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... 850 is not that big a
difference from 900, nether is 1900 from 1800. Probably the 900 and 1800
bands was occupied in the us.
However, Ericson and Nokia are pushing GSM 450 for the 3:d world and the
most remote arias in richer countrys. So we might end up with the need
for 5 GSM band: 450/900/1800 for 'the world' and 850/1900 (and possibly
450) for 'parts of America'.
The part with lower frequency give bigger coverage is true. 900 reach
~twice as far as 1800, cowering ~four times the area. 450 will reach
~twice as far as 900, cowering ~sixteen times the area 1800 cover. Thats
the rational for GSM 450.
Hope the Neo1973 GTA2v4 will be released fast as possably as is. Then a
850/1800/1900 as soon as posably. Don't think a sales organization more
then the already existing one need to be built in north America before
the 850/1800/1900 version is ready.
If this is reconfigurable in soft/firmware... It's realy a quad band
phone... You just have to configure what three band to listen to. I Know
of no place having 850 and 900 in the same aria. I have litle hope for
that tho... It sounds like hw changes is needed :-(
