Found on Ham Radio Online ( http://www.hamradio-online.com/ ), links to
some articles about frequency coordination at the poltiical conventions:
Political Conventions Ban Wi-Fi?

"...staffer for a publication covering the conventions, was told by several
authorities that Wi-FI interfered with “broadcast television signals” and
was thus banned."


"Tim noted that Electronic News Gathering (ENG) is a licensed — and thus
priority — use of a part of the 2.4 GHz band. ENG is used to send signals

Clicking to the paper cited in the WiFiNews article:
"Amateur radio frequencies that overlap 802.11b are 2.390–2.450 GHz and
5.650–5.925 GHz for 802.11a. They are primary from 2.402–2.417 GHz and
secondary from 2.400–2.402 GHz. A Notice of Proposed Rule Making (NPRM) has
been submitted to the FCC to change the 2.400–2.402 to primary.

Amateurs are very protective of their spectrum. The American Radio Relay
League (ARRL) is a powerful lobbying force in Washington, D.C. They are
very concerned about any unlicensed devices.

They think the original authorization of the FCC doesn't give it the right
to hand out the spectrum in this manner. You may find that the local groups
of amateurs agree and are helping with the ARRL's efforts. Getting involved
with these local groups to establish a dialogue will make it easier to
coordinate to minimize inference(sic) and conflicts."
