Jammer Signal

Some customers will mention such a question, a 6-story teaching building, each floor is about 1500 square meters, whether 1-2 high-power cell phone jammer can achieve mobile phone signal interference in the entire teaching building. Topsignaljammer Technology Co., Ltd. does not recommend using high-power mobile phone signal jammers to shield a 6-story teaching building. This idea is understandable. After all, the number of jammers used is small and it is easy to install.

Portable Mobile Phone Jammer Block GSM 3G 4G GPS WIFI Signal Why is it not recommended to use a high-power mobile phone signal jammer to interfere with a 6-story teaching building? The reasons are as follows 1. Choose a high-power mobile phone signal jammer to interfere with the entire teaching building. It is recommended to implement it in a building below the 4th floor. If the floor is higher than the 4th floor, the signal from the surrounding base stations will be transmitted to the teaching building, which will reduce a lot of obstructions. , the signal to the upper floor above the 4th floor of the teaching building will be higher than that of the lower floor. This will increase the difficulty of interference, and considering that the interference signal of the high-power mobile phone signal jammer takes into account the upper and lower floors, the installation position is generally not higher than 2 floors, which is about 6-9 meters. High, the installation difficulty increases, and safety is also a problem to be considered.

For teaching buildings below the 2nd and 4th floors, when configuring high-power mobile phone signal jammers, they also need to be installed in the front and back of the teaching building, and the number of configurations should be determined according to the strength of the mobile phone signal on site. Under normal circumstances, at least 2 sets of high-power mobile phone signal jammers are required. The cost of high-power mobile phone signal jammers is far higher than that of low-power mobile phone signal jammers.

Therefore, to sum up, it is not recommended to use a high-power mobile phone signal jammer in a 6-story teaching building. The most cost-effective way is to install a low-power mobile phone signal jammer in each classroom, and it can also be connected to the Internet for unified control and management through software.n Recently, a customer inquired whether the police jammer should be equipped with an omnidirectional antenna or a directional antenna when in use. The police frequency jammer is mainly used for auxiliary equipment used by the public security to deal with some special tasks. For example, the police jammer will be used in tasks such as gathering group events, temporary communication control, and arrest of suspects.

Police frequency jammers are generally portable and can be designed as a drag box or backpack. Under normal circumstances, police jammers are equipped with omnidirectional antennas. The advantages of police frequency jammer equipped with omnidirectional antennas are as follows: : 1. It is easy to carry. The omnidirectional antenna is basically a glass fiber reinforced plastic shell. When carrying, just put the antenna in the storage bag. It is best to use a special storage air box for the antenna, which takes up less space and does not need to worry about bumping. 2. Quick disassembly and assembly. When the police arrive at the mission site, they only need to connect the frequency band of the omnidirectional antenna to the frequency band interface of the police jammer, so as to tighten the omnidirectional antenna. It is also very convenient to disassemble. The antenna can be put into the storage bag. It is especially suitable for application scenarios when the police handle the above tasks.
