Phone Jammer: What Is It?
Phone jammers are portable gadgets that give the finest solutions in places where cellular service is typically prohibited. They interfere with mobile phone and base station signal transmission. Mobile phone jammers use the same frequencies as cell phones to impair cellular networks. These radio waves produce interference, making it difficult to use calls or mobile Internet in the room where the phone jammer is functioning.
When the mobile phone signal jammer is activated, all active cell phones in the area will display "NO SERVICE." Other electronics do not interfere with non-cellular communications; therefore, you are not at risk.
Phone Jammer: How to Choose?
Here are three tips to help you pick the best phone jammer:
- Make sure you're familiar with your network's frequency. The most widely used frequencies in the world are 900 MHz and 1800 MHz.
- Learn about the specifics of your operator. For example, how often you need to work - 3G, 4G, CDMA or GSM. You should research this before buying a telephone muffler that can cover the frequency you need and work with bands in your area.
- Determine the required power and purpose of your actions. Tiny and portable devices are enough for a limited location, such as a classroom. However, if you want to use it in a 10,000-seat theater, you will need a powerful mobile phone muffler with a wide range of suppression.
