Optimal use of jamming weapons

Simply pushing lots of CW power into the ether is the most inefficient method of jamming and rarely used because of this. More efficient is a tailored jamming system that is modulated in a way that causes problems in the demodulator of the receiver being jammed, usually by using a high peek pulse power at a critical frequency to the receiver demodulation. Even more efficient is to mess with the stages beyond the receiver such as sending valid modulation that mucks up the computer data processing.

Although the phone signal jammer is so effective. Rabo admitted that there are also concerns about the effectiveness of signal jammers, adding there are no jammers at the Medium Security Compound.Garcia said installing jammers “is a tacit (admission) of the fact that they (officials) cannot even implement that policy (prohibiting the use of cellphones). “There is, I suppose, an existing policy to block all cellphone communications (from inmates). We bought (signal) jammers. In other words, cellphones are illegal. The reason you’re putting in jammers is because even if these are banned, I don’t know how cellphones still find their way inside (the NBP),” Garcia said. Of course, the signal jammer device only prevents prisoners from using their phones, and it doesn’t stop them from smuggling.

Communication jamming devices were first developed and used by military. This interest comes from the fundamental objective of denying the successful transport of information from the sender (tactical commanders) to the receiver (the army personnel), and vice-versa.

The Drive explains why the USAF is determined to use GPS spoofing and cell phone jammer technology but offers no insight into what a GPS blackout might mean for the millions of civilians who live in the Western region of the US.

There is a little control in the schools in the UK, but only to lock your phone to their WiFi. Only school stuff is allowed to be searched up , sites on educational things and student/teacher email etc. Although if you don’t opt for the school WiFi network when it flashes up on your phone first time you try using your internet there, just ignore it and use your cellular data. Although most kids I know don’t have any most of the time. Hope the are trying to find a way of blocking the waves so kids can’t use their phones during lessons at least, just so distracting for everyone around the idiot who can’t live without social media.
