LTE is already implemented in many countries but still in the early stage.
LTE is also considered the competitor to WiMAX.
LTE promises to provide theoretical peak download rates of up 100Mbps (rates with varies based on environment etc) and peak upload rates of up to 50Mbps.
LTE is a better technology than wimax becauste LTE will make people free from the burden of having to find a WiFi hotspot (Wimax) when they are on the road.
As long as you have an LTE modem, LTE subscribers can connect to the internet anywhere in the service provider's coverage area!
