Why doesn't the FCC 'suggest' that cell phone and
PCS companies install some type of WiFi node at
every cell site in the country?

It's called Wi-Max (IEEE 802.16a) - it will have the range to do as you
suggest and YES THEY WILL do exactly that without being asked by FCC.
They're probably biting their nails waiting for Wi-Max to be 'actually
available' as opposed to 'coming soon'. Probably two years - it'll move
~very fast~ once it is started.

Wi-Fi doesn't have the range unless the user installs a very high gain
antenna. Some cities are installing Wi-Fi into (almost) every lamp post.
