What is a public network intercom?

In recent years, I believe everyone is familiar with the term public network walkie-talkies. Compared with traditional analog walkie-talkies and professional digital walkie-talkies, what are the advantages of public network walkie-talkies? Let’s talk about some common problems with public network walkie-talkies below!

Q1: What is a public network intercom?

Public network walkie-talkies, also called national walkie-talkies, transmit voice signals based on base station channel time slots. Its principle is very similar to whatapp, but it is better than whatapp to achieve real-time interoperability. Compared with traditional walkie-talkies, public network walkie-talkies also have more functions, including the most basic nationwide unlimited distance walkie-talkie, group call/single call/group call, which can break through the distance limit, and can be used nationwide as long as both parties have a network. interconnection.

Q2: What are the characteristics of public network intercoms?

Public network intercom uses the operator's 4G network to make real-time calls. As long as there is an operator's signal, the call can be made. In theory, it can realize national intercom and global intercom. Compared with traditional radio hard intercom, it has the following Features:

1. The distance is not limited, and within the 4G signal coverage area, you can make intercom calls freely;

2. Digital signal, clear sound quality and loud sound;

3. The call confidentiality is strong and there will be no leakage of secrets due to the same frequency;

5. Low construction cost, relying on public mobile networks and no need to deploy base stations;

6. Users do not need to obtain a radio qualification certificate and are more suitable for ordinary people.

As the industry continues to explore and develop towards the integration of broadband and narrow, and the combination of dedicated and public services, the public network market has gradually begun to mature. In recent years, the sales volume of public network walkie-talkies has maintained continuous growth, and application scenarios have also been continuously enriched; bringing better benefits to users This is an important reason why more and more people are beginning to accept and fall in love with public network walkie-talkies!
