CDMA = Code Division Multiple Access GSM= Global system for mobile Communication GPS=Global positioning system
The better technology is hard to say. I'm not an expert. GSM is much older than CDMA. I believe that GSM has better coverage, but CDMA has an advantage when it comes to data transfer. GSM phones come with a SIM card. This sim card can allow you to change phones by taking out the sim card and inserting it into another phone. But, with that comes the problem of subsidy locked phones. I had a GSM Palm OS phone (a Tungsten W) It was locked to the AT&T wireless service, meaning I could not take it to another GSM carrier like T- Mobile or Cingular before the merger. Most all carriers lock their phones. Some will unlock them after a certain amount of time has passed. I think that I would go with the CDMA phone. Mainly because I believe, but am not certain, that CDMA has faster data throughput than GSM, and since your phone can do Web, email and SMS, you may want to utilize those down the line. Just using it as a phone you shouldn't notice a difference, except maybe the way the audio sounds from different compression methods. Clarity should be there with both. Opinion, Verizon-good, Cingular-bad, Sprint-OK, AT&T-Thank goodness they no longer exist. Brian O'Neal On Jun 24, 2005, at 1:14 AM, John Robinson wrote: Advise is needed. Today I checked with Verizon on a phone (Treo 650) and it's integration with a MAC. On the Palm website some of the features are only available for Windows, some for the MAC as well. I also checked with Cingular on the Motorola Razor phone, not as many features, but a very small phone. Here is my question for the group, as I had two stories. The Verison salesperson said that the CDMA network that they used is far superior to the GSM (I thought it was GPS, not sure) that Cingular uses. Once I got to the Cingular store they pointed out that the GPS was far superior to downloading of email, getting connected to the web, etc. then the older technology of CDMA. So once again I ask the advise of the experts. Which is the better technology? Will it matter if you are using it only for a phone? If you do what internet connection then would that make a difference as to which is better. Many thanks, I so appreciate the groups help.
