The key difference between 4G and 5G is speed — 5G is expected to be much faster than 4G while offering lower latency and better bandwidth.

Speed with WiMax in theory should be close to 4G over LTE, but this particular implementation is supposed to be awful-- 3.5G speeds at best for the network as built, and coverage is spotty.

What fleets need to know about the sunsetting of 2G and 3G technologies and the upcoming jump to 5G.
