Digital Radio
Peer-to-peer communication with FDMA and the Digital signal advantage
When compared to a TDMA (Time Division Multiple Access) 6.25kHz equivalent system, the FDMA (Frequency Division Multiple Access) enables "peer to peer" communication between radios in 6.25kHz digital mode. It ensures communication with no reduction in channel capacity, even if a repeater site is not available, or goes down.
When comparing digital with analog FM, the audio quality of analog FM gradually deteriorates with static noise as the distance increases. On the other hand, the digital audio provides noise-less, stable audio for longer until the fringes of the communication range.
