So are there going to phones that operate at even lower frequencies than 700 Mhz then?

Absolutely. Lower frequencies penetrate water bodies (trees, leaves,
people) as well as walls, and thicker metal sheeting.

Give them time, and somebody will come up with a proposed usage.

Right now, the public band around 450 MHz is voice only, with rare
exceptions. Police, fire, and other like services are using that. But
above and below, across the TV spectrum, I don't doubt somebody will try
to find a use for any and all of the newly available space. Especially
if it makes money for the FCC, selling that spectrum.

Let's worry about what we already know is being developed and rolled out.

Thanks for your response Stewart! So are there antennas at police and fire stations putting out this frequency 450 MHz?  Loni

Edmund, OK is getting a petition going  to stop wireless transmitting smart meters in Edmund, Oklahoma. 
 
Hooray!

Hi Loni,

Back in the late 1990's I got a scanner to keep from being bored, and I
got a book /Radio/ /Call/ from Radio Shack that lists every public and
corporate radio registered with the FCC, plus walkie-talkie frequencies,
pagers, trains, you name it.  It's a thick book. Then there are ham
operators and shortwave radio. The world is really awash in RF EMR as
compared to over a century ago.

One of the 11 bands the scanner covers is a public band between 450Mhz
and 470 MHz.
Usually the transmitting antenna is up high, on one or more towers on
the highest hills of the county.

Hey Stewart!
 
So those frequencies are more penetrating to the walls of anything and must be everywhere as well. Loni

Yes, But, they are not On all the time, like masts and WiFi are.
Also, all the old radios are analog. Some of the police units are
upgrading to digital for security.
