发明名称 Multipoint-to-point wireless system using directional antennas
摘要 A multipoint-to-point wireless System using directional antennas in an indoor environment. Optical pulses in an asynchronous transfer mode network may be converted into radio pulses, which are transmitted by a radio transmitter to a radio receiver, and then may be reconverted into optical pulses. Transmitter antennas having predetermined beamwidths are used and positioned within the indoor environment for transmitting data signals at a selected carrier frequency. A receiver antenna with a predetermined bandwidth is positioned within the indoor environment for receiving data signals transmitted at the selected carrier frequency. Amplitude Shift Keying (ASK) is used so that the output between transmitted data packets is zero, thereby allowing other users to utilize the system during the gap between the packets.
