1. A point-to-point gigabit millimeter wave communications system comprising:

  • A) a first millimeter wave transceiver system configured to transmit and receive at frequencies greater than 57 GHz and located at a first site capable of transmitting and receiving to and from a second site through atmosphere digital information at rates in excess of 1 billion bits per second during normal weather conditions, said first transceiver comprising an antenna producing a beam having a half-power beam width of about 0.36 degrees or less, said antenna being supported with a rigid support providing beam directional stability of less than one-half said half-power beam width during 90 miles per hour steady wind conditions, B) a second millimeter wave transceiver system configured to transmit and receive at frequencies greater than 57 GHz and located at said second site capable of transmitting and receiving to and from said first site through atmosphere digital information at rates in excess of 1 billion bits per second during normal weather conditions, said second transceiver comprising an antenna producing a beam having a half-power beam width of about 0.36 degrees or less, said antenna being supported with a rigid support providing beam directional stability of less than one-half said half-power beam width during 90 miles per hour steady wind conditions, C) a backup transceiver system operating at a data transmittal rate of less than 155 million bits per second and configured to continue transmittal of information between said first and second sites in the event of abnormal weather conditions, and D) a network communicating with one of said first or second transceiver systems and providing high-speed communication to each of a plurality of users at data rates of 10 Mbps or greater.
