There are two fairly old and well-known methods to overcome this GPS jammer. First, one of the most effective alarm jammers is a device that can deceive the base station. Recently, the US authorities used it for tracking. In short, these devices claiming to be cell phone towers make any GSM device think they are connected to the cell phone tower and all traffic is going through the gadget.
Using this gadget will put GSM vehicle alarms at risk. Another point to consider when dealing with such alarms is that you cannot use GSM jammer. If someone near you is using a cell phone signal jammer, this warning will be invalid. No one can lock or unlock it. However, please check the latest research by Don Bailey and Matthew Solnic, which can be considered a good security measure.
The main disadvantage of battery-powered wireless microphones is the limited manual time, but they are much easier to install. The working range of these errors is different, the sound can be heard, the range is 15 to 80 feet. The transmission radius may be very large, ranging from ten meters to several hundred meters. Sometimes, the devil can use the relay network to continue sending signals.
Wireless microphones can use different frequency ranges, the widest ranges are 140-200 and 450-480 MHz. The higher the frequency, the greater the transmission range and power consumption. Likewise, higher frequencies are more likely to penetrate walls and other obstacles. Fortunately, special receivers can be used to detect these interference signals. However, the advanced version may have special signal modulation, so you cannot monitor it. In this case, you can try to use a UHF/VHF jammer to prevent its spread.
