DPI: Managing Data Traffic in LTE Networks
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.
