Advantages of digital walkie-talkies over analog walkie-talkies

1. The traditional analog walkie-talkie is a communication mode in which voice, signaling, and signals are modulated to the walkie-talkie carrier frequency in a continuous wave mode and then amplified and optimized. It has the advantages of mature technology, complete system, and relatively low cost.

2. The digital walkie-talkie is a digital communication mode that digitizes the voice signal, uses a specific digital coding method and a specific baseband modulation form, and uses a digital signal processor for optimization.

First of all, you can make better use of spectrum resources. Similar to cellular digital technology, digital walkie-talkies can load more users on a designated channel and increase spectrum utilization. This is a solution to frequency congestion.

Second, improve the quality of calls. Because digital communication technology has the function of error correction in the system, compared with analog walkie-talkies, it can achieve better voice and audio quality in a wider range of signal environments, and it will receive less audio noise and more sound. Clear.

Third, improve and improve the integration of voice and data, and change the weakness of the control signal that decreases as the communication distance increases. Compared with similar integrated analog voice and data systems, digital walkie-talkies can provide better data processing and interface functions, so that more data applications can be integrated into a two-way wireless communication base station structure for voice and data services The integration is more complete and more convenient.
