Public network intercom is a wireless intercom device that uses existing mobile communication networks(such as 3G/4G/5G and WiFi) to achieve remote communication.It breaks through the distance limit of traditional intercoms.As long as there is an operator signal,calls can be made.In theory,intercoms can be made nationwide and globally. ‌

The working principle of public network intercom is to digitize and compress the voice and send it through the existing public mobile data network.This device usually has a screen,simple operation,clear sound quality and loud voice during the call,strong call confidentiality,and low call cost.Compared with traditional private network intercoms,public network intercoms do not need to build their own signal channels,and are more flexible and convenient to use.

The advantages of public network intercoms include:

‌National and even global coverage:calls can be made as long as there is an operator signal.

‌Clear sound quality:The sound quality is clear and the voice is loud during the call.

‌Simple operation:Most public network intercoms have screens and are easy to operate.

‌Low call cost:The call cost is relatively low.

‌Flexible networking‌:You can create groups as needed,making work scheduling more convenient.

The disadvantage of public network walkie-talkies is that they rely on the network and need to rely on the operator's network to make calls,so the use effect may be affected when the network is unstable.
