METHOD OF AVERAGE MULTICHANNEL ZONE NETWORK OF BILATERAL MOBILE AUTOMATIC RADIOCOMMUNICATION WITH TIME-DIVISION MODE OF RECEIVING AND TRANSMITTING MESSAGES Russian patent published in 2017 - IPC H04L27/22 

FIELD: radio engineering, communication.

SUBSTANCE: method of medium wave zone network two-way radio with a time division modes of reception and transmission of messages is to provide a medium wave a multi-zone network two-way mobile automatic radio time division reception mode and transmitting messages, which makes it possible in the same limited bandwidth to simultaneously communicate discrete reports a large number of subscribers, which are removed from each other over long distances and use VEHICLAR compact and wearable antennas that do not require high-rise above the surface of the Earth during communication sessions at distances that do not satisfy the requirements of the line of sight between the antennas transmit and receive radio stations. Radios have a relatively low-power transmitters and sending messages from them by signals with an extremely low velocity in order to increase the noise immunity as the communication channels, and to accommodate the maximum number of users in the frequency band allocated for the radio network. The signals from the subscriber stations are transmitted simultaneously through parallel channels at frequencies satisfying the requirement to ensure mutual orthogonality of these signals. The invention relates to radio engineering and is designed for simultaneous recto mobile automatic radio large number of subscribers using the parallel frequency-spaced radio channel in general limited bandwidth (e.g., SSB telephone communication channel) for transmitting digital messages within the zone, the boundary of which can be far beyond the line of sight between the antenna and the radio base station antennas peripheral stations. The base station has a relatively high power transmitter which can transmit messages over long distances at high speed sealing operation time and using conventional methods of manipulation techniques such bi-phase shift keying or rocker. This radio network can be used by Ministry of Emergency Situations to monitor units potentially dangerous objects, warning and alarm transmission.

EFFECT: enhanced communication reliability.
