Among the many manufacturers of signal jammers, which one is better? There is a company specializing in the production of signal jammers in Foshan, called signalstorer. Compared with other companies' products, their biggest advantage is that they have a larger choice. At present, their company has two types of signal jammers, built-in antenna and external antenna. At the same time, it also provides program services, which can relieve the school's worries. The reason why the signal blocker in the test room is so powerful is because of its own black technology. It uses the method of blocking the signal to block the mobile phone signals near the test room, so as to achieve the purpose of making the test fair and equitable.
