Can the intercom be used without a signal?

As long as the place where there is no signal is not a vacuum and there is a frequency, the walkie-talkie can be used.

Interphones use radio waves to transmit voice signals. There is no need for an exchange. It is a one-to-one working mode, that is, one transmits a signal, and the other receives a signal, as long as two (or more than two). The two-way radio works on the same frequency, and the positions are all within the signal transmission range.


The higher the power of the walkie-talkie, the farther it is transmitted, the better the penetration effect will naturally be. However, when the walkie-talkie is used, the distance from the head of the person is shorter. It is harmful, so it is not suitable for long-term use.

Walkie-talkies cannot be used normally. Usually the manual will explain the specific value of the communication distance, but generally refers to the area where the field of vision is wide, that is, the distance that can be reached without obstacles. Two people cannot exceed this established range. If it still cannot be used normally within the range, there are the following reasons:

1 Obstacles in the surrounding environment, such as high-rise buildings, trees, outdoor billboards, etc., will absorb and obstruct the radio waves emitted by the radio, directly affecting the transmission distance of the signal.

2 Excluding the impact of various anti-interference capabilities inside the walkie-talkie itself, in the densely populated cities, signal interference caused by other walkie-talkies, unlimited equipment, and electrical equipment is also prone to be caused by the interference.

3 Different weather, temperature and even day and night will affect the transmission of the signal.

Above, it is recommended that users can measure according to their actual needs, whether they are purchasing or using, and choose the appropriate type of equipment.
