TIME DIVISION METHODS IN NETWORK RADIO CHANNELS. RF PATENT ¹ 2350024

The invention can be used at different networks creation for data and multimedia transmission both for national economy and special purposes.

The proposed way of network organization with time division channels minimizes uncontrolled broadcasting of subscriber stations and provides guaranteed quality of subscribers service. Unified radio set (URS) for network construction by this method is offered. URS prototypes (“Topaz-V” and “Voskhod”) have been developed and tested. The samples are made on base of new processors and programmed logical integrated circuits which are realized under patent ¹ 2350024. URS include two independent transceiving modules joined by common control, switching and coupling system with terminal data equipment. URS provide zone and radio relay systems creation both of stationary and mobile variants. The unified radio sets operate in frequency range (1.35–1.85) GHz with channel bandwidth 54 ÌHz on directional and non-directional antennas. Maximal rate of each independent module group channel is 10, 24 Ìbit/s. The result is noise-immune and reliable connection in time division channels system. It also allows subscriber guaranteed resource during long period of time. The invention by patent ¹ 2350024 is in the data base «Perspective inventions».
