Cell Phone Jammer: Everything You Should Know
Cell phone jammer is a device that blocks or interferes with the regular operation of mobile phone signals. It blocks all incoming calls, messages, and the internet. It is done by sending out radio signals at some particular frequencies used by mobile phone. Our smartphones will become useless at that time.
It is primarily used in specific areas where we don't want to allow people to use a mobile phone. It is mostly used in public places like movie theatres, hospitals, and government buildings or during military operations. It can also prevent students from using a mobile during class or exams.
How Does a Cell Phone Blocker Work?
The cell phone signal jammer disrupts communication by holding up radio waves in an area. It is similar to a radio silence zone. It prevents any incoming or outgoing calls or texts. The cell phone signal jammer emits the same frequency to disrupt an incoming channel.
When you turn on your signal jammer, it will create an area and begin to scan from the low-frequency band to the high one of the wireless network; at the same time, it will send a white noise spam signal within its working area. In that way, the "real" signal between your cell phone and the base station will be interference; your phone cannot detect the signal sent from the base station, so it can't be called. Since the signal also can't be sent out to the base station, you can't dial out within the jamming area. The telecommunications are totally BLOCKED. The size of the jamming area depends on the jammers' range; the most common range is about 20 meters.Â

Is There Any Way to Detect a Jammer?

How to Choice a Cell Phone Jammer?
Choosing the cell phone jammer that can meet your need is not an easy job, especially considering so many options lie there. Here are some suggestions from Jammer Master to help you make the decisions.
We think there are two questions you should ask yourself when purchasing a cell phone jammers.
1. Where are you going to use it?
If you want to block the signal in small spaces indoors, then go for low-power cell phone jammers. They are enough to get the job done, and the prices are lower. On the other hand, if your jammers will be used in large and open outdoor spaces, then it's better to go for the high-power jammers. Since the phone signal strength in outdoor spaces is higher than indoors, using a high-power jammer can not only jam for a more extended range but also reach a better jamming result.
2. Do you need to block the 5G?
Our jammers can block all channels but not every mold support 5G jamming. If 5G is one of your targets, you should check out the details on the product page.
3. Do you need to hide your cell phone jammer?
We have a phone jammer that looks like a power bank, or you can say it's a power bank with build-in signal blocking features. If you want to hide your jammer, you can't get wrong with it.
