Is it legal to purchase cellphone jammer(0)

The use of signal jammers in schools is typically against the law. Furthermore, it is questionable how the school managed to acquire them initially. Unless the school is located within a correctional facility, the procurement of signal jammers should not have been possible. It is crucial to acknowledge that signal cellphone jammer are subject to strict regulations, and the consequences for their usage are severe if one is caught.

It is likely that your school has implemented restrictions on the wifi network, allowing only school devices to connect. Within our district, we have set up several wifi networks. The Mobile Data Network is dedicated to chromebooks used on campus, while the Staff Network is exclusively accessible to staff members. Additionally, we have the BYOD network for guests, which can be disabled at any time by the school administration. It is worth mentioning that network usage significantly rises during lunch breaks and passing periods.

I believe that in most states it is illegal to operate a radio transmitter without a licence, except for low-power type-approved (in your country) devices within certain frequency bands - e.g. garage door openers, baby monitors, CB radio in some countries, WiFi etc. Cellular radio bills include a yearly licence fee - at least mine used to. It is unlikely that you would get approval to operate a device designed to cause interference; the licence for other devices often includes a clause stating that you will not cause interference. So if you use a GPS jammers you are probably guilty, at least, of an offence of operating a non-approved transmitter without a licence, if not other offences.

The operation of a transmitter inherently exposes your whereabouts to individuals equipped with a receiver, unless you possess a low-power device near a GPS receiver that remains undetectable from more than a few meters away.

Not long ago, a Special Forces soldier was accused of unlawfully killing an Afghan civilian. The soldier in question had witnessed the civilian in possession of a cell phone and, taking into consideration the circumstances and environment, along with other indicators that only experienced soldiers and police officers can identify, determined that the civilian was likely using the cell phone to activate an Improvised Explosive Device (IED). This method of detonating IEDs is frequently employed. Although the soldier was acquitted during the formal hearings and trials, the unit could have prevented a significant amount of time and trouble by utilizing a jammer.

Various styles and strengths exist when it comes to jammers. However, they all possess a key characteristic. These devices are specifically designed to interfere with a particular radio frequency. Essentially, a high-quality jammer can impede electronic communications from one or multiple points, thereby denying cell phone usage, drone activities, and a wide range of other radio frequency devices.

Undoubtedly, the employment of jammers in overseas, military, and contracting operations is significantly less limiting and represents the most effective approach to counter IED attacks initiated through radio frequency. A proficient jammer will effectively hinder remote IED detonation, thus denying adversaries the anonymity they often depend on for their protection. Furthermore, jammers will equally prove highly effective in preventing drone attacks or impeding image and intelligence gathering.
