Cingular Killing Beyond Wireless TDMA March 31st

Why should they keep TDMA? It's a dead technology with very few users any more. Sounds like a solid decision.

 

More bandwidth for GSM and UMTS ... Nice to see that starting to happen.

Not to mention it wastes bandwith.

 

I agree. TDMA really does need to die for the networks to move on.

I have been wondering this. My grandma is still on TDMA, But I've been talking to her about letting me add her to my plan.

She's still using the old Nokia 5165. I don't think she's under a contract anymore tho... Just kinda idling by.

yeah but everyone else is right........we have to move on......GSM/GPRS/EDGE and UMTS and UMA are the way of the future......we need to do some spring cleaning on the "spectrum" and this is the time to do it

 

Ok, I will give you this, that in GSM vs TDMA, TDMA uses less bandwidth per call. However when you compare how much bandwidth is dedicated to TDMA, and how many users are on it vs GSM's bandwidth allocation & how many users are using that bandwidth, once comes to the conclusion that the bandwidth would be better used serving GSM customers.

at last its not all about facts or rumors but about logic.......like i said......spring cleaning

 

Because there is a minimum amount of bandwidth that has to be set aside just to have an operational network on TDMA. They have already cut the TDMA to the limits, and coverage is already suffering in some areas. The only way now to get more out of it is to shut it down.

sorry i disagree, tdma uses far mor band width than gsm.:loony:

 

you can add her to your existing family plan and she will be included in your group and share your minutes... she will get a new phone and retain her number...if you do not have a family plan you can change to one...... in either case you have to have the number txferred into your name to have it added to your billing acct...also her phone number **has** to be in the same market as yours to be in a family plan... if she is not in the same market as you ... you may find it les expensive (pending how much she uses the phone) to switch her to prepaid service... 25 bux will get you 100 minutes with a 90 day expiry... no access fee and no contract

 

yeah..........you could also simply add a line to your account with a number from your area......then give her the phone........this could be bad though if your grandma doesnt live in the same area because if people who live near her want to call her on her cell.....depending on how far away you live.....it could be regional long-distance or national long-distance...

Where is yours?

GSM does use more bandwidth, but can support more users per channel and has a much higher audio bitrate.

I think that is a great idea to cut out TDMA.... Its a dead tech. I think that as soon as Cingular dose this it will make their network(GSM) even better than it already is and thats because then they can allocatre all of their spectren to GSM and its New Tech. I remember back in the day when AT&T ruled, and the reason why they did was because they did dedicate every bit of spectrem they could to their "Digital TDMA" tech. that is why imhop they never dropped a call. Once AT&T started to add GSM all over their network many of its customers started to experince dropped calls and calls that constently broke up. The reason why i believe is because they didn't have enough spectrem to support at that time all 3 tech.(mainly only 2) If Cingular turns off TDMA and Analog, think of how much better the call quality will be!!!!!! I can't wate!!!!!! But what i do think Cingular should do is overlay GSM on every tower that they transmit some sort of wireless signal off of. Weither it be Analog, or TDMA. That way they have the best coverage!!!

 

since im the dreaming, according to you, why dont you do a google serch. after all youre the one doubting me.:lmao:

 

There's no need to do that, I've already linked an article on TDMA vs GSM. Scroll over a few posts.

-Jay

 

don't get too excited....wat your suggesting is very pricey and very painstaking in labor and time......to overlay Cingular's "AT&T Digital TDMA" with new GSM towers is a very big task considering the size of the actual TDMA coverage......they are overlaying every day....thats wat they do....the TDMA coverage covers almost every part of America......they always strive to blanket America with spotless coverage.....so they are in all essence doing wat your suggesting already just not as simply as you put it

 

I'm just wondering but, isn't TDMA the base for GSM?? I thought I read this in post somewhere.....

 

I'm pretty sure that thats a correct statement. I'm pretty sure its right anyway, because I remember reading somethinglike that somewhere.......old technologies like TDMA and AMPS were the base for todays technologies...

i remember reading that iDEN was a combo of CDMA and GSM

 

This is where the misuse of words becomes an issue (Not aimed at you SC).

The TDMA that most of you refer to is really D-AMPS(IS-136). TDMA is just a method of cramming more users onto one frequency. TDMA itself is used for iDEN, GSM and DAMPS. They way it is utilized by all three is different, but the underlying TDMA principles are the same.

SC, iDEN is a combination of TDMA and GSM.

 

The evolution of cell phone technology.....

AMPS to TDMA to GSM to iDen to CDMA to 1x to Edge to EVDO to UMTS/WCDMA to FDMA?

If I am wrong correct me. But I believe this is the order from oldest to latest and greatest....

I might be mixing in the data with the voice, but it still should be in order....

EDIT:
oh wait....i think fdma is just as old as tdma....

 

You're intermixing timelines of unrelated technologies.

On the current GSM carriers the timeline would be
D-AMPS->GSM/Edge->UMTS

On the CDMA Carriers
AMPS->CDMA/1X->EVDO

iDen, well, that's all it is. There haven't been any changes to the basics of iDEN since it's inception. WiDEN never really took off.

Principles of FDMA are used by almost all the past and current cellular technologies. Everyone is using it in conjunction with a parent technology.

 

Yes I am mixing them. GSM is an older technology then CDMA. I'm just going by when they came out.

I guess "to" wouldn't be the right wording...
