Abstract

A point-to-point, wireless, millimeter wave trunk line communications link at high data rates in excess of 1 Gbps and at ranges of several miles during normal weather conditions to connect a local communication network through a SONET aggregation unit to a high speed fiber-optics network. In a preferred embodiment a trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same spectrum.

Claims25

Dependent claims

A SONET-based communication system including at least one millimeter wave wireless link comprising:

A) a first millimeter wave transceiver system located at a first site capable of transmitting to and receiving information from a second site through atmosphere digital information at rates in excess of 1 billion bits per second said first transceiver comprising an antenna producing a beam having a half-power beam width of about 2 degrees or less,
B) a second millimeter wave transceiver system located at said second site capable of transmitting to and receiving information from said first site digital information at rates in excess of 1 billion bits per second said first transceiver comprising an antenna producing a beam having a half-power beam width of about 2 degrees or less
C) at least one local communication network,
D) a high speed fiber-optic network, and
E) a SONET aggregation unit;
wherein communication is provided between said at least one local network and said high volume fiber-optics network via said first and second transmission systems and said aggregation unit.
