How to test a wifi jammer?

Admin Posted on 2022-10-19

The most feasible test method for the wifi jammer is a variety of mobile phone field tests. Using multiple mobile phones with multiple frequency bands to test the shielding effect of the wifi signal jammer on site is the most convenient, trouble-free, and feasible test method. Compared with the limitations of testing software through mobile phones, and the need for conversion after testing with professional instruments, this method is the easiest for users to master.

WiFi jammer test method

Prepare mobile phones with multiple frequency bands, including China Mobile, China Unicom, PHS, 3G, and 4G (it is best to have three 3G systems: Mobile TD-SCDMA, China Unicom CDMA2000, Telecom WCDMA), then turn on the wifi signal blocker, hold the For each mobile phone, test the effective shielding radius of the wifi shield from near to far from the installation position of the wifi jammer device. It is recommended that the user should test the shielding distance in multiple directions from the shield at the same time when testing.

When checking whether the mobile phone is blocked, it should be noted that you cannot just check the number of signal bars on the mobile phone, because the number of signal bars on the mobile phone is sometimes false, you should dial the mobile phone intermittently, you can try to dial the local toll-free number or fixed landline If the number cannot be dialed, it is judged to be still within the shielding range, otherwise, it means that it has exceeded the shielding range.

To test whether a certain point is within the shielding range, you should hold the mobile phone at this position for more than half a minute to confirm whether the mobile phone is shielded.

If the phone is unplugged from the non-shielded area to the shielded area, the mobile phone will be completely shielded after walking into the shielded area for a considerable distance. This is because once the phone is unplugged, the mobile phone itself has the ability to resist interference. This anti-interference will make the mobile phone adjust the transmit power by itself to ensure a normal call this time. Therefore, it is generally not recommended to perform dynamic testing in the call state, but to perform static testing at various points.

After testing all frequency bands, select the distance with the shortest shielding radius of a certain frequency band as the effective shielding radius of the wireless wifi jammer in this area. The location can be estimated based on this when large-area honeycomb layout is carried out.
