air interface,of interoperable,fixed point-to-multipoint,broadband wireless access systems,.The specification enables transport of,data,video,and voice,services.It applies to systems operating in the vicinity of,30 GHz,but is broadly applicable to systems operating,between 10 and 66 GHz,.,8,IEEE 802.16 Standards,802.16,MAC+,10-66GHz PHY,802.16a,2-11GHz
