Cellular Phone Forum / General / GSM / November 2003GSM Frequencies in the US for providers
Hello all, I'm looking to get a cell phone and have pretty much decided on Cingular GSM. However, I don't really like any of their phones (the only one they had I liked was the Samsung SGH-s307 and it was $250, more than I was looking to spend) Now I understand the basic concepts behind GSM/SIM cards. To the best of my knowledge, there are two requirements when selecting a GSM phone for use with a provider: #1. It be unlocked or locked to the carrier I'm using #2. It support the frequencies the carrier I select is using. Two questions-is there anything else I need to look out for other than that? But the real question is, can someone provided me the frequencies of GSM carriers in the US, at least Tmobile, Cingular, and ATT Wireless, and you're welcome to provide others. Thanks, Eric Kotz newsgroups@erickotz.com ... > #1. It be unlocked or locked to the carrier I'm using > #2. It support the frequencies the carrier I select is using.

You need not look at exact "frequencies", just "bands". In the US until recently ALL GSM was on the 1900 MHz band. Now some providers are starting on the 850 MHz band. Especially carriers who already had these frequencies licenced and these had been in use for analog or "TDMS" until now. There are only very few newer phones working on 850 MHz. If you just want a working phone for the 1900 MHz band, you will get an older Motorola Timeport (unlocked) at ebay for say 30 Dollars. Wolfgang > ... > [quoted text clipped - 19 lines] > > Wolfgang For the most part, it is true. Most GSM is in 1900. However, during the past couple of years, GSM 850 has been overlaid in many markets. If you decide on a phone that does not have 850 capability, you must remember that if you are in an area with 850 GSM, 800 TDMA, 800 CDMA, 800 AMPS, 1900 TDMA, and 1900 CDMA (but 1900 GSM in not avaialble), you will not be able to use to phone, not even to call 911. Cingular has a huge GSM 850 footprint. Many of the Cellular One companies are also overlaying GSM 850. Here is the Cingular GSM Nation coverage map. http://onlinestore.cingular.com/webapp/wcs/stores/servlet/html/Maps/Midwest_Grea tLakes/nation_GSM_map_6_30_03.htm Here is the T-Mobile GSM coverage map. http://www.t-mobile.com/coverage/national_popup.asp A good portion of Cingular roaming is on 850 systems. In fact, most of the new coverage of the American west (including North Dakota, South Dakota, Nebraska, Colorado, Wyoming, and Montana is an 850 system that is being built by Western Wireless. If coverage is important to you, Cingular may be your best bet. If minutes are important to you, T-Mobile may be your best bet. AD > For the most part, it is true. Thanks.

If looking for a GSM phone based on SIM identity it will be of no help to have coverage in one of the NON-GSM techniques. > A good portion of Cingular roaming is on 850 systems.

Its quite a problem for me to see, where there is coverage in the the 1900 or the 850 MHz band. But this is of great importance for international roamers like me, who do have 1900 MHz but NOT 850 MHz capable phones.

At present there's already several "quad" band phones from companies such as NEC, Motorola and Handspring. Years ago it was not common for all European phones to be bother 900 and 1800 and now it's just common that all new phones introduced for Europe are capable of both 900 and 1800. - - - - - - - - - - - - - - - - - - - - - - - - - - To send an email reply send to GSMthemobilestandard (@) yahoo.com Il giorno Tue, 11 Nov 2003 09:46:08 -0800, Group Special Mobile <look@signature_to.reply> con una bandiera della rinata Fiorentina in mano e lo striscione "Meglio liberi all'inferno che schiavi in paradiso" nell'altra cosi' parlo': >Perhaps not now, but I wouldn't doubt that in future years this will >be the case. i hope so :-) > At present there's already several "quad" band phones >from companies such as NEC, Motorola and Handspring. yes but we need "five" band phones now... in italy, f.e., UMTS is already going (not so well, but it is present :-) ) >Years ago it was >not common for all European phones to be bother 900 and 1800 and now >it's just common that all new phones introduced for Europe are capable >of both 900 and 1800. this is true, but now we have a lot of new things... and I'm not so sure for the future of "quad" band phones in Europe...

In the future we will probably see a phone that is capable of working on any technology, and only the frequency will be a determining factor of the phone. It will probably be all done with a card similar to SIM, if not a next generation SIM.

Probably why GSM didn't take off in the US in the first > place because they didn't invent it. > > 73 de Simon, VK3XEM. Actually, Americans like feeling superior over everybody else. Most Americans will argue about how CDMA is the best technology, and how European GSM providers are moving to CDMA (W-CDMA). They will then argue that national providers such as Verizon Wireless, Sprint PCS, and Alltel already use CDMA (CDMA one, CDMA2000, CDMA2000 1xRTT). The thing they don't know is that CDMA2000, CDMA2000 1xRTT, and W-CDMA are not all compatible. Yes, CDMA2000 1xRTT is backwards compatible with CDMA200, but neither of those are compatible with WCDMA, a system prevalent in Japan and taking hold in Europe. If I confused the heck out of you, just ignore it. It's not worth losing sleep over the technicality of this post. Basically, if you have a CDMA phone from the U.S. it will not work anywhere else in the worls except Canada, Mexico, and maybe Australia/New Zealand. AD >Americans always have to be different! 850 MHz GSM is not used anywhere >else in the world. Probably why GSM didn't take off in the US in the first >place because they didn't invent it. Why is it that anyone who sees something different automatically assumes that the difference was done out of spite rather than for a good reason? It's BS that GSM didn't take off in the US in the first place because it wasn't invented here. GSM wasn't invented in Asia or Africa either but it was adopted. Your remark is nothing more than Xenophobia. Twenty years ago the US had a working compatible mobile system.

It's sold only by AT&T, however. An updated version - the NEC 525 - has been announced. The quad-band Motorola V600 is coming out right now and can be obtained unlocked, though the prices are slightly astronomical.

You have the understanding of what you need exactly. The only thing that may "confuse" the issue for you is if you opt for cingular in areas other than in WA/CA/NV or NC/SC and eastern TN those areas use only GSM 1900 whereas other cingular areas are likely using GSM 850. If you are in one or the other area it will determine what is compatible GSM in your area. All US GSM carriers use either GSM at 1900 Mhz or GSM at 850 Mhz and sometimes both. ATTWS uses 1900 in all their coverage areas. They also are introducing 850 in addition to 1900 where they have 850 licenses. cingular uses GSM 850 extensively and perhaps when completed will have more 850 coverage than they do 1900 coverage. - - - - - - - - - - - - - - - - - - - - - - - - - - To send an email reply send to GSMthemobilestandard (@) yahoo.com |
