Ericsson Takes LTE to the Street

From PC World: Ericsson has managed to achieve rates in excess of 100M bps (bits per second) with next-generation mobile technology LTE (Long Term Evolution) during recent field trials.

LTE is pitched as a successor to the 3G (third generation) mobile services such as the European UMTS (Universal Mobile Telecommunications System) and similar wide-band CDMA (W-CDMA) services.

Ericsson's goal in the field trials was to show that LTE works all the way from the base station to the terminal. "It's always easy to say that you can get a certain speed in a lab environment, but here we have used real antennas and real distances to the terminals, and also in a moving vehicle," said Lars Tilly, head of research at Ericsson Mobile Platforms.

Using four transmit streams (the maximum number supported in the LTE standard), four receive antennas and bandwidth of 10 MHz, the measured peak rates exceeded 130M bps. This translates into approximately 260M bps, given the maximum bandwidth of 20 MHz, according to an article in Ericsson Review.
