Nokia announced earlier this week that the LSTI (LTE/SAE Trial Initiative) had achieved a 100 megabits-per-second data transfer speed in recent tests. LTE/SAE is an evolved version of today's mobile phone radio access technology designed for faster data transfer with a simplified architecture, using new transmission schemes and advanced antenna technology. Initial deployment configurations are specified to have downlink rates above 100 Mbps and uplink rates above 50 Mbps.
The initiative, launched in May by telecommunications companies Alcatel-Lucent, Ericsson, France Telecom/Orange, Nokia, Nokia Siemens Networks, Nortel, T-Mobile and Vodafone, seeks to prove to the 3G Partnership Project (3GPP) the potential of LTE/SAE as a new standard.
The LTE/SAE Trial Initiative is divided into three main phases;
- Proof of concept
- Interoperability
- Trial
Joint testing, and reporting of ongoing results will continue out to the end of 2009, with initial LTE system deployments planned for the 2010 timeframe.
Between here and the 4G promised land are several hurdles. First, most carriers will need new radio spectrum to carry LTE services. Current 3G uses about 5MHz of spectrum for communication from the base station to the handset and 5MHz the other direction, while LTE will need about twice that much to deliver the promised speeds. Auctions in Europe for "3G extension" bands that could be used for LTE will probably be done by 2010, but current users may still be vacating it. In the U.S., parts of the 700MHz spectrum set to be auctioned early next year could be used for LTE.
