WiMAX is a radio technology which was developed to transfer data across distances of up to 50 km at transmission rates of at most 70 Mbit/s. It is primarily used to provide broadband Internet access.
From a technical viewpoint, WiMAX closely resembles WLAN systems (Wireless Local Area Networks). By using suitable modulation and coding methods, however, entire regions can be covered which is not the case with WLAN which can cover a range of only several hundred metres, depending on local conditions.
As in the case of mobile networks, the base stations, each of which delineate a cell, create WiMAX networks. In such a cell, WiMAX reception enabled terminals (e.g. computers) can be used in a stationary or also mobile mode.
In view of their radiated power of more than 10 W (EIRP), the base stations of WiMAX networks are monitored by the Federal Network Agency for their adherence to the limits specified to protect persons exposed to electromagnetic fields.
