Abstract
A system and method for large building high bandwidth communication. An interface station is located on or near the building for providing high bandwidth communication between an external communication network and at least one, but typically several or many, free space optical distribution transceivers. Each free space optical distribution transceiver provides two-way optical communication utilizing beam splitters with at least two but typically several or many free space optical user transceivers within the large building. In a preferred embodiment each of several free space laser distribution transceivers are located on the top of a ten-story building and transmits information to free space laser user transceivers located on each of the ten stories of the building. Beam splitters are mounted on the windows of each floor to direct a portion of the laser beam from the roof-mounted transceiver to the user laser transceiver located on each floor. Once the signal is inside the building it can be distributed to informational appliances within the building by conventional methods. This system can provide one-way or two-way communication. Informational appliances can originate high bandwidth signals within the building, then transmit those signals first to free space optical user transceivers also within the building, then to the optical beam splitters outside the windows, then to the free space optical distribution transceivers exterior to the building, and finally to the building interface station and from there to the external communication network.
