The practicality and practical significance of WiFi interference

WIFI jammers effectively disable wireless signals, bluetooth, WIFI. A wireless network works by communicating with its service network via a base station. A WIFI jammer typically prevents the wireless signals from receiving signals from base stations. As a result, the WIFI does not attempt to transmit to a base station, even though it may be within range.

While some drone guns shoot actual ballistics in hopes of damaging any unwelcome aerial visitors, most modern anti-drone guns use wifi jammer frequencies to confuse the incoming UAV. When a drone’s radio signals are interrupted or continuously jammed, the UAV either lands as a precautionary measure or returns back to its origin. Either way, the goal has been accomplished—your drone gun got rid of the intruder.

Whilst evading such cell phone jammer is easily possible and having an autopilot likewise, are they currently built into the available drones in a way that can not be overridden by a jamming system who's manufacture has shall we say a not publicly known arrangement with the drone manufacturer?

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.

Can WiFi jammers stop drones?

Stopping drones is difficult. “Technological solutions to detect and disrupt drones are in their infancy,” Rosenstein said, adding that the Justice Department supports regulatory changes that would make it easier to deploy interdiction technology and cellphone jamming.

Phones are attracted to a fake network. It is selective - staff or nearby residents' phones can be put on an unaffected "white list". Success can be quantified - phones, and their owners, can be identified. Illicit phones can be monitored rather than blocked. It is more expensive than blanket signal jammer

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.
