The era of signal jammers has arrived

A British school principal who wanted to stop her students from logging onto the Internet by using phone jamming technology has been told by authorities that any such action would be illegal, according to media reports.

The gun can launch directional high-power radio frequency interference, interference of unmanned aerial vehicle (uav) control system, to cut off the unmanned aerial vehicle (uav) with rear data links or radio communication between control center, the uav autonomous flight, lead to crash, landing, or turn back

The Chinese military has been equipped with the U.S. military to deploy drones to interfere with radiation weapons. Large electronic warfare equipment can even interfere with and capture the enemy’s large drones. For example, Russia’s “car field” electronic warfare countermeasures system has some powerful functions that are not known to the outside world. The radar system, which can suppress 50 aircraft at a height of 30, 000 meters, can also launch electronic attacks on fighters and drones within 100 square kilometers. In October 2011, Iran captured an American rq-170 “sentinel” stealth drone using the russian-supplied electronic countermeasures system.

Drones do not get enough accurate data on their own coordinates. Therefore, the flight control of the uav is combined with GPS satellite navigation system and inertial navigation system. The drone also needs to know its precise location when taking a photo, so it has a GPS signal receiver installed on it.

As it is, the unmanned aerial vehicle (uav) of GPS receiver vulnerable to electronic jammer gps, lead to uavs can only rely on the inertial navigation system based on gyroscope, cannot get enough accurate coordinate data. Even if there is no precise terrain measurement, with the aid of cameras and video cameras for intelligence will not have any value, at this time of uavs at most is a flying camera, whether from a military perspective, or from the Angle of surveying and mapping of civilian, would mean a loss.

Julia Polley was so frustrated with students accessing Facebook and other social media during classes that she told parents she would block phone signals at Wensleydale School and Sixth Form College in Leyburn, North Yorkshire.

A middle school teacher said, I would allow them, but with some technology implemented to limit their accessibility. The easiest solution would be to install commercial-use cell-signal jammer into the classrooms. These could be small in area of effect, so after exiting the classroom, normal functionality would return.

Recently a Spokane, Washington school principal bought a wifi jammer to block cell phones from working while students are in class. The jamming device was turned on during class time and turned off during passing periods and lunch hour. His reasoning for the measure was frustration by the continued distraction of cell phone texting and calling during class.

This principal wasnt even jamming the phones all day, just during class. Not only that, schools have rules against using cell phones in school, especially during class. My concern would be that cheating could go to a whole new level as kids could pass the answers to each other through texting. Not only that, teasing and gossip could become the priority rather than learning.
