carlaw, "mobile operators such as Vodafone, SFR, Softbank, and Sprint are at the leading edge among carriers exploring femtocell technologies. With their ability to work with any handset, and their potential for encouraging high data use, femtocells are very attractive when compared to VCC and UMA-based Wi-Fi services."

1.1 The following points highlight Ofcom's main conclusions on candidate bands following a review of the responses to the consultation it published on WRC 07 agenda item 1.4 on 27 February 2007:
* Ofcom’s preference for the band 470 to 862 MHz is a co-primary mobile allocation in Region 1 in the table of allocations in Article 5 of the Radio Regulations;
* Ofcom supports a co-primary mobile allocation for the sub-band 3400 to 3800 MHz and an identification for IMT coupled with a requirement for an associated Resolution to reflect the need to provide appropriate protection for existing satellite use whilst facilitating access to the band for new use;
* In view of the emerging opposition from various European administrations to the sub-band 3800 to 4200 MHz Ofcom supports a position of no change to the table of allocations;
* For the other candidate bands, we have concluded that there is no need to change the position proposed in the consultation however the UK may wish to consider the merit in signing up to any "no change" proposals developed within Europe.

WP 8F has delivered a number of key Recommendations and Reports that update and expand the family of IMT-2000 radio interfaces, establish the foundation for IMT-Advanced, and call for additional spectrum for IMT. It has woven together a definition, a recipe, and a roadmap foreseeing the future beyond 3G that is comprised of a balance between a market and services view, a technology view, and a spectrum view. Along with regulatory aspects, these are the key elements for business success in the wireless industry, and ITU-R continues to deliver value to industry and government.
Working under a mandate to address "systems beyond 3G", WP 8F progressed from delivering an initial vision to establishing a name for the future (IMT-Advanced) and set out principles for the process of development of IMT-Advanced. These deliverables stimulated research and development activities worldwide, spawned ideas on potential technologies, and promoted views on spectrum required to address a rapidly growing wireless world.
With this acquisition and assuming closing of other pending spectrum purchases, Clearwire's U.S. spectrum holdings increased to approximately 14.0 billion MHz-POPs, covering an estimated 223 million people with varying depths of spectrum. In addition, Clearwire holds approximately 8.7 billion MHz-POPs of spectrum in Europe, covering approximately 199 million people. Clearwire holds one of the world's largest portfolios of next-generation wireless broadband spectrum in the frequency bands identified by the mobile WiMAX standard.

Operators have trouble finding customers for combined deals offering fixed and mobile services, which are complicated to set up and lack choice in handsets, industry executives said at a convergence conference in Amsterdam that runs until Thursday.
LTE brings to the market 25 years of operating experience using TDM and CDMA technology. It aims to use that, combined with OFDM, and other techniques, to provide the best of both worlds, perhaps stealing WiMAX's thunder. This also takes the industry from the current two-network approach of circuit switching for voice, and packet switching for data to a single IP network for both services.
"LTE faces competition from other broadband wireless technologies and it will need to demonstrate clear technical and economic advantages to convince network operators," says ABI Research analyst Ian Cox. "The mobile variant of WiMAX will start to appear in 2007 as the WiMAX Forum Certification program ramps up. The industry is also working on HSPA+, which could offer the same performance in a 5 MHz bandwidth. Without additional spectrum, operators could face a difficult choice."
Cox further comments that, "LTE is the NGN for the mobile industry and is being standardized by 3GPP with the full support of operators via the NGMN Group."
Long Term Evolution (LTE) of 3G technologies is about to benefit from Release-8 of the 3GPP standard, planned for the third quarter of 2007. The potential rewards of LTE are simplicity of operation, a "flat" architecture offering low latency, and spectrum flexibility. Backwards compatibility and roaming with 2G and 3G networks are added bonuses, along with lower power consumption and improved performance, . LTE could also unite the W-CDMA and CDMA communities because of its spectral flexibility.
For vendors, LTE will allow development of a new market to replace declining 3G revenues.
For users, says Cox, LTE will enable broadband services, including VoIP, to be offered over SIP-enabled networks. Each service will be IP-based, offering high data rates and low latency, with on-line gaming becoming a reality along with mobile network data speeds comparable to those of fixed networks.

DBD, Germany's first and largest WiMAX operator, provides broadband access services in the 3.5GHz band for both residential and enterprise customers. DBD has now rolled out services in more than forty networks, the largest deployment being in Berlin.
In addition, DBD is one of the first operators to deploy Airspan's VoiceMAX technology on a WiMAX network. VoiceMAX gives operators the ability to deliver carrier-grade VoIP services through a software suite that provides VoIP admission control, which monitors the user experience of voice calls over WiMAX networks. VoiceMAX enables wireless operators to prevent network congestion and prevents data traffic from degrading voice quality as the network is loaded with IP traffic.
"Airspan's WiMAX products have allowed DBD to strengthen its leadership in rolling out WiMAX broadband infrastructure in Germany," said Eric Stonestrom, Airspan's president and chief executive officer.

