The most basic primer ever to how a cell phone works.
AD article continues below...
Have you noticed once people have acquired some expertise on a subject, they talk about it as though everyone should know as much as they do? And if you don't understand what they are saying, some of those people are not nice enough to explain it to you, belittling you instead? People who know about cell phones are not necessarily geniuses or geeks. They do not have any special powers that bestow technical knowledge upon them. They've simply been around cellular technology long enough to have picked it up.
Now you don't have to spend years around mobile phones just to understand how they work. We've broken it down in plain English so that the next time someone goes spouting off about CDMA 2000 1xRTT or some other obscure cellular acronym, you can join in the conversation with confidence.

Happy to Help
Put this on the main website!!!
FINE, fine piece of work, that Primer to Cellular Networks. PUT IT ON THE MAIN SITE, off to the left, with the other links! Man, this is the kind of stuff that I DON'T want to have to go hunting around for--dude, I'm BACK to dial-up, because I can't afford DSL--when I'm surfing.
I found the site via Jim Karpen's Web Guide at PocketPC Magazine http://www.pocketpcmag.com/newsl_JKWG/webguid e.asp?id=273, and I was elated. This is the kind of stuff I need: short, concise and to the point. You did it well here, Eric. Thank you very much...BUT PUT IT ON THE MAIN SITE!!!
Hey, thanks again,
Come on, guys. Keep it consistent, and put this link on the left-hand...
the second is that we are bumping our spectrum primer (we're still doing it, but just not first) in favor of a more thorough explanation of gsm and cdma - how each works, what each is capable of, where each is heading in the foreseeable future and where each is available.
this comparison should answer many of your requests and questions, which is why we haven't really been answering them here.
Great overview. I'd like to dig deeper into spectrum use technologies (protocols, compression schemes, etc.) What are some references (books, sites) that you find useful?
Excellent, Educational, Easy to Understand Article by Eric Lin
Now my question, which has practical consequences regarding our choice of cell phone to buy:
I understand that upgrading GSM (Cingular and T-Mobile) will be more costly than upgrading CDMA/SPC (Verizon and Sprint).
If that is true, it stands to reason that the CDMA upgrade will progress faster than the GSM upgrades.
The ultimate projection is that CDMA > EV-DO > EVDO Revision will be more widespread than GSM > WCDMA/UMTS > HSUPA & UTRAN LTE and will happen at a faster rate, because it will cost Verizon and Sprint less to implement. More Verizon and Sprint people will be enjoying their "bigger/faster" soone...
BTW, whoever decided to call it WCDMA should have realized that it would be perceived by laymen as a CDMA rather than a GSM upgrade. I think that they should have used only UMTS, which doesn't mislead.

Taking the time
Excellent article - thanks for taking the time to do this...
Again - this was a superb intro and anything else is gravy and very much appreciated.
Thx as well for maintaining this whole site - even though I'm not involved in the industry per se', I have an active interest in technology and manage all the cellular devices for our company and this site is one of my main sources of information - it's a huge help.
