When you are doing wifi jammer coverage projects, customers often ask you what kind of environment can you assemble a good wifi signal jammer. Why can't the wifi jammer be used in some places, or the effect is relatively poor? ?In fact, it will be related to the surrounding environment, installation location, distance, and number of wifi jammers you use.
Under what circumstances is it less effective to install a wifi blocker?
No data analysis was done in the early stage, no plane survey, shielding cover plan, etc. were done, resulting in no effect after blind installation, poor shielding effect, etc. Professional installation advice and then choose a shielding device suitable for your own place).
Through the above information, you can know the range of the frequency band we use and the signal strength of the use environment (the larger the data, the worse the information is. It is generally recommended that the field strength of the installation location of the mobile phone signal jammer is above -86, and it can be used normally.) If you use Mobile card, or China Unicom card test data is the mobile or China Unicom data, the test signal strength needs to be tested separately by the four mobile Unicom Telecom, Radio and Television cards to be more accurate, take a screenshot of the professional information to the manufacturer, and give professional installation plan suggestions based on data analysis (if not Asking the place of use did not give you installation advice and directly recommend the product, just block it directly).
Do many manufacturers tell you that we are all four-network 2G.3G.4G.5G.WIFI signals fully shielded? In fact, WiFi is transmitted in many segments without testing or checking the technical parameters of the professional frequency band given by the manufacturer, which cannot be completely shielded. WiFi is divided into three segments (2.4G+5.2G+5.8G) with a bandwidth of hundreds of megabytes, which is why many customers It is said that there is a WiFi signal shielding but the on-site use can still be connected to WiFi and the reason why the video can be browsed on the Internet normally. Unprofessional manufacturers will generally express that they cannot recommend it to you better.
Whether many factories tell you that the jammers are different according to different signal strengths and different shielding distances, we can check through the software that there are base stations nearby where you use the wifi signal jammer, how many base stations there are, etc.
Information, using mobile base stations or Unicom base stations, telecom base stations, etc. can make an adjustment according to the information frequency of nearby base stations to enhance the signal strength of the base stations to be effective.
Shielding can be customized one-to-one service. Other factories are unified debugging and cannot be changed, resulting in poor shielding effect and intermittent use of mobile phones.
The installation height does not meet the requirements, the installation position is improper (there are obstacles), and the use of the partition wall causes the signal to be blocked and other factors.
Environmental factors, there is a base station 200-500 meters away from the location where the wifi jammer device is installed, which will cause the shielding to fail.
