Talk:Comparison of mobile phone standards

message: Hey guys, just wanted to thank everyone for the "cocktail party" analogy explaining the difference between TDMA and CDMA. I am by no means an expert on modulation technologies, but I've made a good living as a technical writer, and that was one of the best analogies I have ever seen in my life. Thank you.

thread_title:  Vandalism 

message: It doesn't seem to follow that CDMA uses less power than GSM.  GSM phones are almost invariably smaller than equivalent CDMA phones, and have longer talk and standby times.  My coworkers with CDMA phones are amazed that I can go a week or more without charging my tiny little phone, and can talk for 4 hours.  If the article is saying that CDMA cell 'towers' use less power, then that should be made clear. ~19:41, 7 December 2006 (UTC)
thread_title:  Power consumption 

message: I have deleted for the second time something about how the iPhone is being released for GSM only so far.  I don't think this is the right audience for this kind of sour-grapes stuff, so I have removed the specific mention of the iPhone again.  Instead I mentioned that features come later to CDMA phones.  I don't even think THAT is true, though -- CDMA has been leading the charge in high-speed data, and I'm pretty sure they were the first to have GPS functionality in their phones.  
:As an aside: The fact that the American phone companies can't seem to deliver the PRODUCTS is another issue entirely *grumble*.  Here's some sour grapes of my own:  Maybe if Apple would have chosen CDMA, they would have been able to have decent high-speed data with good battery life on their shiny little toy.
::Well, Apple now also launched the iPhone on time for the holiday season 2007 in European countries like the UK or Germany, expected in France soon. They hadn't been able to do so if they had chosen IS-95, which is never heart of in most parts of the world. Since Apple wants to gain market share aggressively, GSM is their only option.--65.241.15.227 01:39, 10 October 2007 (UTC)

thread_title: IS-95 and the iPhone

message: iPhone and other GSM users will be able to use their handsets in Air France's inflight full mobile phone service:
http://corporate.airfrance.com/index.php?id=communiques_detail&tx_ttnews%5Btt_news%5D=2699&L=1&no_cache=1
CDMA phones will not work.
Flight companies of course will select GSM, because they target over 80 % over their global flight guests with it.
So if I want my device to work in airplanes, I better follow Apple and build a GSM device.

thread_title: Network Effect

message: Under cons of GSM, it says that it interferes with audio devices. But then it says "3G uses W-CDMA now." How is that relevent?? Fresheneesz 02:07, 20 August 2007 (UTC)
replies: text: TDMA signals turn on and off about 50 times a second.  This shows up as a 50hz noize in unshielded electronics -- especially amplifiers.  CDMA signals are always on, and so they do not interfere in this particular way.  Many people consider that particular interference to unique to GSM.  It isn't.  It is a feature of TDMA, and when GSM moves to its next generation, they will no longer be using TDMA, and GSM phones will no longer cause that terrible noise.  Does that help? --Mdwyer 17:01, 20 August 2007 (UTC)

thread_title:  Need to add AWS 

message: It lists "Capacity is IS-95's biggest asset; it can accommodate more users per MHz of bandwidth than any other technology." Is there any documentation to back this up? At least on spectral efficiency it is not true. Also WCDMA with CS over HSPA can offer significant increases. Seems that it's more of a marketing claim without any evidence provided in the article. Facts/figures? Anyone?  Nasula (talk) 09:51, 18 January 2011 (UTC)
thread_title:  IS-95 benefits? 

message: As the last NMT network in Scandinavia formally closed down 31 December 2007, and as the network in practice had lost all but a few subscribers to GSM already 15 years earlier, I think the NMT column should be removed from the table.Thomas Blomberg (talk) 02:08, 15 February 2011 (UTC)
replies: text:  I disagree. Reason: it was a 1G technology and as the most widespread of the 1G technologies, gives a viewpoint into the evolution of the standards via comparison. Nasula (talk) 07:08, 15 February 2011 (UTC)

For example GSM/UMTS allow voice and data at the same time while CDMA2000 do not until SVDO is implemented:

thread_title:  External links modified 

message: The table is very good, but I feel it lacks important (to common folk) information like theoretical/real up/down-load (or up/down-stream) speed, frequency and range. And it's missing transitional generations like 1.5G, 3.9G etc. Also, for each one whether repeaters are possible (not clear to uneducated) which is quite important from the monetary standpoint. I started dabbling out of curiosity, but I am way over my head. Information I found sometimes seems contradictory, sometimes similar but different terms are used for the same general meaning... I feel I would need a degree to finish the table. So I hope someone in the know could expand the existing table with this. Setenzatsu.2 (talk) 00:07, 10 April 2023 (UTC)
