LONDON — Swedish telephone equipment supplier Telefonaktiebolaget L. M. Ericsson has demonstrated an end-to-end time-division duplex (TDD) LTE communication system at an event in Shanghai, China organized by China Mobile. Time division LTE is an alternative to frequency division duplex LTE which requires paired portions of spectrum for up- and downlinks.
The demonstration was based on ICs from ST-Ericsson NV (Geneva, Switzerland) and showcased mobile broadband applications such as video on demand (VOD) and video streaming using a live camera. It had previously been verified that the Ericsson TD-LTE solution has achieved a single user peak rate of 110-Mbps in the downlink. Ericsson did not state what data rates were achieved on the end-to-end demo.
The demonstration was performed with a USB dongle and Ericsson has successfully executed TD-LTE interoperability testing with ST-Ericsson, and testing with two other chipset/terminal vendors is expected to be finalized soon.
Ericsson (Stockholm, Sweden) is introducing a TD-LTE basestation based on the RBS-6000 multi-standard basestation that will be capable of a migration to LTE-Advanced.
"We will make every effort to support China Mobile in bringing revolutionary mobile broadband experiences to tens of millions of Chinese consumers in the near future," said Mats Olsson, president of Ericsson China & North East Asia, in a statement.
Available next year, ST-Ericsson's next generation modem is scheduled to support both versions of LTE, in addition to TD-SCDMA and HSPA+/EDGE. "Drawing on six years of LTE research and development, today's demonstration underlines ST-Ericsson's position as a frontrunner in the rollout of the next-generation of mobile broadband platforms," said Magnus Hansson, senior vice president and head of LTE and 3G modems at ST-Ericsson, in the same statement.
