To see how effective this wifi jammer works I suggest you to check my video here

This jammer is so tiny you can fit into pocket. and carry it anywhere. it can powered through your power bank or 3.7v lipo battery. You can select which wifi network you want to jamm and attck on it . But be sure this is just for education purpose do not use for wrong purposes.

The 802.11 WiFi protocol contains a so called deauthentication frame. It is used to disconnect clients safely from a wireless network.
Because these packets are unencrypted, you just need the mac address of the WiFi router and of the client device which you want to disconnect from the network. You don’t need to be in the network or know the password, it’s enough to be in its range.

You can perform multiple attacks on this device such as you can jam any particular wifi network or you can do beacon spam or random beacon spam. or you can simple deauth all.
