光学无线通信系统或称自由空间激光器技术 ,是用一束激光穿透空气 ,而不是沿着玻璃纤维把信号发送给若干距离外的接收器的无线通信技术。把一台激光收发两用机连接到网络上 ,把该装置瞄向另一幢建筑物中的收发两用机 ,即可完成两个局部网络之间的连接。每一端的收发两用机都是 An optical wireless communication system, or free-space laser technology, is a wireless communication technology that uses a laser beam to penetrate the air instead of transmitting signals along a fiberglass to a number of receivers outside the range. Connecting a laser transceiver to the network and targeting the transceiver in another building completes the connection between the two local networks. Both ends of the transceiver are
