Wi-Fi Blocking Paint

We know that Wireless LAN (Wi-Fi) is riding on non-licensed bands of radio frequencies. It is unavoidable, especially in a metropolitan area, that our facilities are filled with un-wanted wireless LAN radios.

With new strong encryption, we do not have to worry about the information leakage. However, we DO have to worry about effective transmission throughput. The more users in the same channels, the less effective throughput can we get!

It would be very helpful to block those un-wanted radios from entering our facilities!

We learn in high school that "Electromagnetic shielding" can block radio signals. In real life, is it feasible for us to build a "metal cage" around the room, as mentioned in most textbooks?

If the following "Wi-Fi Blocking Paint" is ready, it would be a great solution to above problem.

Isn't it a great idea?
