When we are very painful about the noise of the mobile phone around us, we are eager to use a device to effectively shield the surrounding mobile phone signal. At the same time, the device will not affect other electronic devices around us. You can choose to buy a wifi jammer. The wifi network jammer device makes the phone completely quiet.
The production of wifi signal jammer is a complicated process, and it is not possible to piece together them. First of all, you have to understand the working principle of the shield, you have to understand the circuit, you have to draw the picture of the circuit board, and then you need to make the board, patch, solder, debug, etc., one less process can not be done, now on the market The price of mobile phone shields is generally a few hundred dollars, so wifi signal jamming devices are very popular.
At present, wifi signal shielding devices on the market are all in full frequency band, one can shield all mobile phone signals, CDMA, GSM, SCDMA, DCSPCS (1900MHz), PHS, 3G mobile phone signals, WIFi and 4G, 4G1, 4G2 mobile phone signals, etc. All communication signals. The price of the signal jammers handsets is affected by many factors, such as brand, category, specifications, market, etc. The same wifi jammer may have different shielding bands and interference ranges.
After the mobile phone signal shielding device is plugged in, it will send the same frequency as the downlink frequency of the base station, which will interfere with the mobile phone to receive the normal frequency sent by the base station, so that the mobile phone can not receive the signal of the base station, but receives the signal from the shielding device. This signal is not able to communicate and access the Internet, so the phone will not work properly.
Now the mobile phone signal shielding technology is very mature, easy to install and easy to use. Good shielding effect (no dead angle), good heat dissipation, stable performance, simple installation is a free installation. There are many models of mobile phone signal shielding devices like desktop wifi blocker. Pay special attention to the signal segment and shielding range of interference when purchasing, and choose the product that suits you. The cell phone signal blocker can only block the cell phone signal without affecting other electronic devices.
When some mobile phone signal shielding devices on the market are used, there are often some problems. For example, some mobile phone signal shielding devices have poor shielding performance, and often cannot completely shield the mobile phone signal, which greatly reduces the performance of the mobile phone signal shielding device. In addition, the mobile phone signal shielding device has a small range in use and a weak shielding capability, and all the interference devices provided by the jammer-mart ensure quality and free delivery.
