Jamming a wireless radio requires knowledge of its broadcast frequency as well as the right equipment to jam that frequency. Among them, radio frequency jamming, or "jammers", can be used to disrupt the RF signal of the drone, causing it to fail. In recent test scenarios however, analysts agree that signal jamming as a counter-measure often does more harm than good. Spoofing, on the other hand, is more challenging. This type of jammer's block range up to 1500 meters, and even high-altitude UAV can be shot down. •A jammer selectively targeting the PDCCH would have to decode a couple of system parameters sent in the SIBs •To target every UE a jammer would have to jam every subcarrier, but only with a duty cycle around 10% •Such a low-duty-cycle attack could also act as a form of automatic gain control jamming 14 Hacking is sending false messages which the system sees as genuine messages and thus the system acts on these messages. It did, even turning on the siren once motion was detected even if the base station was offline. A simple looking RF signal jammer circuit can be seen in the above diagram, which may be capable of jamming all sorts RF signal within the range of 5 to 10 meters. GPS signals can be jammed or spoofed relatively easily and for low cost, and methods are evolving. So, the only true option to defeating the intruders with a jammer is with hybrid security cameras.
