NTT DoCoMo plans LTE launch in late 2010
Source: Network World
The high-speed mobile broadband service will be available in half of Japan by 2014.
NTT DoCoMo plans to launch high-speed cellular data services based on LTE (Long Term Evolution) technology in December 2010, it said Thursday.
LTE is an IP-based system seen as a replacement for 3G-based HSPA (High Speed Packet Access) and its introduction is expected to reduce the per-byte cost of data communications.
The Japanese service will initially be aimed at PC users, with DoCoMo offering card-type terminals for laptops, said Ryuji Yamada, president and CEO of NTT DoCoMo at a Tokyo news conference. It will be expanded to include handset terminals from 2011, he said. Those terminals will be dual-mode devices that use LTE networks where available and fall back to 3G networks to provide nationwide coverage.
By 2014 the carrier plans to provide LTE service to 50 percent of Japan from around 20,000 base stations.
The following is the slide summarizing their LTE status/view from their earnings presentation. The entire presentation can be downloaded from http://www.nttdocomo.co.jp/english/corporate/ir/binary/pdf/library/presentation/090730/all_e.pdf. - Hyung

LTE the Only Road to Wireless 4G in China
Source: In-Stat press release
Although competing 4G technologies will come to the fore in other countries, LTE will be the only route to 4G wireless service in China, reports In-Stat http://www.in-stat.com. TD-LTE, one of the two flavors of LTE, will receive much more support than LTE-FDD in China. In 2010, China Mobile will use TD-LTE to construct a pre-commercial LTE network.
“China Mobile will be the first operator to launch commercial LTE operation,” says Anty Zheng, In-Stat analyst. “This will happen in limited areas in 2011. China Telecom and China Unicom will, we believe, follow China Mobile’s lead.”

Source: Linear Technology press release
A new wide bandwidth active upconverting mixer, the LT5578 from Linear Technology, delivers high dynamic range performance from 400MHz to 2.7GHz, supporting all of the allocated LTE (Long-Term Evolution) broadband wireless services. At 900MHz, the mixer offers 27dBm Output IP3 linearity and best-in-class noise floor of -160.5dBm/Hz at an output level of -5dBm, enabling outstanding transmitter dynamic range. In addition, the mixer has 1.4dB conversion gain with integrated RF balun transformers that provide a single-ended RF output and LO (Local Oscillator) input to simplify designs while reducing external component count. Moreover, the device’s LO input is internally buffered, requiring a drive level of only -1dBm. This results in an outstanding LO-to-RF leakage of -43dBm.

3G Americas, a wireless industry trade association representing the GSM family of technologies including HSPA and LTE, today announced that it has published key recommendations for utilizing non-standard spectrum bands in a white paper titled, 3GPP Technology Approaches for Maximizing Fragmented Spectrum Allocations. The paper discusses the emerging challenges for spectrum stakeholders involving how to permit wider spectrum usage by operators using various broadband technologies and current spectrum allocations. These challenges are especially poignant in “fragmented” spectrum bands (which depart from globally or regionally harmonized bands), such as the AWS III band in the U.S., and in the potential for country specific allocations of the 2.6 GHz IMT band and “Digital Dividend” spectrum outside of the U.S.

While major CDMA operators like Verizon Wireless and Sprint are moving directly to 4G, the CDMA Development Group and other CDMA proponents have long stressed there is an alternative, EV-DO Revision B, which would allow operators to boost capacity without building new networks or acquiring new spectrum. ZTE, however, isn’t taking sides in the argument. Instead, it’s splitting difference, announcing today a new base station that will support both the Rev. B upgrade and LTE on the same platform.

NSN Backs Away From WiMax
Source: Unstrung
As Nokia Siemens Networks prepares to revamp its mobile development strategy with the planned $650 million acquisition of Nortel Networks Ltd.'s key CDMA and LTE access wireless assets, the vendor has made another significant wireless strategy move -- it's scaling down its focus on WiMax.
The Finnish-German vendor has decided to divert R&D resources away from WiMax to Evolved High-Speed Packet Access (HSPA+) and Long Term Evolution (LTE), and will no longer make its own standalone WiMax base station, but will rely more on partners instead, Marc Rouanne, head of radio access at NSN, tells Unstrung.

3G Americas Publishes Report on Smart Antennas (MIMO Technologies)
Source: 3G Americas press release
3G Americas, a wireless industry trade association representing the GSM family of technologies including LTE, today announced that it has published an educational report titled, MIMO Transmission Schemes for LTE and HSPA Networks as a tool to increase awareness of smart antenna systems – also known as multiple-input multiple-output (MIMO) technology – and help guide their deployments in HSPA and LTE networks within 3GPP’s specifications and technology standards. The 3GPP evolution continues to be the leader in standardizing the most advanced forms of multiple-input multiple-output (MIMO) antennas.

Recession dividing LTE and WiMax
Source: ZDNet Asia
The global economic situation may widen the rift between LTE (long term evolution) and mobile WiMax adoption between mature and emerging markets, according to Ovum.
The analyst firm said in its latest report, the recession is expected to slow revenue growth for operators in the short term, although the volume of connections will keep rising. This will lead to lower ARPU (average revenue per user), in turn driving the uptake of LTE in mature markets, as telcos look to upgrade to next-generation networks to capture data revenues, said Ovum.

Nokia Siemens Networks has shed light on what it plans to do with the Nortel Networks Ltd. Long Term Evolution (LTE) assets.
NSN's head of radio access, Marc Rouanne, tells Unstrung that the vendor plans to incorporate Nortel's LTE algorithms and software into its own flagship Flexi base station platform. NSN will not maintain or have to integrate two separate LTE base station product platforms.

Nortel 4G patents may not be worth that much

Embattled Canadian vendor Nortel may have held on to some of its key LTE patents when it flogged much of its mobile business to Nokia Siemens Networks last month, but there is some debate as to whether that IPR will be the nice little earner Nortel hopes.

Nortel's LTE Patent Goldmine

There's a good reason why Nortel Networks Ltd. seems keen to hold on to its LTE (Long Term Evolution) access intellectual property and not flog it to Nokia Siemens Networks as part of its wireless asset fire sale: Those patents are worth an absolute fortune!
That, at least, is the view of JP.MorganChase analyst Ehud Gelblum, who issued a research note Monday stating that Nortel's LTE patents could generate royalty revenues of hundreds of millions of dollars, possibly even as much as $2.9 billion.
