Cell Phone Jammer Law For Buisnesses
There are many Cell Phone Jammer Law For Buisnesses s on the market at present, but most purchasers know little about mobile phone jammers, and they will inevitably encounter some pits. How should we prevent such pits when we buy mobile phone jammers? Chengdu mobile phone jammers will introduce to you The following dry goods knowledge: Is there a communication base station around the college? In the whole process of engineering construction, we often find that customers give feedback to everyone that signal jammers have no practical effect. 2G3G can be shielded, in other words the voice call signal can be shielded, but the 4G signal cannot be shielded. In fact, the output power of each mobile phone jammer is different, generally 4G1 and 4G2, the output power is around 2W, in other words 33db. If there is a communication base station within 100 meters, cell phone jammer Such equipment will not shield 4G signals. It will also happen, and customer feedback will have practical effects.
The mobile phone (234G) for voice calls replaces shielding. Suppose you shield only 23G or only 45G, which can be adjusted before leaving the factory.

That is, if you only want to block voice calls or WIFI, the manufacturer can push 2G3G on the server, and the cost will also come out. Distinguish the output power size. This is the most fraudulent area, and it is also an area where manufacturers often play with cats. Since it is really necessary to measure the specific output power size, it is necessary to use a technical professional spectrum analyzer. The average customer is unlikely to have such machinery and equipment. Therefore, the degree of this process depends on the technical expertise of the customer in selecting machinery and equipment. Output power size: Cell Phone Jammer Law For Buisnesses Generally, it can be divided into small output power, medium output power, , and the output power is between 3W-100W.
