Fabric That Blocks Cell Phone Radiation And Distance Related

The influence of cell phone jammers is a certain clear space. The shield radius is determined by the path attenuation and the signal level of the receiving tower. In order to realize the influence of mobile phone signal influencers on the mobile network, it is necessary to ensure that the field strength of the signal sent by the influencer is higher than that of the mobile signal in the affected area. The closer the influence position is to the signal tower, the stronger the field strength and the smaller the effective influence area. Conversely, the farther the impact point is from the signal tower, the weaker the field strength and the larger the effective impact area. It can be seen that within a certain transmit power, the influence range depends on the field strength in the affected area, no matter how large the Fabric That Blocks Cell Phone Radiation power is, as long as the transmit power is a fixed value, with the increase of the distance, the influence signal strength will gradually attenuate, thus losing ability to influence. The table below is a comparison table of distance and path attenuation.

Then the output channel power of cell phone jammer , the signal level of the signal tower, and the gain of the coverage line can determine the theoretical coverage radius with the reference value. Generally speaking, a signal jamming mobile phone is an electronic device that can temporarily interrupt the same-frequency mobile phone signal within any interference range transmitted by a base station. Therefore, it can effectively prevent the mobile phone from interfering with normal use within the effective range. Historically, military and law enforcement officers have often used Fabric That Blocks Cell Phone Radiation or cell phone jamming to shut down or control your cell phone communications in emergency or threatening situations. With the passage of time, mobile phones are almost everywhere in China, more and more people are tired of other people's private conversations, so that more and more people can buy your products with confidence, we are professional mobile phone interference manufacturers first-class technology and equipment.
