If it is in a normal use environment, it is not complicated to install and debug the mobile phone signal blocker. Generally, you only need to turn on the host switch after powering on the device, and use the mobile phone to observe the working status of the mobile phone at different positions from the shielding device, which can be very intuitive. The judgment read out the shielding effect. However, once you encounter a complex use environment, you need to use a spectrum analyzer to help when you need to analyze the signal on site or formulate an adjustment plan. At the same time, it can also fully reflect: the installation height of the spectrum analyzer for the cell phone signal jammer importance!

The complex usage environments we are talking about here can be roughly divided into two categories:

1. In the on-site environment, the base station signals transmitted from the mobile phone base station have various formats, and the signal strength varies greatly, resulting in the shielding effect of the mobile phone signal blocker for some mobile phone signals. shielding effect. At this time, if there is a spectrum analyzer on site, the technician can quickly find out which base station signal is stronger in such a live environment through signal retrieval, or analyze and determine which mobile phone frequency bands have no shielded signals. Complete signal suppression. Feeding this analysis result back to the manufacturer of the cell phone signal blocker will help to quickly find a solution to the unsatisfactory cell phone signal blocker.

2. In the field environment, the layout of the building is complex, there are many partition walls or obstacles, and the signal coverage of the mobile phone signal jammer is uneven. In such a field environment, if there is a spectrum analyzer, you can receive the shielded signal of the mobile phone signal jammer through the receiving antenna and display it on the spectrum analyzer, and then observe the waveform amplitude in each frequency band or read the signal. The strength value can accurately grasp the signal coverage strength of the shielded signal in each area, so that the expected signal shielding effect can be obtained in the corresponding area by adjusting the installation position or antenna orientation of the mobile phone signal jammer.

In terms of power consumption, the received signal is poor, the transmitted power is high, and the power consumption is high. There is one point that needs to be explained here, that is: the high transmission power consumes a lot of power in the mobile phone, but it does not mean that the low power of the mobile phone will cause large radiation. That is to say, it is unreasonable to say that "low battery calls have high radiation".

The CDMA IS-95A standard requires the maximum transmission power of the mobile phone to be 0.2W-1W (23dBm-30dBm). The maximum transmission power of a 4G mobile phone is 0.2W (23dBm).

The distance of the base station determines the distance of the mobile phone signal jammer. The closer the use environment is to the base station, the smaller the shielding range is, and the farther the use environment is from the base station, the greater the shielding range.

Cell phones have indeed made people's lives much more convenient and made people more dependent on cell phones. There are also many bad habits, such as B. watching cell phones while walking, playing cell phones while sleeping, and using cell phones for social activities. These are bad habits. Therefore, interference must produce a mobile phone, which is very important for your healthy lifestyle. Whether for organizations or individuals. But it also makes people more dependent on cell phones, and there are many bad habits. Walking and looking at your cell phone, sleeping with your cell phone on, and using cell phones as a social worker are all bad habits. Therefore, mobile jammers should be generated, which are very important for your healthy lifestyle. Whether for organizations or individuals. But it also makes people more dependent on cell phones, and there are many bad habits. One of the bad habits is watching cell phones while walking, going to bed to play cell phones, and using cell phones for social work. Therefore, it is necessary to generate a mobile wave disruptor, which is very important for your healthy lifestyle.

When we were together before, we always talked face to face. Now let's take a look at the phone screen. All kinds of social software have engulfed our lives. Don't forget to take photos every day, upload them to Facebook, or find out what other people are doing. Of course, it's common to use cell phones in classrooms and ring tones in restaurants, theaters, and churches.
There is no doubt that most offices need internet access, but what about cell phones? After some research, we found that 50% of managers believe that using cell phones in the workplace is not good at all. Using a cell phone at work will distract you. Therefore, please use a bluetooth signal jammer to shield the signal to improve the work efficiency of employees. Therefore, we need to take certain measures to make mobile phone use healthier and more standardized. Cell phone jammers have changed the way cell phones are used.
