The wireless multipoint network module, shown in 

, also referred to as a subscriber unit (SU), 

provides a high-speed broadband fixed wireless radio-frequency (RF) link between each subscriber site 
and a single headend site. This link delivers full-duplex data in the licensed MMDS band (2.500 to 2.690

minimizes the effects of fading, uses two wireless transverters at each site, with each transverter 
connected to its own antenna. (See
