9. IEEE group 802 is responsible for networking standards including Wireless MANs, where Working Group 16 (IEEE 802.16) has produced definitions for wireless MAN technologies. The original output from 802.16 was a technology that would operate in range of microwave frequencies from 10 to 66 GHz, this would encompass both licensed and unlicensed spectrum bands. An extension in 802.16a added operation in the range 2 to 11 GHz.In the higher frequency bands there is a requirement for a line-of-sight (LOS) between the transmitter and receiver necessitating prominent base station sites with traditional tower (mast) and antenna engineering. However, in the 2 to 11 GHz range operation is Near (or Non) LOS (NLOS). IEEE 802.16 uses OFDM technology to achieve aggregated data rates up to 124 Mbits/s within a 20 MHz channel, whereas 802.16a can support rates up to 70 Mbits/s. IEEE 802.16

62. Radio frames structure equally applies to TDD and FDD, resulting in maximal baseband processing commonalities. Superframe (802.16m) is a collection of consecutive equally-sized radio frames whose beginning is marked with a superframe header. Header consists of short-term & long-term system configuration. Frames are divided into subframes where each comprises an integer number of OFDMA symbols. Frames
