I don't get any cellular service at my house with AT&T. I wanted to switch to T-mobile, but my friend said service would be the same since they all have to use the same GSM network for the T68m. Is this true?
Posted by AldenC
No this is not true. In the Washington State market there are 3 separate GSM networks. AT&T, Cingular, and T-Mobile. Each company has built their own network. I would choose Cingular over T-Mobile because of the capacity problems that T-Mobile has.

Okay thanks!!!

This is a big problem in the US because the FCC set the United States' GSM at the 1900 MHz bandwidth. Being that we are operating at that high frequency, coverage (especially indoors) is going to be a bit shady. I've heard that eventually we will be using the 850 band for GSM, but I assume that won't happen for years down the road.

What frequency does GSM in Europe use?
I assume that's why analog works everywhere? Because of the lower frequency?

900MHz and 1800MHz
lower frequencies have better range and can work it's way through objects (houses, trees etc) better than higher frequencies....

Do some of the providers share networks or towers?

Thatīs right! Try to make a call in woods with E-Plus or o2 Germany outside the cities; itīs hard to get any network connection! They use 1800 MHZ!

Only o2 Germany uses national roaming w/ T-Mobile Germany! Towers are shared as well, but only in difficult places, e.g. highways, airports,...

When GSM-850MHz becomes extensively deployed in USA it will be used particularly in rural areas. 1900 will still be used in cities because of its greater capacity. So most US GSM networks will become dual-band like major European ones, although some are still either 900 or 1800. In the fall of 2003 Motorola will launch a quad-band flip-phone;a must for those of us who, besides the 1900 that we use when we shop at Bloomingale's in NY,need to keep in touch when we ski in...Wyoming or Montana!;-)Just kidding!

800 and 850MHZ is workin now... they're experimentin.

I know about GSM-850 but I have not heard about 800. Can anyone comment?
Posted by 701
Same thing as the 850mhz-the range is NOT fixed,is between 800mhz and 860mhz
Posted by haki
Are you sure that this is not the so-called 850 band? I cannot handle the prospect of a fifth gsm band!:-(

You guys in the US are so far behind with your technology!
Posted by haki
That is why they have wonderful CDMA networks with GPRS operating at 144mhz, and an excellent iDEN network! Not to mention the rates, regardless of the per min charge which is offset ay the nearly free charge to call a mobile locally!

800 and 850 are the same thing. GSM service on the 1900 is that strong but it will be just as strong as CDMA if your provider is planning on deploying UMTS (WCDMA). The only company so far to announce that service is AT&T Wireless. One other benefit to the technology is the data speeds will be 2.4MB/S

actually Interwave has already deployed an 850 mhz GSM service in Alaska. The Motorola T720 for GSM service is equipped with both the 1900 & 850 mhz bands of operation
