MWC08: Everyone talked about their LTE offering

In the recently concluded Mobile World Congress, everyone made sure that they talk about their LTE offering. This included the Handset manufacturers, Mobile operators, chipset people and even the Applications developer who were telling that their applications would work better than others, etc.

Here is a roundup of some stories (a bit old though):

At the Mobile World Congress, Samsung and LG express their yearning for 4G in Mobile WiMAX and LTE (Long Term Evolution), respectively.

Samsung demonstrates the interworking between Mobile WiMAX and GSM in cooperation with Alcatel-Lucent. The company’s dual-mode phone supporting both Mobile WiMAX and GSM realizes seamless video streaming, moving from Mobile WiMAX to GSM.


Besides various Mobile WiMAX solutions, Samsung unveil Access Service Network (ASN) systems such as U-RAS Flexible and U-RAS Light Series 3 working as a base-station for expanding coverage of hot zones, inside a building or at home. Using ASN, service providers will be able to facilitate integrated services such as quadruple play service and thereby improve Mobile WiMAX network as well as enlarge service coverage, the company explains. Samsung also demonstrates OFDMA, the next generation Mobile WiMAX, in high-resolution video streaming at 1Gbps download, and unveils a wide range of Mobile WiMAX devices such as USB Dongle, PC cards, PDA, UMPC, PMP and notebook computers.

LG joins forces with Nortel, its strategic partner in telecommunications equipment, to demonstrate wireless multimedia transmission using LTE, a strong candidate for 4G mobile standard. The LTE platform introduced by LG supports 60Mbps download and 40Mbps upload, up from 20Mbps for both upload and download realized in the last year’s demonstration.

China Mobile has joined Vodafone and Verizon Wireless in trialling the LTE technology that will take 3G through to 3.5G before the world finally looks at 4G - and in doing so, has shaken the established standards by adding its own Chinese-oriented technology to the LTE mix.

It announced that the three-way operator trials "will focus on the testing of LTE in the Frequency Division Duplex (FDD) paired spectrum, and the Time Division Duplex (TDD) unpaired spectrum - both technologies which are seen by some as an attempt to avoid payments of royalties to Western IP holders.

If there was any question that LTE is dominating the charge toward 4G, Qualcomm, the primary supporter of competing UWB technology, is now deploying a number of chipsets with LTE support. Verizon is one of Qualcomm's largest customers, and their decision to go LTE has apparently broadened Qualcomm's horizons. The company also says they'll be conducting HSPA+ tests throughout 2008.

"Motorola's vision for next-generation networks is one of a 4G radio access technology with huge bandwidth like LTE, combined with a flat IP architecture tied to IMS, enabling an unlimited variety of media mobility experiences. Our carrier customers want technology solutions that fit with their business plans - regardless of whether their 4G choice is LTE or WiMAX that will deliver the user experience and capacity necessary to support the growing demand for bandwidth intensive mobile, multimedia applications," said Fred Wright, senior vice president, Cellular Networks and WiMAX, Motorola.

LTE will provide users with a personal media experience similar to that of fixed line broadband both in terms of bandwidth and latency, meaning applications that can be delivered today on fixed line will soon be available over the air and fully mobility with LTE. By combining expertise from across Motorola including, chipsets, network and video head-end solutions, and professional services, the Motorola LTE ecosystem will enable true media mobility, delivering innovative applications that can help operators to increase revenues and gain a competitive advantage.

Motorola is pioneering mobile broadband innovation and leveraging its experience, research and expertise in OFDM, as well as developments in chipsets, devices, high-speed backhaul solutions, collapsed IP architecture and video head end solutions, to deliver its end-to-end LTE solution.

Nortel, LG and LG-Nortel demonstarted at mobile event that how LTE enables the user to watch videos streamed from YouTube or monitor his home security through online video surveillance system access while traveling.

“Nortel is moving forward aggressively on LTE in order to bring to market a solution capable of supporting high demand applications like video and interactive services that will have an impact on operators''' bottom lines and revolutionize the user experience," said Doug Wolff, general manager of LTE, Nortel.


With the LTE market just starting to develop, Alcatel-Lucent and NEC Corp. believe combining their resources early on will help them develop a market advantage. Alcatel-Lucent CEO Patricia Russo said the move is an offensive play, rather than a defensive one.

Japan’s NTT DoCoMo Inc. already has selected NEC to help deploy its LTE solution, while Verizon Wireless and AT&T Mobility have selected Alcatel-Lucent as trial partners for planned LTE deployments.The two network vendors said they plan to participate in trials in 2008 and launch a commercial network solution in 2009. The companies will use a common LTE platform and then customize the configuration depending on the needs of the carrier. Alcatel-Lucent and NEC have been working toward the joint venture for about six months.

I am interested in making a comparative study of the various features in the LTE system by different vendors like Samsung, Ericcson,Motorola,Nortel,Alcatel-Lucent..
Can anyone help by sending the weblink for reference..
