How to Choose a Cell Phone Signal Jammer?
How to choose a cell phone signal jammers? Buying one is easy, but how to choose the right one for your needs? Listed below are three factors to consider when choosing a signal jammer. They include the frequency bands, the power level, and the appearance. There are many different jammers available for the same purposes, and a wrong choice could result in a returned product, wasted freight, and a lot of frustration.
First, the signal strength of the cell phone must match the jammer’s output power. A simple device that only blocks one group of frequencies will only block signals from three to ten meters. This makes them ineffective for blocking extremely strong signals. You should choose a jammer with a higher power output if you’re planning to block a very strong signal. A jammer with higher power output will be more effective against a wider spectrum of frequencies.
Consider the place you need the jammer. Jamming the signal is necessary in places where you need to keep quiet. For example, you might want to install it in your classroom to prevent distractions from mobile phones. You can hide it in the teacher’s desk or cabinet. This way, you’ll be able to focus on the meeting at hand, rather than answering your cell phone. By blocking the cell phone signal, you can prevent disruptive interruptions, even when you’re not in a noisy area.
In addition to prisons, jails, and other areas with high cell phone traffic, you can use cell phone signal jammers to test the reliability of your equipment and GPS products. These jammers will block commercial signals while not affecting your cell phone signal. However, if you have any doubts, check with your wireless provider or equipment manufacturer. If the problem isn’t a signal jammer, contact the manufacturer of the device and request a refund.
