In order to facilitate customers to use the wifi jammer better, this article will summarize some reasons that may cause the jammer you ordered to not work properly!
1. You have to order suitable shielding equipment according to your needs, which is more important!
1) If you want to stop the phone, you must choose a 2G 3G 4G full-frequency signal blocker. At this point, you must consider whether to add the additional features of GPS (satellite positioning) or wireless (wireless Internet access)!
2) Choose the right power supply: the portable wifi jammer has low power and is easy to heat, and the desktop wifi jammer has high power and good heat dissipation. The shielding range of the desktop wifi frequency jammer is farther!
3) If you want to stop GPS orbit, you need to choose a 2-in-1 jammer (low-cost 2G GPS jammer)) at least! Because when you only use a small GPS wifi jammer to block GPS, it automatically activates the built-in SIM card for GPS positioning.
2. After receiving the portable wifi signal jammer with battery (desktop jammer without battery), it must be fully charged within 6-10 hours;
3. All antennas must be installed in accordance with the signs (1-12-23-3 4-4 5-5 6-6 7-7 8-8 or GSM Global Positioning System). More importantly, don't open the protective cover without installing the antenna!
4. Interference range: Location signal strength = -75dBm. Interference distance will vary based on signal strength and location. If you are close to the signal base station, the interference effect will be poor!
