System Profiles

System profiles set a basic level of common requirements that all WiMAX systems have to meet. To date, only one system profile has been defined and it is based on the IEEE 802.16-2004. A second system profile is currently being defined and will be based on the IEEE 802.16e-2005 and scalable frequency division multiple access. The first system profile is optimized for fixed and nomadic access; the second profile is for portable and mobile access, but also supports fixed and nomadic access [5].
The system profiles define the key mandatory and optional features that are tested in WiMAX products. The features listed as optional in the stan- dards may be tested as mandatory by the certification program; however, the certification does not include any new feature that is not included in the standards. For example, the fixed WiMAX profile based on IEEE 802.16-2004 only allows testing on equipment using point to multipoint operations up to 11 GHz, while IEEE 802.16-2004 equipment can operate up to 66 GHz.
