With the popularity of mobile phones, the demand for full-band jammers in confidential meetings, standardized tests, prisons, detention centers and other occasions is also increasing, and the market size of full-band jammers has also expanded significantly. However, many users lack sufficient understanding of full-band jammers. In order to achieve better results, they often choose jammers<\/a> with higher power, but this also has certain risks.<\/p>\n\n\n\n

The principle of full-band jammers is to transmit interference signals over a large range, so that the downlink signal of the mobile phone is interfered, causing the mobile phone to fail to work properly. As a signal transmitter, the mobile phone itself will naturally generate radiation. At present, the transmission power of full-band jammers is between 1W-500W, while the maximum transmission power of GSM mobile phones is generally 2W, and the GSM macro base station is between 20W-40W.<\/p>\n\n\n\n

Generally speaking, for standardized tests and small meetings, choosing a full-band jammer with a transmission power of 2W-10W can achieve the expected effect. However, according to surveys of major educational institutions and important meeting places, many places tend to give priority to high-power jammers. For example, a classroom with more than 20 students is equipped with a full-band cell phone jammer<\/a> with a transmission power of 50W in each classroom. Upon inspection, it was found that due to lack of attention and unified management, jammers were sometimes not turned off in time, resulting in continuous transmission for weeks. Long-term high-power transmission in a specific area may cause adverse effects. Therefore, I strongly urge all institutions using full-band jammers to consider the following points:<\/p>\n\n\n\n

    \n
  1. Avoid blindly choosing high-power jammers<\/a>. For classroom environments, low-power full-band jammers are sufficient to achieve the required shielding effect.<\/li>\n\n\n\n
  2. Jammers should be turned off in time after use to prevent continuous radiation.<\/li>\n\n\n\n
  3. Choose full-band jammers with good reputation, guaranteed quality, strong technology, products with multiple power requirements, relevant test reports, and radiation levels within a safe range.<\/li>\n\n\n\n
  4. Passive and active jammers: Full-band jammers can be divided into passive and active types. Passive jammers passively receive and forward radio signals, while active jammers generate their own radio signals to interfere with other devices. Active jammers are generally more effective, but also easier to detect and track.<\/li>\n\n\n\n
  5. Purpose: Full-band jammers have a variety of uses, such as preventing eavesdropping, disrupting illegal communications, and protecting electronic devices from information leakage. However, the potential for misuse and harm has led governments around the world to increase regulation and control of full-band jammers.<\/li>\n\n\n\n
  6. Use as an attack tool: Full-band jammers can also be used as an attack tool. For example, in a cyberattack, an attacker can use a full-band jammer to disrupt a victim’s WiFi signal, preventing them from accessing the internet.<\/li>\n<\/ol>\n\n\n\n
