Gsm Cell Phone Jammer Using Arduino Technically speaking, it is actually just a small branch in the wireless information shielding system. Its essence is electronic countermeasures, or co-channel interference, which uses equipment to send out high-frequency signals through antennas to make mobile phones generate errors when receiving downlink signals. The code cannot be identified and connected to the network, and the mobile phone shows no network status, which achieves the effect of signal shielding; for signal shielding, everyone knows that the downlink signal of the base station needs to be interfered, but due to a series of factors such as technology, cost, price, and production, some It is difficult for manufacturers to only interfere with the downlink, so some illegal manufacturers do not make precise frequency range adjustments in order to improve the effect of prison signal interference. cell phone jammer This causes some interference energy to the uplink, which can indeed greatly improve the interference capability and play a corrective effect, but at the expense of the public interest;

The shielding range of the mobile phone jammer is based on the size of the Gsm Cell Phone Jammer Using Arduino power. If the shielding range is different according to the strength of the local environmental signal during the field test, for example, the weak shielding range of the indoor signal is large, and the outdoor use accessory has a GSM base station. GSM signal is close to the outdoor shielding range! As everyone knows, 2G, 3G, 4G and 5G: Before buying, you need to know which signals you want to block. Ordinary mobile phone signals (2345G) can be selectively blocked. If you only block 23G or only 34G, this It can be adjusted before leaving the factory, and there are also 2.4GWIFI, 5.8GWIFI and other frequency bands. Generally, ordinary signals can be quickly shielded. Shielded frequency bands: CDMA800, GSM900, SCDMA1800, DCS1800, PHS1900, TD-SCDMA (Mobile 3G), CDMA2000 (Telecom 3G), WCDMA (Unicom 3G).
