How to secure your wi-fi

For IT savvy people you know how you can secure your wifi network, and restrict it to only you and anyone else with permitted access to use it, but for others who doesn't know how to setup up these, for those who just use the wizard to setup by just clicking next next next finish, there is yet another solution, the anti wi-fi paint.. o.0

Researchers at the University of Tokyo in Japan have created a special paint which can block out wireless signals. The paint, which could cost as little at £10 per kilogram, contains an aluminium-iron oxide which resonates at the same frequency as wi-fi – or other radio waves – meaning the airborne data is absorbed and blocked. While paints blocking lower frequencies have been available for some time, this new technology is the first to absorb frequencies transmitting as high as 100GHz (gigahertz). Signals carrying a larger amount of data – such as wireless internet – travel at a higher frequency than, for example, FM radio.

The paint has a number of interesting potential applications including: keeping wireless networks secure, blocking phone calls during movies, shielding hospital rooms from unwanted electromagnetic radiation, and making clothes that protect people from electromagnetic waves.
