The power and number of channels of different base stations are different, and the distance between each base station and the prison is different. It is generally recommended that there should be no base stations within two to three hundred meters of the prison area where the mobile phone signal shielding system is installed. If there is a base station, the factors need to be carefully considered. The impact of being too close to the base station and having too strong a signal! signal jammer
Influence from the layout of various buildings in the prison n
The scale, number of buildings, structure, size, floor height, etc. of each prison are different. The direction, power, terrain and other factors of the distribution of mobile phone base stations around each prison are also different. The strength of mobile phone signals transmitted from distant base stations is also different. No, the layout of each prison needs to be designed based on the actual site conditions!
Impact on other aspects
Even in the same environment, base station signals are affected by wind disturbance, air humidity, etc., which will cause fluctuations in signal field strength. In addition, there are also differences in field strength between indoor and outdoor spaces, the ground, building structures, materials, and metal objects that affect mobile phones. Blocking signals has very complex adverse effects.
Selection and technical indicators of shielding equipment n
Reasonably plan the selection of shielding equipment based on project funds. When selecting shielding equipment, attention should be paid to the size of its shielding radius (i.e., power), performance stability, life span, etc. The selection should also be based on the site environment. At the same time, consider using a mobile phone signal jammer with an adjustable radius (that is, adjustable power), or using a directional antenna to control the main emission area (direction) of the shielded signal.
Influence from human factors and normal machine wear n
Cell phone signal shielding systems are installed in prisons. Most of the shielding terminals are installed at relatively high or slightly concealed locations so that they are not detected by ordinary people. However, this does not necessarily prevent man-made damage. The impact of future human factors must be considered, including prison sentences. Prisoners (also resisted by prison guards) artificially damaged or cut off the power supply of the isolator.
