The signal covering range of omnidirectional antenna

 The omnidirectional antenna of mobile phone jammer is common in normal use.
In such an environment, the domestic cell phone industry can withstand the pressure of the tenacious, continue along this road, the key is the strategic choice, and to the right to develop an effective strategy, we must develop the inside and outside the enterprise system environment comprehensive analysis.

So that these modern communication equipment and data transmission between the Internet more quickly and efficiently, as wireless communications to widen the road. Bluetooth uses a distributed network architecture and the fast frequency hopping and short packet technology to support point to point and multipoint communication, working in the global generic 2.4GHz ISM (ie industrial, scientific, medical) band.
