How to choose a mobile phone signal jammer in an open environment of 300 × 600 meters
The construction site environment of 300×600 meters, such an environment, when choosing a mobile phone signal jammer, mainly consider the following factors, and then you can choose what kind of mobile phone signal jammer.
First of all, it depends on the strength of the mobile phone signal in the construction site environment. If you are near the construction site and look around, if you can see the base station of the operator within the line of sight, it means that the signal strength from the base station to the construction site will not be very weak. Unless the distance is more than one kilometer, there is a base station within 500 meters, and there is no obstruction between the base station and the construction site, then the signal from the base station to the construction site will be relatively strong, which will seriously affect the shielding range of the mobile phone signal shielding device. If you want a good shielding effect, you must use a high-power mobile phone signal blocker, or increase the number of mobile phone signal blockers.
Secondly, pay attention to the surrounding environment. If the surrounding area is not a densely populated area, then there is no need to consider the problem that the coverage of the mobile phone signal jammer is too large, which will affect the residents' mobile phone signals. You can use an omnidirectional antenna to match, which can slightly reduce the number of mobile phone signal shielding devices. Otherwise, it is necessary to use a high-power mobile phone signal jammer with a directional antenna to cover the 300×600-meter construction site to minimize the impact on the mobile phone signals of surrounding residents.
