AT PRR 1
Supplies of the equipment stopped.
The crucial element of the AT PRR1 radio system is a short-range transceiver operating in 2.4 GHz band with spread spectrum. The AT PRR1 provides voice and data communication. It is meant for operation units up to 30 persons requiring mutual communication (each to each) with rebroadcasting option. The transceiver is suitable both for communication among buildings and in open terrain, where the range extends up to 1000 m. Interception chances are very low. The transceiver is very resistant against narrow-band jamming. It is designed for full duplex communication in a group (network) without any further infrastructure and, with rebroadcasting, for communication between networks.
The personal role radio operates in 2.4 GHz frequency band using spread spectrum waveform - combination of time hopping, frequency hopping and OFDM (Orthogonal Frequency Division Multiplex). Designed for operation within groups of up to 30 users allows for full duplex communication in ad-hoc digital networks with no additional infrastructure required.
