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.
