LARGE-SCALE NETWORK HF RADIO WITH CONTINUOUS AREA RADIOACCESS Russian patent published in 2017 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: HF network comprises a multichannel stationary nodes territorial radio, consisting of spaced receiving and transmitting radio centers, software-defined subscriber radio terminals associated with the nodes of the network adaptive radio lines, stationary nodes zenith radio with service area up to 500 km, the main and backup control centers network, wherein the stationary support adjacent territorial radio access nodes located at the apices of adjacent spherical equilateral triangles for the other hand is not more than 3000 km along the great circle and have a radio zone with a radius of up to 3000 km each; adaptive radio subscriber line of a continuous band to a stationary reference nodes territorial radio access, trunk lines inter-node communication Are organized using the ionospheric mode 1F2, the program-defined network subscriber radio terminals contain an integrated navigation receiver for position determination, and the unit comprises sets of receiving and transmitting radio access antennas, as well as hardware and software complexes for ionospheric sounding, determining the spatial parameters of radio links and determining the working parameters Frequency bands providing the conduct of sessions with 1F2 mode.

EFFECT: increase the radius of the service area of the territorial unit of radio access up to 3000 km, with the exception of signal fading.
