Whatever radio interference, radio repeating and interference by increasing its transmission power to improve the availability of radio signals in shortwave radio propagation of highly reliable predictor of hard, so the interference occasionally found one day it's not particularly effective. The receiver can't understand which signal it's receiving. We've been able to block cell phone signals, GPS interference. It is effective to prevent the transmission of signals from the network.
The ON/OFF switch with a button is easy, and the green light indicates that the device is working, so you don't need to operate the antenna to install, configure, or set the software. The wifi jammercan identify a single transmitter to assess its effectiveness.
