Isn't 800 MHz the preferred frequency band for both the bulk of
cellular telephones and public safety radio? And if you travel
outside of North America, isn't 900 MHz the preferred band for
cellular traffic? When you start getting into the Giggle Hertz
ranges, aren't you playing with things such as 802.11, 802.15, PCS and
a whole bunch of other mature services?

Just some thoughts.
