A group of leading telecom manufacturers and network operators formed a joint initiative aimed at driving forward the realization of the next-generation of high performance mobile broadband networks based on 3GPP Release 8 "Long Term Evolution/System Architecture Evolution" (LTE/SAE) specifications.

Comprised of Alcatel-Lucent, Ericsson, France Telecom/Orange, Nokia, Nokia Siemens Networks, Nortel, T-Mobile and Vodafone, the LTE/SAE Trial Initiative heralds a new chapter for the mobile industry with network systems targeted to support mobile broadband peak data rates exceeding 100Mbps. In line with 3GPP requirements, the technology aims to provide a mobile broadband service that outperforms both 3GPP Release 6 HSPA, as well as current fixed line DSL data rates while maintaining and extending the mobility and coverage benefits of 3GPP networks such as GSM. In addition, 3GPP LTE/SAE networks are expected to enable lower operating costs for operators as well as higher data-rate, lower latency end-user services, and an improved end-user wireless mobility experience.

To meet these objectives, LTE radio systems are designed to provide both greater levels of radio spectrum efficiency through use of new radio transmission schemes and advanced multi-antenna technologies, and a more flexible utilization of radio spectrum through support of carrier bandwidths ranging from 1.25MHz to 20MHz.

The companies involved in the initiative will collaborate on demonstrating the potential of 3GPP LTE/SAE mobile broadband technologies through a series of joint tests including radio transmission performance tests, early interoperability tests, field tests and full customer trials. Joint activities will commence this month and are expected to run for a period of 18-24 months.

The joint test results will be used by the participating members in ongoing technology developments and 3GPP LTE standardization work, and will also help define and validate operator network launch plans. In addition, the initiative will help validate the emerging LTE ecosystem including devices and applications, with a view to enabling commercial deployments in the 2009-2010 timeframe. The LTE initiative will also work closely with NGMN Ltd to take into account the NGMN performance requirements.
