Default OK, so lets talk about the different protocols

Please Login to Remove!

As I stated in my other thread (OK, I am ready to switch phone carriers, I am ready to switch phone carriers. I would like to go to Sprint, VZN, or Cingular as I can get discounts with them, but I will go elsewhere if I can get the service I want.

Anyway, in addition to considering all of the different prices for service, I need to also consider the different speeds of the networks. If someone can list all of the different protocols (CDMA, EDGE, EDVO, iDEN, etc), and talk about the advantages and disadvantages of each. I would also like a run down on which is the fastest and which is the slowest (pretty certain IDEN is the slowest, with CDMA nearby).

Thanks in advance guys!!!

OH, and hey mods, this thread may be a great sticky somewhere once it is done. I searched, and couldn't find anything like this.

EDGE and EVDO refoer to data transmission standards. EVDO is supposed to be faster, but YMMV.

CDMA, iDEN, GSM refers to the actual protocol used by the device.

CDMA is mostly a North American standard.
GSM is the dominant worldwide standard, however, NA and Europe use different frequencies. Not too much of a concern anymore as most new phones are quad-band.
iDEN is also mostly NA. It refers to the protocol that allows PTT technology on the phone.

And do not forget all of South America uses the CDMA standard as well.

My experience is that with all the technologies (I have used all except iDEN), the call quality is clear as long as the network is available and not overloaded.

To the common user of wireless, that is the bottom line--clear calls, minimal dropped calls.

Have fun with the debate, though. I've engaged on-line discussions about this and never noticed a winner.
