The difference between talkie walkie digital and analog walkie talkie
Traditional mode walkie-talkies can only support communication in a single mode, and talkie walkie digital can simultaneously receive digital and mode signals to achieve digital-analog compatible coexistence, ensuring a smooth transition from analog to digital, and greatly reducing customer investment costs.
The differences between digital walkie-talkies and analog walkie-talkies are as follows:
1.The traditional analog walkie-talkie is a communication mode in which voice, signaling, and signals are modulated on the walkie-talkie carrier frequency in a continuous wave manner, and after optimization processing such as amplification. It has the advantages of mature technology, complete system and relatively low cost.
2. Talkie Walkie Digital is a digital communication mode that uses digital signal processors to optimize the digitization of voice signals with a specific digital coding method and a specific baseband modulation form.
A.The first is to make better use of spectrum resources. Similar to cellular digital technology, digital walkie-talkies can load more users on a specified channel and improve spectrum utilization. This is a solution to frequency congestion.
B.The second is to improve call quality. Because digital communication technology has an error correction function in the system, compared with analog radios, it can achieve better voice and audio quality in a wider range of signal environments, and it will receive less audio noise and sound. Clear.
C. The last point is to improve and improve the integration of voice and data, and to change the weakness of the control signal 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 the same two-way wireless communication base station structure for voice and data services. Integration is more complete and convenient.
