Cell App Phone Word Game Scrambled Letters
This compact Cell App Phone Word Game Scrambled Letters device delivers 4W of power and features 8 powerful antennas. The shielding range is up to 20 meters, depending on the signal strength in an area. It effectively blocks all specified signal frequencies including WiFi 3G GSM and Bluetooth. In addition to great jamming and versatility, the device has optional jamming settings. The user can close any tape without affecting other operations on the tape. Also, users do not need to use only all TX frequencies to cover the uplink of the connection. The cell phone jammer will also not interfere with the upstream signal.

Generally speaking, the base station is more prominent on the mobile phone, and the signal strength of the signal is much stronger than that on the mobile phone, so theoretically, it can be sent very far. For example, the radio and television towers used in many large cities are actually equivalent to a large base station. Due to the large output power and high height, one tower can cover all big cities. If the wireless antenna of the base station sends a signal to the sky, because there is no obstruction, the propagation loss will be relatively small, and the range of the signal will be wider. This is just a perspective view of a straight line. Moreover, because there are fewer planes in the sky, the total number of passengers is also very small, and there are few people online, so when the sky is covered, the main consideration is the coverage, not the volume. Because the replacement of mobile phones is fast, especially after the emergence of 5G, the signal transmission of mobile phones is more powerful, and the faster networking effect also increases the difficulty of preventing fraud in the examination room. The shielding effect of the previous Cell App Phone Word Game Scrambled Letters on these mobile phones has been greatly weakened or even ineffective. Therefore, it is necessary to install a 5G jammer that can shield 5G mobile phones at the test site!
