CNet is reporting that the Pentagon and WiFi technology companies have reached an agreement intended to protect military radar frequencies while expanding the availability of WiFi.

This agreement will dovetail into the proposed additions to the 5GHz spectrum.

Those familiar with the spectrum will note that the 5GHz spectrum (used by 802.11a) is more prone to wall-penetration problems and other interference than the 2.4GHz spectrum used by the 802.11b (and g) standards.
