WLAN pocket killers device
The public library offers a great service with its free wifi Internet access open to everyone who walks in the door, but you're spot on with your concern about privacy and safety. A wireless network with a password is safe, except if everyone knows the password then you're all in that digital room together. A network without a password, just an agreement screen is even more insecure because now even people in the parking lot or building across the way can be sharing your digital connection! That's why we need to use a WIFI jammer. Each wireless device sends signals on one or more frequencies. Whether you're going to the library to study or have a cup of coffee, bring a jamming device to ensure that your smart device won't be hacked. To drown this signal out, you'll need to operate on the same one. Look up the name of the device you're trying to jam, or use this guide to WiFi frequencies.
