The PR20 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). It is primarily designed for operation groups of up to 30 persons (but it also supports networks with unlimited number of participants) allows for full duplex communication in ad-hoc digital networks with no additional infrastructure required. Automatic rebroadcasting (packet routing), space diversity transmission and reception, high speed data transmission, long battery life and relay to higher level network are standard features.
