A pretty big landmark for lovers of CDMA and LTE networks (that'd be Verizon, for sure) occurred recently. LG and Nortel completed the first data handoff between LTE and CDMA networks, and they did so in a way that is standards-compliant. That's kinda important for the obvious reasons.
In geek speak:
The test by LG and Nortel successfully demonstrated the feasibility of 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 LTE solution with LG’s 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.
