The intercom signal in the basement is not good. What should I do if I can't receive the intercom signal?

We often hear our customers come to inquire that the signal of their walkie talkie is not good, and there are often intermittent places. Is there any high-power walkie talkie that can solve the problem of walkie talkie communication.
   generally speaking, the higher the power, the farther the transmission, and the better the penetration effect. However, the walkie talkie is usually held close to the head of the person, and the state stipulates that the maximum power of the walkie talkie should not exceed 5W, which is harmful to the human body, especially not suitable for long-term use. What's the solution for the poor signal of the walkie talkie in the basement or large building? Today, Xiaobian will help you solve this kind of problem according to the poor signal of the walkie talkie in the basement
The intercom signal in the basement is not good. What should I do if I can't receive the intercom signal?
   A: the signal in the basement is not good
   the reinforced concrete wall of the basement of the general residential property is relatively thick, the attenuation of the walkie talkie signal is very large, and it is difficult to communicate with the upstairs in the basic basement. For such customers, if they originally have the relay station equipment, they will not increase the frequency resources and expand the coverage of the original base station; Through the signal test equipment, it is clear which areas of the basement have the signal blind area, and the antenna layout is increased in the blind area;
   if there is no relay station equipment, it is necessary to add relay station equipment. Take DMR / PDT digital relay station as an example, a digital relay station can use two channels, which needs to be configured according to the customer's own channel usage. Through coaxial cable and antenna, the whole basement is covered; then an outdoor antenna is added on the top of the building to ensure good signal in a certain area of the building.
   B: the intercom signal inside the building is not good
   for clubs, KTV and other places with large floor area, because of the large area and many decorated walls, the interphone signal is poor. For less channels, a rd620 wall mounted relay station can be arranged. This relay station has a built-in power duplexer, which can be used only by hanging on the wall and connecting with the antenna, and can cover 100-200 meters of floor area.
   C: walkie talkie signal is not good in zero time places
   for example, how to deal with some emergencies, high-end conference activities, and poor interphone signal? We recommend the use of embedded compact design, with the thickness of 41mm and the weight of less than 3kg. Built in duplexer: optional built-in Mini duplexer, more compact internal space, smaller size. For outdoor construction sites, field activities, etc.
   from a practical point of view, lovers do not always need to receive two channels at the same time. In many cases, they only need to wait for one channel, and the other channel is cumbersome. Therefore, they are more likely to choose the dual band and dual reception radio stations that can receive two channels or one channel freely. At present, most of the imported high-end hand sets on the market have such humanized design.
