Cell Phone Scrambler Legal In Us
As a mobile communication device, a mobile phone needs to establish a connection with a nearby base station when communicating, and then access the core network to find the communication destination. Indeed, radio communication tools with dedicated frequency bands "came into being" in this context. The working frequency band of these devices is selected outside the frequency band covered by the mobile phone jammer, Cell Phone Scrambler Legal In Us has no effect on them. For this special radio communication tool, the examination room is specially equipped with a monitoring vehicle equipped with a radio monitor for real-time monitoring of radio wave signals from unknown sources. So how exactly does the radio detector work? Because electromagnetic waves have the characteristics of "near big and far small", by constantly moving the detection vehicle, the monitoring equipment can locate the signal transmitter according to the distance and the strength of the signal, and capture the offenders who use these radio communication tools on the spot. Nowadays, drones have also appeared in the examination room, which can perform signal positioning faster. Therefore, neither mobile phones nor these special radio equipment can play a role in the examination room. cell phone jammer
