It would seem, for what a person walkie-talkie into a car, if everyone around is using cell phones? Even many taxi drivers and truck drivers use them as the main mode of communication. At the same time, all special purpose vehicles are equipped with walkie-talkies. Police cars, ambulances, fire brigades communicate with these transceiver devices. People who regularly go out hunting and fishing or are engaged in extreme sports also prefer this method. In particular, special radios for skiers, private security companies and construction companies are produced.
In order to explain this situation, it must be said that the principle of the operation of radio communication differs significantly from the cellular mechanism. Everyone knows that cellular communication is carried out with the help of special antennas, which are located on the territory of the country. Where there are no "towers", there is no connection. Communication by radio is carried out at a certain frequency. A few years ago, the radio was installed in the car only with the permission of the competent authorities. Of course, this was inconvenient and created serious problems for those who wanted to use this connection. However, we must admit that the reasons for such limitations were.
The fact is that on the most popular frequencies communications have been built in aviation, on the railway, in the emergency services and in other spheres. Imagine that a walkie-talkie is installed in an ordinary citizen's car, and he establishes a connection with someone. And at this time the airliner comes in for landing, and the pilot is negotiating with the dispatcher. The situation is regular, but very responsible. And then an extraneous citizen intervenes in the service dialogue, who also communicates with his subscriber. Of course, such interference distracts the pilot, and he can commit wrong actions. That is why very few people received radio sets.
Some time ago, a specific frequency band was specifically allocated for free use. In another way, it is called a civilian range. On one of the frequencies tuned radio, which are freely sold in specialized stores. Anyone can buy this device and use it safely. And he will not interfere with the services mentioned above. Today, more and more people are asking themselves how to choose a radio so that it works reliably. Of course, to answer this question, you need to clearly determine for what purposes you need a walkie-talkie in the car.
For those who are engaged in transportation, more powerful devices are required. It must be borne in mind that the signal in the air can be distorted and damped. Even a multi-storey house creates a significant obstacle for its passage. When a walkie-talkie is installed in the car, it is necessary to select and install a reliable antenna. The quality of communication depends on its size. The installation itself requires certain skills. When the antenna and radio are mounted, it is advisable to test them. In practice, it happens that on the open space the connection operates steadily at a distance of tens of kilometers. And in urban conditions, five hundred meters can be insurmountable.
