Possibilities of using radio stations with speech transmission function for internal affairs bodies by Push-to-talk over cellular, Poc

Abstract

The article discusses current issues of introducing promising models of radio communications into the activities of police departments. The use of completely new generation radio stations with speech transmission function Push-to- Talk over Cellular, PoC will allow you to work in widely available public networks and provide almost instantaneous communication at the touch of a button. This is the optimal choice for employees of operational units. Thanks to the algorithm used to suppress background interference arising from feedback between closely located radio stations, unpleasant noisy sounds do not occur when using two terminals at a distance of less than 3 meters from each other.
