Primer: Intro To Cellular Networks

This article is a great introduction to how mobile technology works. But, I am a rep. for Cingular, Verizon, Sprint, TMobile, and Cricket. I have customers every day who might need a little more "down-to-earth" explanation. It's true, CDMA carriers like Verizon and Sprint are blowing GSM carriers away right now as far as data is concerned in the US(until UMTS is widely available), but a very large portion of wireless consumers don't care about data (b/c they don't use it). From my experience, I have learned that most customers are more concerned about overall coverage. This concern can be easily handled by finding out what areas this person travels too. Obviously, CDMA networks have more digital towers plus analog capabilities (on cert...

Hello Eric,

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,

Starkman

everyone who has responded to this primer so far, thank you. two big things will come out of all your responses. the first is that we will directly link terms in our glossary to their first appearance in this primer, so future users will immediately be able to click and learn more about terms that we don't spend much time on in the basic primer.

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.

Eric,

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?

Thanks.

Doug

You have provided us with a very clear, logical, well-presented education here and I appreciate it a lot. Thank you!

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...

That was a great article on the basics but how about a few that concentrate on the different technologies, maybe go in-depth into GSM or iDen and CDMA, explain their advantages, disadvantages, and their future paths. Will the technologies be obsolete in the near future or will they be around in one form or another in 20 years? Again, thanks for the article.

Thank you Eric for taking the time to address the gap in knowledge between the veteran cellular soldier and the inexperienced cellular civilian. It seems, all too often, that, here on phonescoop, an earnest interest in the world of mobile technology is met with either a bitter elitist attitude or childish squabbling and biased propaganda from the fanatics associated with each carrier. Sad to say, most people would rather give up on trying to learn rather than wade through the murky waters of cellular angst that fill the forums. It is refreshing to see a clear and knowledgeable explanation free of lop-sided fanatacism and bickering. Please continue to help those who wish to gain a clear understanding, and help the rest of us to follow in ...

I would like to echo the request for more "objective" data on the various technologies (capacities, power outputs, range discussions, building penetration etc.) as well as some objective stats on the different networks (total number of towers, number of towers on various technologies etc.) - if this kind of information is even available.

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.

...is definitely a good move. Nice job, Eric.

thanx for the article eric lin.. i found it to be informative as always... keep up the good work, it is appreciated




p.s first post, alright!!
