Abstract – The evolution of cdma2000 1xEV-DO systems to multi-carrier EV-DO (supported by 1xEV-DO Revision B) is discussed in this paper. Multi-carrier EV-DO offers a backward compatible upgrade to leverage existing 1xEV-DO networks and terminals. It allows a software upgrade to multi-carrier EV-DO using 1xEV-DO Revision A base station hardware.
