Modern battlefields are complicated, and have been further muddled by the addition of cheap jamming technology. It’s now possible to buy a simple GPS jammer yourself, and there have been plenty of instances of nefarious actors using the tech all over. And, it makes sense. Future wars will be fought chiefly with information. They’d have to be. Technology being what it is, if you can kick the essential services out from under your opponent, you can cripple their ability to respond or conduct themselves. It’s a scary world, indeed.
Networks can be jammed by flooding the AP with Deauthentication Frames in what is know as a deauth-attack. By assuming the identity (MAC address) of a station on the network, the AP will deauthenticate the real station. The real station will then attempt to reauthenticate, but, it will never succeed due to our barrage of deauth-frames and its network access will be effectively blocked.
The military has gotten lax over the years. electronic devices has been blocked from some buildings since 1985. There are sections that will not allow phones in the buildings now. With the popularity with phones and how chreap they are everybody has one now. They should start collecting them at the door or running jammers.
Since jamming on the hardware level is out of the question, a number of developers have found a way to clog up WiFi communications in software. This is much more akin to a denial of service attack, where tools are used to repeatedly spam deauthentication packets at WiFi access points and clients to force them to disconnect. With the appropriate software and a powerful WiFi adapter that supports packet injection, an attacker can put a stranglehold on legitimate communications.
Although the cell phone 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 jammer device only prevents prisoners from using their phones, and it doesn’t stop them from smuggling.
