How to crack the signal jammer?

Admin Posted on 2022-10-20

The wifi jammer uses the latest Israeli interference technology to generate stable electromagnetic signals, covering the frequency bands of mobile communication GSM, CDMA, GPRS, local calls, and PHS, so mobile phones cannot be used in some specific places, thus solving some current problems. Negative effects of cell phone signal in life. The common wifi signal jammers on the market have the following frequencies: 869~894MHz; 925~960MHz; 1805~1880MHz and 1900~1990MHz, etc. The working frequency bands are CDMA800, GSM900, DCS1800, and PCS1900. It can control a range of about 40 meters in diameter, using DC-DC converter input voltage, and 5V output voltage. After the listing of 3G signals, the working frequency bands of wifi jammers on the market have also been upgraded from the previous four frequency bands to five frequency bands. On the basis of the previous four-band, there is an additional frequency band of 2100 to 2200. Used to shield and interfere with the 3G band. It uses frequency multiplication, frequency division, frequency hopping filtering, and other technologies to analyze the required shielding frequency for the uplink and downlink channels of the mobile phone system; customizes a spherical shielding space according to the power of the shield, and automatically forms a shielding magnetic field within the specified range. Make mobile phones (including PHS-China Telecom PHS GSM-China Unicom, China Mobile, and CDMA-China Unicom) ineffective in this space. When the wifi blocker is in a working state, it can disable the function of sending and receiving signals of mobile phones within the specified range, and cannot dial out or dial in, so as to achieve the purpose of mandatory disabling.

The method of cracking three wifi signal jammers

Crack the wifi jammer device method one

Enter your mobile phone settings, click "Network Settings", change the network mode to "Manual Mode", then enter "Network Search", wait until the words "China Mobile" or "China Unicom" appear, then exit immediately. The mobile phone will have a signal, but the length of the anti-blocking time depends on the quality of the mobile phone. This method works for most mobile phones. Principle: The work of the mobile phone is originally within a certain frequency range. The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method. Then the jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station so the mobile phone cannot establish a connection with the base station. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc.

Crack the wifi signal blocker method 2

Because the working principle of the blocker is to block the mobile phone by interfering with the mobile phone signal in the specified band, as long as the receiving and transmitting frequency of the mobile phone is modified, it can be prevented from being blocked. The transmitting frequency is 850-1900MHZ, which is much larger than the shielding range of the jammer, so as long as the receiving and transmitting frequency of the mobile phone is adjusted to the maximum in the mobile phone settings, the mobile phone signal can be received normally.

Crack the wifi frequency jammer method three

This method has relatively high requirements on the mobile phone and the environment, but the effect is also the best and the most concealed. The premise is that the mobile phone must have wifi wireless Internet access function and there must be an available wireless network around. After using the mobile phone to search for and successfully connect to an available wireless network, even if the mobile phone has no signal, you can still surf the Internet and not use traffic.
