When choosing a walkie-talkie, we are often faced with a choice between private and public walkie-talkies. So, what are the differences between private network walkie-talkies and public network walkie-talkies?, after reading this article, you should be able to have a preliminary understanding of it.
To understand the difference between the two, you can start with the following four aspects:
1. Coverage distance
The communication distance of DMR digital and analog private network walkie-talkies mainly depends on the power, the greater the power, the farther the communication distance. In the absence of any auxiliary equipment, the communication range is about 1~10 km. It is suitable for relatively few places. The communication coverage of the public network walkie-talkie is not limited, and the signal depends on the operator's established network. Calls can be made as long as there is a mobile phone signal.
2. Communication costs
When building a private network walkie-talkie communication system, a base station needs to be established. However, the construction of the base station requires a lot of manpower and material resources, and the construction project also needs to carry out the erection of relay equipment and the layout of related line projects. Therefore, the cost of private network walkie-talkie communication is much higher than that of public network walkie-talkie. The public network walkie-talkie only needs to rely on the public mobile network, so its cost is lower, and it is more convenient to use with fewer restrictions.
3. Communication function
The communication mode of the private network walkie-talkie is that one transmits the signal and the other receives the signal. The design is minimalist and the functions are relatively simple. The public network walkie-talkie is rich in design and powerful in multimedia communication. It usually supports voice, video, data transmission and other services, and can also be connected to WIFI, with value-added functions such as text messaging and GPS positioning.
4. Application scenarios
Of course, the use scenarios of the two types of walkie-talkies are different. With its special signal nature, the private network walkie-talkie is mainly used by staff in specific industries, such as public security and fire protection, construction sites, mines, etc., focusing on social benefits and providing more emergency communication and dispatching functions. The public network walkie-talkie pays more attention to economic benefits and is suitable for industries with a wide range of communication coverage, such as hotel management, supermarket property, etc. Of course, some industrial and commercial companies will also choose private network walkie-talkies to avoid communication blind spots and difficulties.
From a dialectical point of view, in fact, public and private network walkie-talkies have their own advantages and disadvantages. With the continuous development of market demand and technology, walkie-talkies have further evolved into an intelligent public-private integration model.
