Many offices still rely on wires, despite the savings a wireless network brings. There's no need to install and maintain cables, and it's no hassle to connect new devices. Maybe it's because of security concerns. Berkley University showed that Wired Equivalent Privacy (WEP) is a misnomer, vulnerable to snooping.

But Intel has shown way back in February 2005 that a completely wireless and secure office is possible. Even phone calls are handled wirelessly. A test setup involving 25 people proved the feasibility of the concept. The model deals mainly with workstations, but it's easy to see that smartphones and PDAs can also play a big role.

There's a PDF on Intel's website that discusses this in further detail. Thanks to BizToolBelt for the heads-up.
