The mobile phone jammer must be installed in a well-ventilated place?

Android wireless communication must be secure enough to effectively receive the carrier-to-interference ratio in order to complete the communication. A mobile cell phone jammer is a mobile phone that generates the same frequency to interrupt the communication connection between the phone and the base station and destroy the receiving state of the phone, thereby receiving interference signals. Realize the exchange of shielding effect. The interference shielding power is constant and is completed by determining the unobstructed space shielding radius attenuation path received at the signal level of the base station. The antenna must first be connected and powered. When the host is forbidden to work, remove the antenna. The shielding equipment should be placed in a well-ventilated place, and large objects should be avoided to ensure cover.
