RT3 DMR digital radio

The digital intercom reduces the channel spacing to 6.25kHz again

It enables the 12.5 kHz channel to support two channel independent calls. Improve the spectrum utilization, which is a solution to the problem of frequency congestion, with long-term significance.

Change the control signal with the communication distance increases and reduce the weakness

One of the reasons for the superiority of the digital machine at the furthest edge of the transmission range is that it has invested a great deal of effort in the choice of forward error correction and cyclic redundancy check coding when the standard is developed. These encoders enable the receiving device to detect and automatically correct for transmission errors by analyzing the insertion bits in the information (for the receiving device to check for errors). Thus providing a more reliable audio in a larger total area.

Excellent audio performance

Digital technology provides better noise suppression and maintains superior voice quality over analogue over a wider range. Through the use of encoders and other techniques, digital processing can filter out butterflies and reconstruct signals from degraded transmission signals. Users can more clearly hear all calls.

Improve and improve voice and data integration

Compared with similar integrated analog voice and data systems, digital radio can provide GPS, weather, information transmission and other better data transmission and interface functions, so that more data applications can be integrated into the same two-way wireless communication base station structure In the integration of voice and data services more complete and more convenient.

 

The digital machine provides better call confidentiality

Digital machines have information carrying characteristics, which provides for the convenience of voice encryption. Digital radio in the communication signal in the specific digital code attached to the signal received only after the identification of the digital code can be removed. This way high precision, easy handling, programmable.
