Thursday, December 23, 2004 Tuneable windows

From Design Engineering 12/16/04
"Secrets that zip across offices through wireless computing networks are all to easy also zip through office windows into the hands of ones competitors.
But now researchers at the University of Warwick have come up with a solution to the problem. They have devised a method of producing tuneable surfaces that can selectively block signals from wireless networks from spilling out of the office."
I've reported on this before but the tunability of this application really makes a huge difference. The other applications were installed in walls and (I think) were just wideband. This is problematic if you want to allow a pager, just not ____, for example.
