“We have installed jammers in four examination halls for preventing cheating during exams. Instructions have also been passed to the invigilators to keep strict vigil on movement of students and check suspects thoroughly.” the dean said.
What exactly do they intend to do with the drone cell phone jammer? Unless it's a really shitty drone it'll have rth on loss of discernable signal so unless that thing is relatively high power microwave (enough to overheat and destroy the internal electronics) then it's not going to do all too much aside from maybe forcing soft land if they don't have rth set correctly.
The government told a three-judge bench headed by Justice Dipak Misra that installation of jammers in school buses was "not possible" and they were coming out with steps to deal with the menace of child pornography in its entirety.
Prepare to launch a drone at a joint base with the Iraqi army on the outskirts of Mosul, Iraq. According to the Iraqi general, the in-vehicle signal "jammer" provided by the United States to the Iraqi security forces has greatly reduced the threat of ISIS drones to Seymour.
A mobile signal jammer is an instrument used to protect the cell phones from the receiving signal. The mobile jammer device broadcasts the signal of the same frequency to the GSM modem. The jamming is said to be successful when the mobile phone signals are disabled in a location if the mobile jammer is enabled.

Gai Mar-Chaim, senior partner of the management consulting firm POC, said that the automated drones patrolled by the US Department of Homeland Security (DHS) on the US-Mexico border were attacked by border smugglers (mainly drug trafficking groups).
DHS offers high priority for lightweight anti-cell phone solutions to meet this challenge, and Perfectjammer is the only commercial solution that weighs less than 150 grams and consumes less than 0.75 watts.
A cellular phone is a full-duplex device that utilises two frequencies at the same time. One is for talking while the other is for listening. The signals are handled at the same time.
There are signal jammers that can only block one of the frequencies at a time, which results to the blocking of both because the phone thinks that there is no service in the area because it can only get one of the frequencies.
Though mobile phones have been banned in exam halls, a final year MBBS student of a private college had managed to cheat in a recently held exam through Bluetooth device and a microphone.
