Nowadays, there are various cell phone signal jammers on the market, but it often happens that the mobile phone signal cannot be blocked. So this involves the problem of the frequency band of a mobile phone signal jammer. So, what frequency bands can a mobile phone signal jammer block?
Currently, the common mobile phone signal jammers on the market have effective frequencies: 869~894MHz; 925~960MHz; 1805~1880MHz and; 1900~1990MHz, etc. The functional frequency bands are CDMA800, GSM900, DCS1800, and PCS1900. The above are all 2G/3G function frequencies of the three operators China Mobile, China Unicom and China Telecom. Nowadays, the evolution of 4G Internet and even 5G style is no longer difficult. The jammers currently on the market can no longer meet the rapid development trend of communication style.
The SEI0635 high-performance cell phone signal jammer (all-in-one) is a new technology product that our company adopts advanced technology and carefully develops according to the continuous development trend of communication style and based on the actual situation of China Mobile's communication technology. It can operate at 1-25 meters longitude ( About 10-250 square meters, the jammer range can be adjusted according to the required site) interior decoration partition GSM/CDMA/DCS/3G (WCDMA, TD-SCDMA and CDMA2000); and 4G mobile phone signals, 2.4G and 5.8G network signals, It makes it impossible for the mobile phone to make and connect, and cannot send or receive short messages, but it will not affect the work of other electronic products, thereby ensuring the safety of the required site. The mobile phone is outside the decoration partition range, and It can be recovered and used without any harm to the body.
This equipment can block all 2G, 3G, and 4G formats of the three major operators of China Mobile, China Unicom, and China Telecom, including CDMA/GSM/DCS/TD-SCDMA/WCDMA/TD-LTE/LTE - Multiple frequency bands such as FDD/WIFI, while supporting smooth upgrades to meet future 5G and long-term evolution requirements.
It is worth mentioning that the actual signal blocker spacing of the mobile phone signal jammer is directly related to the surrounding wireless environment where the device is located. When the nearby base station signal of the corresponding frequency band is stronger, the closer the device's jammer spacing is Small; under the coverage of base station signals of the same strength, the greater the signal strength of the equipment and the smaller the obstruction, the longer the distance between the shields of the equipment.
