Claim Text:
1. A wireless system for backhaul applications, wireless Ethernet replacement applications and broadband wireless drop applications, the system comprising: a central broadcast radio having an adaptive antenna array; one or more terminal broadcast radios that communicate wirelessly with the central broadcast radio, each terminal broadcast radio having an adaptive antenna array; wherein the central broadcast radio and the one or more terminal broadcast radios communicate using one or more links formed by the adaptive antenna arrays that are capable of using a non-line of sight propagation channel; and a beamforming network coupled to the adaptive antenna arrays that performs time-space adaptive processing of each link to optimally equalize a multipath channel to enhance signal to noise ratio, the beamforming network using extreme interference cancellation that inverts a channel from each adaptive antenna in the adaptive antenna array and eliminates interference between the channels from each adaptive antenna in the adaptive antenna array, by directing spatial nulls in the array antenna pattern in the directions of all interfering terminal broadcast radio forming a beam peak in the direction of the desired terminal broadcast radio.
