Value of GSM 850 coverage in N.A.?
|
|
|
| I have the option of a GSM tri-band phone with either 850/1800/1900 or
900/1800/1900 bands. I know that in major metropolitan areas I'm using
(T-Mobile) 1800.
What is the extent of 850 band usage in the US? Am I going to get that much
more useable area with 1800 and 850 vs just 1800?
Thanks,

You are far more likely to find 850 Mhz on the Cingular network than
the T-mobile network. Almost all of the T-Mobile network is descended
from Omni-point, PBMS, and Voice Stream, all of which is 1900Mhz
(1800 Mhz is NOT used in North America, the rest of the world is at
900/1800Mhz, The USA is mostly 1900Mhz because of history, All GSM
service in the USA was intially in the 1900Mhz band.
Cingular however involves a number of wireline operators (local phone
companies), who have 800 Mhz licenses that were AMPS/D-AMPS, so
coverage in some areas on Cingular is likely to be 850Mhz. Very
little if any of the T-Mobil system is at 850Mhz, because none of
T-Mobil's ancestors were wire line operators.

Thanks, Matt. That was the definitive determination I was looking for.

| Check Compass for the complete map of 850mhz coverage.

You will notice that all 850Mhz coverage is roaming, i.e. it isn't
T-Mobil themselves

Correct. T-mobile doesn't have 850mhz. Just roaming.
