802.16e is a technical wireless standard commonly known as Mobile WiMAX. Compared to earlier versions of WiMAX, 802.16e allows users to be on the move (such as in a car or on a train) while maintaining an active connection.
WiMAX technology provides the equivalent of broadband speeds without the need for cables, and service coverage can extend over an entire city, region or even a whole country.
Access to the WiMAX wireless service is subject to a monthly subscription and it requires the use of a dedicated WiMAX modem, which is usually supplied for free by the operator.
WiMAX technology allows for data transfer speeds of up to 75Mbps, but in reality they tend to be a lot lower than that, at around 1-10 Mbps tops.
