A microwave integrated tele-radio-information system of multiservice radio-access with enhanced capacity UMDS-K comprises central and user stations, the central station comprises at least one transferring-receiving trunk comprising a transmitter, whose output through a duplexer is connected to an antenna; and a receiving trunk, whose input is connected through a duplexer to the antenna; the output – to a divider; the user station comprises a receiving-transmitting antenna, series connected to internal and external units; a Wi-Fi station is incorporated as the user station, which is connected to the internal unit and provides for access to IEEE 802.11. standard local network. Moreover, the central station comprises a FDMA access receive system of reverse channel (from the user station) comprising a sector antenna, a line channel, a reverse channel demodulator, a router or a switching device; moreover, the user station comprises technique for shaping and transmission of reverse channel (from the user station to the central station) – a traffic modulator, a user station router, a line trunk. |
