Long Term Evolution (LTE) is the true heir to the 4G moniker and a pure evolution of today’s 3G wireless networks. Plans for offering LTE’s 100 Mbps+ data rates already have been announced by the majority of wireless operators, and the race to be first has begun.

LTE offers the promise of a pure, all-IP converged core network instead of the separate circuit- and packet-switched networks used in current cellular systems. At the same time, with “all-IP” networks, wireless carriers have to prepare for all of the challenges that today’s Internet service providers (ISPs) face.
