If used properly, signal jammers can be a beneficial tool. Jammers can be used for a variety of purposes, including preventing illegal communications or helping to reduce distractions.
Normally, cell phones are not needed for work.
Like any other tool, cell phones can be used for both productive and non-productive purposes. If cell phones start to cause trouble at work, employers have the right to install signal jammers to stop the phones from interfering with work.
If employees can't stop using social media or texting, then this can be a great option to simply fire the offending employee. What they can't access, they can't use.
If phone calls come in at the wrong time during a lecture, speech, or religious ceremony, it can be a big distraction. With cell phone signal jammers, these calls may not get through at all.
Unfortunately, asking individuals to turn off their devices doesn't work in large groups. A significant number of people will always leave their devices on, for whatever reason.
Whether or not this is indicative of a larger societal problem, the fact remains. Even during a funeral, the occasional phone call can interrupt a moment of silence or prayer.
In either case, a signal jammer blocks the frequencies that a phone needs to receive a call, thus preventing the phone from ringing because the call won't be received in the first place.
Signal jammers are often used by law enforcement to create signal dead zones where things like phone calls can become a problem, which is partly related to the above argument.
The most straightforward application in the past has been blocking signals that can be used to remotely detonate bombs. These bombs require wireless signals, which are often provided by cell phones and can be blocked like other transmissions.
The ability of a jammers to block criminals from communicating with the outside world is less obvious. This could be useful in a variety of situations, including raids or hostage situations. It makes it harder for thieves to plan together.
To be clear, these are tactics that the military and law enforcement can deploy, but they represent one of the most important applications of this technology. If implemented correctly, it can save lives.
Some parents have begun using signal jammers to get their children to be quiet for a certain amount of time. If the jammer is turned on, Wi-Fi, mobile service, or both are disabled.
This is an effective way to ensure that children follow the rules when doing homework or sleeping, but parents must be careful about the power of the jammer (or they may receive complaints from neighbors).
If the situation seems serious, remember that the cell phone blocker can be turned on or off at any time. You can turn it off when the children do not need to concentrate on other things.
