A system and method for networked high-speed data communication through free space is described. The system includes one or more central networks, which contain one or more lasers modulated with high-speed data to illuminate with laser light areas surrounding the central network in which are located one or more user networks. The laser from the central network generates a radiation pattern that is sectored into horizontal and vertical sectors, and further divided into channels for each wavelength. Data coming from the user networks modulates a laser, which is transmitted as a collimated beam through free space back to the central network where it is received. Communication can be point-to-point, point-to-multipoint, multipoint-to-point, or multipoint-to-multipoint, and the point-to-multipoint communication can be broadcast, simulcast, or multicast. |
