POC walkie-talkie knowledge solution

1. Can POC walkie-talkies communicate with professional conventional walkie-talkies?

cannot communicate. POC walkie-talkies rely on mobile cellular communication base stations and Internet platforms all over the world to realize a series of information processing and connection services for intercom voice. The call delay and quality depend on the transmission capability and signal processing capability of the platform; from the working frequency of the wireless terminal For example, work in different frequency bands and technical processing regimes.

2. Can the POC walkie-talkie do short-distance intercom calls without a SIM card?

unable. The SIM card is a necessary means for terminal equipment to use the mobile network to register, log in and manage groups. Without it, there is no ownership and soul of the information, so naturally it cannot be used, let alone intercom.

3. Does the POC walkie-talkie have more functions and are easier to use than the walkie-talkie?

It cannot be generalized. It needs to be appropriately selected according to the specific situation, such as considering the subsequent use costs, the coverage of mobile signals in the area of use, the local radio interference, and the communication requirements and complexity of large buildings and underground areas in the area. Consult relevant professionals for selection. Ideal purchase solution. The POC walkie-talkie is a derivative function built on the cellular mobile platform, with relatively feature-rich additional functions, but cannot work without cellular network support. Professional walkie-talkies have stronger independent networking capabilities, and are irreplaceable in short-distance, anytime, anywhere intercom and professional network communications and emergency communications.

4. Cost issues

POC walkie-talkies require platform management and service support fees. Generally, it is more likely that the service provider will pay the usage fee for one year or regularly, otherwise the service will be stopped when it expires. The traditional walkie-talkie is put into use at one time, free to use, and more flexible and convenient.

5. POC walkie-talkies cannot replace private network walkie-talkies

The public network PoC intercom cannot completely replace the traditional private network intercom system. Under special circumstances, the public network communication facilities are often severely damaged due to irresistible reasons such as earthquakes and floods, resulting in the loss of the POC intercom. Mobile platform support and lose the intercom function. Therefore, when carrying out emergency rescue or performing emergency tasks, small-scale rapid application and the private network cluster system of relevant command departments still play an irreplaceable role.
