802.11af Training

802.11af training course covers TV White Space (TVWS), new PHY and MAC considerations, Software Defined Radio (SDR),Cognitive Radio (CR) technology, Geographic Sensing, and coexistence between heterogeneous systems.

IEEE 802.11af or White-Fi and Super Wi-Fi training course covers wireless local area network (WLAN) operation in TV white space spectrum in the VHF and UHF bands between 54 and 790 MHz.

Learn about 802.11af Physical layer, MAC layer, multiplexing (OFDM) scheme, Space–time block code (STBC), multi-user (MU-MIMO) operation, Data rates, Theoretical throughput for single Spatial Stream, supported MCS, Spectrum regulation and Comparison with other 802.11 standards such as 802.11ax , 802.11az, 802.11ay, 802.11ac and 802.11ah.

802.11af AKA White-fi is a 802.11/Wi-Fi technology within the TV unused spectrum, or TV white space. IEEE 802.11af uses TV white space and the overall system must not cause interference to the primary users.
