As a wholesale oem long range walkie talkie exporter, factory, supplier and manufacturer, we mainly discuss how to choose a remote walkie-talkie.
Factors should be considered when purchasing a walkie-talkie
- Generally, the communication distance of walkie-talkies is about 1-3 kilometers, so ordinary civil walkie-talkies can meet the application requirements of most occasions.
- If you need a longer talking distance, such as within 2-10 kilometers, you should consider buying a high-power professional walkie-talkie.
- If you need an effective distance of 10-30 kilometers, you need to install a repeater to expand the distance of the call.
- For the need for longer-distance communication (more than 30 kilometers), you can consider public network trunking walkie-talkies. The biggest advantage is that long-distance communication can be realized without the need for hardware installation and networking; intercom calls in any two places in the country are not a problem, and it can also be used to achieve effective communication between the company and the personnel on business at any time .
For the selection of analog long range walkie-talkies, you need to select the appropriate frequency range according to your needs.
U section: 400-470MHz;
V segment: 136-174MHz;
Police band: 350-390MHz
The electromagnetic wavelength of the U/V segment walkie-talkie is different, and the loss during transmission is also different. There are many buildings in the city, and it is better to use U-segment intercom; if the environment is relatively open, such as the sea, the wilderness, etc., the V-segment intercom is relatively better.
- Walkie-talkies are widely used in commerce, industry, etc., such as hotels, guesthouses, KTV, property, clubs, construction sites, shopping malls, supermarkets, etc.
