Huawei today announced the successful completion of a commercial test for LTE to CDMA evolved, High-Rate Packet Data (eHRPD) optimized handoff. eHRPD means the evolution and improvement of the original CDMA EV-DO network.
eHRPD acts as a bridge from CDMA to LTE by ensuring service continuity while protecting existing operator investment. In the initial stage of LTE deployment, network coverage is mainly concentrated to the hotspots. When users move outside of the LTE network, their mobile broadband data service is seamlessly handoff to the Evolution-Data Optimized (EV-DO) network, ensuring a good experience. This is a key function for all the hundreds of CDMA operators who are expanding their networks with the 10 times more capable LTE service. Without a smooth handover between LTE and CDMA the end-user will have a poor data service experience.
