850Mhz is odd because north america is big.
Output power 2 watt versus 1 watt for 1900 Mhz.
To cover rural areas, less towers required for 850Mhz.
There will be more not less 850 support in the future.
Europe is much more congested so can justify more
towers with less output power on phones.

Not really true... Europe have GSM 900/1800...
They have two frequencies for different reasons.
1800 was added due to congestion on 900. In
North America 850Mhz is longer distance due
to higher output power. Read specs on cellular
modules (hardware) and you will see 850Mhz
is higher output power. That is why it is used
more often in rural areas. It can be hundreds
of miles between cities over here.
The level of confusion wrt 850 MHz is starting to annoy me, gotta jump
in.
There is *no* difference in range of 850 vs 900 MHz, or 1900 vs 1800
MHz. Both 850 and 900 use 2 watts, both 1800 and 1900 use 1 watt.
Stop claiming 850 is somehow better than 900.
The only reason USA picked non-standard frequencies was because they
had already licensed the 900 and 1800 MHz bands to something else.
