Jammer B54 is a professional device, designed to inhibit the most common WiFi Radio Frequencies. It’s a very powerful jamming device that can be used either for indoor or outdoor use. The most known WiFi frequencies are 2.4 GHz and 5GHz.
Unlike any other WiFi blocker, jammer B54 jams both 5.1 GHz ~ 5.9 GHz (therefore rendering it a fully-fledged 5 GHz Jammer) and 2.4GHz ~ 2.5GHz frequencies: such frequencies are currently used by most routers and video surveillance devices. Most drones are controlled by remote controls, which deploy 2.5 GHz.
As you can deduct from the pictures above, it’s definitely a desktop jammer, therefore it’s not portable. Given its output power and size, it can easily cover a considerable range between 50 – 60 meters.