The newest Motorola WiMAX trial agreement is with TVA, a multi-services operator in Brazil, which will conduct a trial for the use of mobile WiMAX technology (802.16e) in Rio de Janeiro. The solution will cover central Rio and part of the south of the city, providing wireless broadband services with voice, data and multimedia capacity for a select group of users.
The WiMAX platform, including use of the 2.5 GHz spectrum in line with Anatel regulations, enables rapid digital inclusion, as well as an opportunity to provide multimedia (voice, data and image) services. By digitalizing its MMDS (Multipoint Multichannel Distribution System) network, TVA is able to expand its service offering, creating a new model for competition.
In the agreement, Motorola will supply its wi4 WiMAX access points and end user equipment. WiMAX 802.16e permits indoor installation of customer premises equipment without line of sight to the radio base stations, ensuring high user service capacity. The technology also permits high data rates and a wider range of coverage than other currently available technologies.
The trial period will enable TVA to assess the performance of the technology in the differentiated demographic topology of the city of Rio de Janeiro, as well as the mobile TV, video, VoIP, and media streaming services and data applications.

1GHz new spectrum will be needed to meet growth in demand for very high-speed mobile services by 2020
WRC-07 is the right time to identify new spectrum: our industry cannot afford to wait until the next conference in 2011 to identify this additional spectrum
The UMTS Forum considers that at least 2 x 30 MHz of globally harmonised paired spectrum in the band 470-862MHz would provide a viable minimum coverage extension band for IMT-2000/UMTS
Current regulatory provisions should be reviewed in order to protect the 2500-2690MHz band from satellite interference that could significantly reduce the coverage and capacity of UMTS networks.
This year's World Radiocommunication Conference (WRC-07) is a landmark event for our industry. Preparations for WRC-07 have been ongoing for several years and CPM, the Conference Preparatory Meeting, is an important milestone in the preparations.
In the UMTS Forum we represent a significant group of stakeholders who are directly interested in spectrum topics in the context of the development of public mobile communication networks including UMTS/IMT-2000. Consequentially the UMTS Forum is actively contributing to the ITU preparatory process for WRC-07 including this month's CPM meeting in Geneva.
Harmonised spectrum to meet future global market demand
The UMTS Forum has a close interest in assessing the amount of spectrum will be needed for the future development of IMT-2000 and systems beyond IMT-2000 ('IMT-Advanced'). Here we have already estimated in the UMTS Forum that as much as 1GHz of new spectrum will be needed to meet growth in demand for very high-speed mobile services by 2020. These frequencies are needed in addition to spectrum that is already identified for UMTS/IMT-2000 at the earlier WARC-92 and WRC-2000 meetings, namely 585MHz in Europe. We also believe that these bands for advanced services should be globally common and located below 5 GHz in order to support full mobility with an acceptable trade-off between affordable cost and full area coverage.
Existing bands are without doubt insufficient to satisfy the spectrum demand for IMT-Advanced. Tomorrow's mobile applications and services demanding our predicted traffic volumes with 100 Mbps/1Gbps peak data rates cannot perform satisfactorily within today's IMT-2000 spectrum bands. WRC‑07 is without doubt the right time to identify new spectrum for IMT-Advanced After all, it has typically taken around a decade between the time when the spectrum is identified and when it is actually used by the market. Our industry cannot afford to wait until the next conference in 2011 to identify this additional spectrum that is going to have a massive socio-economic effect on our society over the next two decades.
Serving growth markets
Another key topic at WRC this year is the cost-effective extension of mobile coverage using affordable UMTS/IMT-2000 systems and terminals to serve growth markets like China, India, Eastern Europe, Latin America and Africa where there are large numbers of people in geographically scattered areas of low population density. The switchover from analogue to digital broadcasting is expected to free some spectrum in the band 470-862 MHz, and these 'digital dividend' frequencies are of particular interest to provide extended coverage. In the UMTS Forum we have shown that significantly fewer base station sites are needed to provide UMTS/IMT-2000 coverage at these lower frequencies compared to today's 2 GHz core bands. In Region 1, the ITU Regional Radiocommunication Conference 2006 (RRC-06) established a frequency plan for terrestrial digital TV broadcasting. The results of RRC-06 allow greater flexibility in the use of broadcasting bands: discussion continues on how to introduce mobile use into the band.
The UMTS Forum is therefore urging that WRC-07 identifies a new Coverage Extension Band in the lower frequency bands for IMT-2000 to address part of WRC-07 Agenda Item 1.4 and its related Resolution 228. This new Coverage Extension Band, we believe, should be allocated on a primary basis for mobile services in all three ITU Regions and identified for terrestrial IMT-2000. The UMTS Forum considers that at least 2 x 30 MHz of paired spectrum from the band 470-862 MHz would provide a viable minimum Coverage Extension Band for IMT-2000/UMTS.
Safeguarding UMTS/IMT-2000 systems against interference
One further topic of great importance at WRC-07 is the protection of the 2.5GHz band from satellite interference. The 2500-2690 MHz band was previously identified for IMT-2000 on a worldwide basis by WRC-2000. Moreover, this band is allocated to various satellite services, in particular Broadcasting Satellite Service (BSS), Fixed Satellite Service and BSS (sound) service. As a UMTS extension band, the 2.5 GHz band requires protection from interference from those satellite services. Current regulatory provisions, including satellite radiation powers, have to be reviewed to ensure this protection on a long-term basis. Satellite interference could have a very detrimental effect by significantly reducing the coverage and capacity of UMTS networks. It should be noted that WRC-03 adopted appropriate new regulations that ensure the protection of UMTS networks from BSS (sound) interference. Respective regulations will have to be adopted at WRC-07 for other space services

