Codes To Remove Blocks On Cell Phone Metro

During the college entrance examination, in addition to the congestion and quietness around the school, the mobile phone signal may not be good. At this time, you must not resent the operator. As a college entrance examination candidate, you find a device similar to a router when you walk into the examination room. Don't be "excited" To be considered "on the Internet", that might be " Codes To Remove Blocks On Cell Phone Metro ". The "mobile phone signal jammer" can work perfectly. At that time, the frequency band used by most operators was relatively fixed, the bandwidth was also narrow, and interference was relatively easy. With the rapid development of communication technology, the development of 3G and 4G communication technology has made the "signal jammer" encounter a dilemma. The signal interference originally designed only for 2G, because of the frequency, cannot cover the 3G and 4G signals, which will cause the shielding to be ineffective. Fortunately, cell phone jammer is also developing, and soon there will be an interference function specifically for 3G and 4G frequency bands, which can block these three frequency bands at the same time and space. The principle of cell phone signal jammer The cell phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process, the transmit power is in the order of watts, and the shielding range is adjustable, generally tens of meters.

Technology is advancing by leaps and bounds. Codes To Remove Blocks On Cell Phone Metro Catching up with the development of communication technology to the 2G era, cell phone signal jammers can work perfectly. At that time, most operators used the same frequency band, and the frequency was relatively fixed, so it was relatively easy to interfere with it. After the addition of 3G and 4G, the diversification of signal frequency bands follows the rapid progress of communication technology. 3G and 4G communications were quickly applied to practical scenarios. At this time, the mobile phone signal jammer encountered a dilemma, that is, the signal interference originally designed only for 2G, because of the frequency, it could not cover the 3G and 4G signals. This also renders the mask ineffective. In this case, the development of communication technology began to force the simultaneous development of shielding technology. In order to be able to interfere with 3G and 4G signals, cell phone signal jammers quickly evolved the interference function specifically for 3G and 4G frequency bands. So there is a problem that 2G, 3G and 4G all need to be shielded, so how? What about blocking all three frequency bands at the same time and space? The eight-antenna mobile phone jammer can shield 2G/3G/4G at the same time. The answer is very simple. It is to repeatedly play the interference bands corresponding to the three signals in a loop to cover the three bands at one time, and the interval of this cycle is very small, so that the mobile phone There was no chance to speak at all, so I could only sit down obediently.
