GPS monitoring is real and some of us don’t like it.Learn more about GPS jammer, how they work and what Geotab does to detect threats.
Keep reading to learn everything you need to know about how a GPS jamming device works.
In recent years, with the continuous development and popularization of communication tools such as mobile phones, and the continuous improvement of the technical level of mobile communication tools, especially the promotion and application of 3G, 4G and 5G technology this year, prisons, detention centers, drug rehabilitation centers, etc. The negative impact of venues is becoming more and more prominent. In prisons, detention centers, and other classified settings, all mobile communication devices are expressly prohibited, not only to prisoners but also to supervisors. If mobile phones are brought into prisons by criminals and put into use, it will bring great harm to the management and security of prisons, detention centers and other places. Some prisoners make phone calls, send text messages, obtain information, threaten witnesses with illegally smuggled mobile phones, and even form gangs to break out. To this end, the installation of best cell phone signal jammer systems in prisons and other prison premises is imminent. At present, the power and channel of each base station are different, and the distance between each base station and the prison is also different. It is generally recommended that a base station is not required within 200 meters or 300 meters of the monitoring area where the mobile phone signal jammer system is installed. If there is a base station, it is necessary to consider the impact of a high probability of shielding strong signals on the base station.
1. Influence from various building layouts in prisons.
The size of each prison, number of buildings, structure, dimensions, height of floors, etc. All are different. The distribution direction, power, terrain and other factors of mobile phone base stations around each prison are different, and the strength of mobile phone signals transmitted from remote base stations is also different. How to distribute the sites of each prison needs to be designed according to the actual situation.
2. Other influences
Even in the same environment, the base station signal will be affected by wind interference, air humidity, etc. This will also cause fluctuations in the signal field strength. In addition, there are also differences in the field strength between indoor and outdoor. Ground building structures, and metal objects have very complex adverse effects on cell phone jammer
3. Selection and technical indicators of prison jammer equipment
The selection of jammer equipment should be reasonably planned according to the project funds. The selection of jammer equipment should pay attention to the size of its shielding radius (that is, the power), performance stability, length of life, etc., and also decide whether to select the type according to the site environment. At the same time, consider using a wireless signal jammer with adjustable radius (that is, adjustable power), or using a directional antenna to control the main emission area (direction) of the shielded signal.
