How to choose the transmitting power of mobile multi-functional cell phone signal jammer for different applications!
While mobile Internet is now widely used, the use of 5G high-power signal jammers is also very common. Signal jammers are mainly used in: college entrance examination examination rooms, conference halls, government agencies, prisons and other places and environments. There are differences in the use of signal shielding devices in different situations.
For example, the commonly used examination room type signal shielding device. Generally, the transmitting power of the whole device is between 20-50W. The shielding device used in the intermediate examination room is placed in one examination room, so that a reasonable shielding effect can be achieved. At the same time, There are low-power shields that will not harm other electronic products and will not cause any harm. For example, a large main conference hall needs to choose signal shielding equipment with a shielding power between 50 watts and 100 watts. If used in prisons, then a high-power signal jammer is needed. The entire device has a transmission power of more than 100W or even hundreds of watts to ensure a higher shielding distance range. Such high-power All the shielding devices need to be operated for a long time, and equipped with industrial power supply to ensure that the shielding device can work continuously for 24 hours. Therefore, when purchasing high-power signal jammer equipment, you must choose shielding products with different power according to the environment of your own use site, in order to ensure faster shielding effect.
1. Applicable to all current mass communication standard mobile phones in China: CDMA, GSM, DCS, PHS, and 3G
(CDMA2000/TD-SCDMA/WCDMA), and must not harm the normal operation of other electronic equipment systems in the prison;
2. Within the prison building (including but not limited to prison cells, corridors, stairways, prompt boxes, etc.), the effective shielding rate should be guaranteed to be above 99.9%;
3. In the production area, the effective shielding rate should be guaranteed to be above 99%;
4. In enclosed small spaces (including but not limited to conversation rooms, storage rooms, bathrooms, etc.) and more secluded venues where the probability of violations is relatively high, the effective shielding rate should be guaranteed to be above 99.9%;
5. In non-shielded areas (including but not limited to administrative buildings, armed police and military buildings, and nearby businesses or residential living venues, etc.), try to ensure smooth communication;
6. Based on the shielding on-site ionizing radiation testing service, the expected shielding effect is achieved;
7. Sufficiently store unnecessary mechanical equipment exports, extend service life and incorporate future development trends;
8. The management system uses centralized power supply as much as possible.
