Nortel and LG Complete First Handover Between CDMA and LTE

Nortel and LG Electronics completed the first 3GPP standards compliant active handover of a data transmission between a LTE network and a CDMA network. The demonstration showed that online activities like video downloads, web surfing, and VoIP calls can be maintained when a mobile data user moves between LTE and CDMA coverage zones.

The test by Nortel and LG Electronics successfully demonstrates standards-compliant CDMA-LTE interworking. This enables idle mode handover between CDMA and LTE, and active mode handover from LTE to CDMA leveraging device assisted, network controlled functionality. The demonstration was conducted over 700MHz spectrum using Nortel CDMA Evolved High-Rate Packet Data (eHRPD) 1xEV-DO and Nortel Long Term Evolution (LTE) solution with LG Electronics' dual-mode CDMA-LTE M13 terminal. The M13 terminal is a test device created with commercial grade components that will form the basis for a consumer device which is expected to be available in 2010.

The handover between LTE to CDMA networks was completed in a Live-Air Drive Test at Nortel's Research and Development centre in Ottawa, Canada.

Nortel's CDMA business and LTE Access assets are the subject of an asset sale agreement with Ericsson.http//www.nortel.com
