Wifi jammer is a relatively professional modern communication signal shielding technology, especially in the special environment of prisons, which puts forward higher requirements for mobile phone signal shielding technology. For example, in the application environment of the communication signal shielding system of a general conference, the participants come and go in a hurry, and there is almost no time to "search" for the blind spot of communication signal shielding. In the special environment of the prison, the number of people is dense and the activities are more concentrated. This is the time to use a wifi signal jammer to block it.
How to evaluate the effect of the prison wifi jammer system?
In order to achieve no shielding blind spots in the prison, the test should be repeated, and professional equipment detectors should be used in places with strong signals such as "windows" or "every corner". radiation, and shielding of other systems; achieve no blind spots; meet the testing regulations of relevant departments
The problem of shielding effect and external shielding?
A high-quality wifi jammer device must be completely shielded without affecting the communication of residents, not letting the people complain, so that the shielded area is more accurate, and there is no shielding outside the shielding area. Only then can it be regarded as a complete acceptance project.
The problem of upgrading and expansion?
Wireless communication technology is developing rapidly. Currently, 5G is in the trial operation stage. Yesterday, the system could be completely shielded. Today, there may be problems. Therefore, the construction of the shielding system should be modularized, and it can be easily upgraded according to the changes in the surrounding communication facilities, so as to substantially save the project investment and achieve permanent shielding.
Factor 1: Shielding effectiveness of wifi signal jammers The so-called effectiveness of mobile phone signal jammers refers to whether there are blind spots or leaks in the shielding effect. In the vicinity of some prisons, there may be transmitting signal sources with strong mobile phone signals. In order to achieve a good shielding effect, it will take a lot of materials and energy accordingly, and the cost will increase accordingly. Therefore, the better the shielding effect, the higher the cost will be. In practical applications, the shielding requirements of the prison area are generally higher, and there are slight leaks and blind spots. Some personnel may seize this loophole so that mobile phones can be used in the originally stipulated shielding areas, which cannot achieve the original intention of shielding mobile phones.
Factor 2: The trouble-free time of the wifi blocker If the original stipulated trouble-free service life is 1 year, and the actual use without trouble reaches 3 years, the cost performance will be tripled. If the original fault-free service life is 1 year, and the actual use is less than half a year, there are often failures. Although it is a free warranty, the risk caused is immeasurable, and the personnel resources are also wasted. The corresponding cost performance is greatly reduced.
Factor 3: Wifi frequency jammer shielding externally If you do not consider external shielding, it will be relatively easy to simply shield the mobile phone signal, as long as you increase the shielding power. However, it is necessary to ensure that the shielded area has no blind spots and no leakage points. The power intensity in the shielded area is relatively large. If there is a little leakage, the external shielding will be very large. This requires that the shielding design should be fully considered and controlled technically to achieve accurate and efficient shielding without external coverage.
Factor 4: The cost of a Bluetooth wifi jammer should follow the shielding requirements and budget. You can’t blindly choose a cheap machine, and you can’t think that the expensive one is good. In actual choice, word of mouth is very important, and it is necessary to inspect past cases and try the shield yourself. the effect, and then do the selection.
