Digital two-way radios operate by encoding, transmitting, and decoding sound waves. The signal is represented by binary numbers—1s and 0s—that correspond with voltage values. Inside the radio, the vocoder—an analysis/synthesis system wont to reproduce human speech— encodes the transmission. The radio sends the signal, and therefore the vocoder on the receiving end decodes it.
In addition, the software in digital radios contains an algorithm that recognizes the difference between voice and ground noise and cancels undesirable audio for clearer, cleaner sound quality.
By proactively transitioning to digital radios now, your organization will enjoy greater benefits immediately, and your fleet is prepared for the high-efficiency innovations coming in the future.
