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 LTE
service.
