Abstract
A point-to-point, wireless, millimeter wave communications link between two stations at least one of which is a mobile station. A millimeter wave transmitter system operating at frequencies higher than 57 GHz with a tracking antenna producing a beam having a half-power beam width of about 2 degrees or less and a millimeter wave receiver also with a tracking antenna having a half-power beam width of about 2 degrees or less. In preferred embodiments each mobile station has a global position system (GPS) and a radio transmitter and both tracking antennas are pointed utilizing GPS information from the mobile station or stations. The GPS information preferably is transmitted via a low frequency, low data rate radio. Each millimeter wave unit is capable of transmitting and/or receiving, through the atmosphere, digital information to/from the other station at rates in excess of 155 million bits per second during normal weather conditions. In preferred embodiments actually built and tested by Applicants digital information has been transmitted at rates of 1.25 gigabits per second. Preferred communication links described here are millimeter wave links operating at frequencies of 71-73 GHz a…
