Is there a map out there that shows (understandable to a layman like me)
where Cingular/ATTWS are deploying the 850 band?
I am in Lincoln, NE and have been told by the local shop that around here
Cingular does not have 850 and probably won't in the foreseeable future --
but inquiring minds would like to know about such places as Kansas City,
Denver, Des Moines, Chicago, which I visit sometimes.
The reason is not entirely academic-- I am considering whether a quad-band
phone is worth the expense.
Thanks,
Franz

Re: 850?
Franz,
See http://newarts.com/images/CoverageCompare.gif
I believe that subtracting the T-Mobile coverage (1900 only) from the
Cingular coverage (1900 & 850) may show the Cingular 850 coverage. Take
into account Cingular's broader brush.
T-Mobile is only licensed to use 1900 mhz & uses all available I think.

That is correct, however T-Mobile has the option of allowing its users
to roam on 850 mHz, but it doesn't allow it. It's like Sprint PCS which
roams on VZW analogue.

On HowardForums.com Mobilegirl says that this map:
http://people.ku.edu/~cinema/wireles...ws_800_850.gif
Shows all the Cingular TDMA 850 areas (they should be converted to
GSM.)
Dave
PS the map is consistent with the earlier suggestion of subtracting
T-mobile from Cingular.

However, the OP could be a using a 900/1800/1900 tri-band phone,
possibly because international roaming is important to him. If this is
the case, he would have to upgrade to a quad band to get 850 but keep
the other frequently used frequencies.

Re: 850?
According to Mobilegirl on Howardfoums.com the following map
http://people.ku.edu/~cinema/wireles...ws_800_850.gif
shows all Cingular 800mhz areas. Most should have GSM active by now.
Perhaps there are other 800 mhz areas that may be accesible.

True, he didn't say one way or another, but we can't make assumptions,
either.

Okay, I have no experience, I just know that when T-Mo commented on the
Cingular/AWS deal, it mentioned that it didn't even use the 850 band,
not even for roaming for the customers. In reality, I wouldn't think it
would matter as long as you have a compatible handset, but I don't make
roaming agreements, either.

Can't come up with a citation at the moment, but in one of the v600 reviews I
read last nite, the author said something about 850 being disabled in the phones
sold by tMobile.

I've heard that T-Mobile has the 850 frequency disabled on its phones.
However, in Canada, most GSM coverage is in the 850 band, so it would
seem logical that if all Canadian GSM coverage is available, then 850
would be available.
Any ideas?
