Functions, advantages and disadvantages of public network walkie-talkies

The advantage of public network walkie-talkies is that they can communicate over any distance. Unlike traditional walkie-talkies, which rely on transmission power, public network walkie-talkies rely on the signal of the network operator.

Public network intercoms are also called card intercoms and IP intercoms. Depending on the corresponding operator signal used, it can be called 2G walkie-talkie, 3G walkie-talkie, or 4G walkie-talkie.

Public network walkie-talkies are compared to private network walkie-talkies. Private network walkie-talkies refer to walkie-talkies that need to build a self-built signal channel and use the self-built signal channel to communicate. Public network walkie-talkies refer to walkie-talkies that use the operator's network to make calls. The transmission distance of private network walkie-talkies is generally a few hundred meters to several kilometers, and the communication distance is limited. Public network intercoms can make calls wherever there is an operator's signal. In theory, they can achieve nationwide and global intercoms. Compared with private network walkie-talkies, it has the following characteristics:

1 Cost-effective to use
Compared with private network walkie-talkies, public network walkie-talkies need to achieve long-distance communication. They do not need to set up relevant repeaters and lines, and can save a lot of manpower and material resources.

2 The construction period is shorter and timeliness is better

Compared with private network walkie-talkies, if a public network walkie-talkie is used to achieve long-distance communication, it does not need to erect cables and directly uses the telecommunications operator's network, which can save a long construction period and achieve long-distance communication faster.

3 Good adaptability
Due to the influence of topography, weather and other external factors, some places are not suitable for erecting cables and repeaters, so private network walkie-talkies may not be suitable at this time, while public network walkie-talkies do not have this concern

4 Good scalability
In our life, we often need to add new equipment terminals based on an existing communication network. If we use a private network, we may need to destroy some original communication lines, but if we use a public network intercom, we It is easy to achieve by re-dividing the groups in the background

What are the disadvantages of public network walkie-talkies?

1. In places where there is no network or the network signal is not good, this walkie-talkie cannot play its role.

2. Different suppliers may correspond to different public network platforms. The public network platform is limited by the brand and the cooperative operators, and a certain platform fee needs to be paid every year.
