The main function of the electronic jammer is to block the connection between the mobile phone and the base station, so it plays a very important role in its use. Nowadays, electronic jammers have been widely used in various places, especially in school examinations, which are equipped with the most advanced means to avoid cheating. Then, will the use of mobile phones in electronic jammers be completely shielded? Because the manufacturers of electronic jammers are different, the ability of jamming signals will be different. In addition, the chips used are also different, which will affect the scope of the electronic jammer.

The electronic jammers produced by our company are generally isolated by eight built-in antennas. Although the antenna of the electronic jammer is not exposed, its effect is no different from that of the electronic jammer with an external antenna, which can effectively shield its area. If you are worried about the coverage of the shielding area, you can measure the specific frequency band of the signal in the environment if possible, and then we can adjust the corresponding frequency band signal of the electronic jammer to meet the customer's needs. Or choose an electronic jammer with higher relative power. This can also meet the needs of users.

Finally, customers who need electronic jammers should contact reliable manufacturers to buy them. The low-quality shields can not achieve the effect of on-site use and can not guarantee the later maintenance of electronic jammers.
