Wireless signal jammer power adjustment is the overall adjustment or frequency band adjustment? from YIFALIU's blog

The vast majority of common wireless signal jammers on the market are not with power adjustment, such as for the examination room signal shielding or for the venue signal shielding, but there will still be a part of the customer base, they are hoping that the shielding equipment has the function of power adjustment. Why is there such a demand? This is the customer does not want to interfere with the signal range is too large, thus affecting or interfering with other unrelated areas, then, with the power to adjust the wireless signal jammer, it is the overall adjustment or frequency band to adjust the transmit power?

Standing in the customer user's point of view to look at this issue, the customer is of course, hope that the wireless signal jammer power adjustment operation, can be simple, convenient and fast to achieve the purpose. For example, through a physical power adjustment knob can realize the output power size adjustment. However, the final result provided by the manufacturer is that such an adjustment function is actually difficult to realize. That is to say, a simple potentiometer knob is basically not feasible for overall power adjustment.

Why did we come to this conclusion? That is because the wireless signal jammer for a variety of frequency bands, standard signals, is divided according to the frequency band, by at least ten or more shielding modules. Each shielding module only for the current frequency band signal interference. We take cell phone signals as an example, different frequency bands, different systems of cell phone signals, even in the same location, it received from the base station signal strength, in fact, there are differences. The result of this difference is that the wireless signal jammer for different frequency bands, different systems of cell phone signals, the effective shielding distance there are differences, and sometimes the difference is also very large. If the use of just an adjustable potentiometer on the wireless signal jammer for the overall power adjustment is obviously not appropriate, the correct approach must be for the different frequency bands for individual adjustment. This is why we can see the situation is: where the wireless signal jammer with power adjustment function, its power adjustment knob number is very much, and the number of these adjustment knobs and shielding module is a one-to-one correspondence.

Finally, but also additional reminder: for a wireless signal jammer power adjustment, relatively speaking, is the effective shielding range can be accurately controlled, but if the user only rely on the power adjustment knob adjustment can only be done to achieve a general regulation, if you want to achieve a more accurate range control, we recommend that the manufacturer of the wireless signal jammer, carrying a professional wireless signal spectrum analyzer. If you want to achieve a more precise range control, we suggest that the manufacturer of the wireless signal jammer should carry a professional wireless signal spectrum analyzer with the help of the spectrum analyzer to display and analyze the power at the same time of adjusting the power level, so as to achieve the final ideal effect.