Mobile phones were the next worst invention, according to 17 per cent of those questioned. Nuclear power, television and the Sinclair C5 came joint third with nine per cent.
(Nothing against West or Sprint Nextel, but the only wireless technology the carrier is not currently using or planning to use is GSM, the technology that gives the 3GSM World Congress its name.)
Described by some at the conference as the elephant in the room, WiMAX made a small but entertaining presence at the show, with several sessions having at least one question about the technology. WiMAX has made headway outside of Europe but appears to be having a more difficult time in the heavily regulated EU environment.
The 3GSM WiMAX session included brief presentations by Jake McLeod, principal vice president and CTO of Bechtel Communications, who brought a down-home feel to his time on stage, and Hwan Chung, vice president at Samsung Electronics Co. Ltd., who provided attendees with the Korean experience with mobile WiMAX. Chung, as is proper for such a high-tech event, also showed off a pocketful of WiMAX devices.

Microsoft preps cognitive radio prototype for use with TV spectrum - Convergence - www.itnews.com.au
An informal coalition of technology companies, including Dell, Google, Hewlett-Packard, Intel, Microsoft, and Philips Electronics, has asked the FCC to make unused portions of the TV broadcast spectrum available for unlicensed use by wireless devices.
Though the specific devices that might work with this "super Wi-Fi" network have yet to designed, Microsoft is preparing to submit its prototype "cognitive radio" soon. A company spokesman said Microsoft and its partners aim to demonstrate to the FCC that consumer devices can utilize the spectrum "white space" without causing interference with TV or other signals.
"This is all related to the FCC-proposed rulemaking to open up white spaces for additional uses," says a spokesman for Microsoft. "We think there's an opportunity for innovation in using those spaces."

Fellah thinks WiMAX will represent 90% of subscribers who are added in 2012, of whom 75% will be using 802.16-2005 technology.
Some other predictions: "WiMAX chipsets will start to be embedded into laptops in the beginning of 2008, into handheld devices in the beginning of 2009, and into consumer electronics in the beginning of 2010. In this context, Wavesat who has been a pioneer in the development of WIMAX SOCs is well positioned to tap into this future competitive WIMAX mobile market."

On Thursday, Verizon Wireless announced it is upgrading its third-generation wireless network using a CDMA-based technology called Evolution Data Optimized (EV-DO) Revision A (Rev. A) in six markets: Boston; Richmond, Virginia.; Chicago; Gary, Indiana; Salt Lake City; and parts of Florida.
Sprint Nextel has also been upgrading its 3G network with EV-DO Rev. A since October 2006. And last week the company said it offers the service in 24 markets, including some in which Verizon says it will operate, such as Boston, Salt Lake City and southeastern Florida.
The main benefit of upgrading to EV-DO Rev. A is an increase in upload speeds. EV-DO Revision Zero, the first version deployed, offers downloads between 400 kilobits per second and 700kbps with upload speeds of about 50kbps to 70kbps.

While most vendors are working towards delivering their first mobile WiMAX products based on what is known as "Wave 1" mobile WiMAX technology, Navini Networks is already showing the critical "Wave 2" functionality of beamforming on its Ripwave(R) MX platform.
"Smart beamforming is the key technology in the WiMAX standard that changes the RF game, enabling performance superior to other wireless technologies (3G et al) and Navini has been a leader in beamforming for several years," explains Sai Subramanian, VP, Strategic Marketing and Product Management for Navini Networks. "Many of the largest 'personal broadband' networks in Asia, Europe, Africa and the Americas already use Navini's beamforming, which is enhancing commercial service delivery inside homes and offices."
