MILLIMETER WAVE COMMUNICATION LINK

摘要

A point-to-point wireless gigabit millimeter wave communications link is disclosed. Preferred embodiments provide a back-up link. In other embodiments, each of two communicating antennas (220) is equipped with a telescopic camera (200) connected to a processor programmed to recognize landscape images. The processors are programmed to remember the pattern of the landscape as it appears when the antennas are aligned. Each of the cameras (200) then view the landscape periodically or continuously and if the landscape in view changes by more than a predetermined amount a signal is provided to indicate a misalignment. An operator can then take corrective action or alternatively the antenna system can be configured for remote or automatic realignment based of feedback from the camera (200). In a preferred embodiment, the antennas are initially aligned by substituting a narrow band oscillator power source for the signal transmitting electronics associated with a first antenna and a power detector is substituted for the signal receiving electronics associated with a second antenna.
