China Mobile Awards TD-LTE Contract to NSN

China Mobile has selected Nokia Siemens Networks for the deployment of TD-LTE in three cities by the end of 2012 as part of its large-scale, pre-commercial trial of TD-LTE.

Nokia Siemens Networks will deploy its TD-LTE 8-pipe radio and Flexi Multiradio Base Stations. In addition, Nokia Siemens Networks will help China Mobile with Circuit Switched Fallback (CSFB) technology testing in Hangzhou, a technique used to offer voice calls alongside TD-LTE services.

Nokia Siemens Networks noted that through its parent companies it has an over 20-year working relationship with China Mobile and was one of the first vendors to support the operator’s initial GSM network.

  • In September, Nokia Siemens Networks announced a new speed record for TD-LTE -- 1.6 Gbps. The previous record -- also set by NSN - was 1.3 Gbps.
  • The record was set using the company's commercial Flexi Multiradio 10 Base Station to receive and send data in simultaneous downlink and uplink connections, reaching an overall speed of 1.6 Gbps.  The test used 60 MHz of aggregated spectrum with an 8-pipe radio module that enables eight streams of uplink MU-MIMO.  The test was performed at the Nokia Siemens Networks lab in Arlington Heights, Illinois.
  • NSN also noted that the 8-pipe radio module design even exceeded the specs of LTE-Advanced, which requires only four streams of uplink MU-MIMO.
