Wifi is all the rage at the moment with just about every new laptop/PDA coming with it built in. Consequently Wifi security is a hot topic at the moment with people concerned about snoopers and how to stop people outside your buildings getting to your wifi networks inside. Granted you can line your walls with ali foil or such like but that blocks all electromagnetic emissions including mobile phones!
The UK Telecoms regulator ‘OfCom’ has commisioned British Aerospace (BAe) to solve the problem of stopping ‘Wifi’ escaping your premises or letting people outside in whilst still allowing mobile phones to operate. What’s even cooler about the solution is that the filtering can be switched on or off….for £500 a metre it’s only for the most security conscious!!!
