my local dealer rep told me that yesterday
thsi si suppose to happen by the end of this year

Not even possible. Your dealer is 100% wrong for sure.

Well, that's what AT&T announced when they started the 3G deployment: Top 100 markets by end of 2007 and entire network by end of 2008.

But we know the top 100 markets by end of 07 didn't happen so I have less faith in them being complete by the end of this year.

I wish AT&T admitted the whole 3G rollout has been a fiasco. It's gonna be 4 years since they started installation and they're not even 50% done yet! What's going on?

I wonder if the "entire network" also means networks that were brought online to prevent AT&T from losing their PCS holdings (mainly in rural areas) and networks that they intend to aquire, e.g. Unicel holdings in most of Vemont. The 100 markets is a realistic goal but the entire network?

Yes, as an AT&T employee, that is the goal.

Do you know when it will be reaching central VA (blacksburg/christiansburg/roanoke/lynchburg) area?

Do you think they might spend some time improving call signal (ANY)? We've been begging for this for years. I'd give up 3G just to get relaible signal, so every call that managed to get placed did not end by being dropped.

No don't know what is happening over there.

If you're talking about 3G, maybe the addition of 850 will help you. Or maybe you just using bad handsets

Well, if I were running things, I'd be having the teams assigned to remove TDMA gear also assigned to install 3G gear as they move around the country. That won't cover all areas, but it'd be more efficient, since I imagine a lot of sites are going to be visited as TDMA is turned down around the country.

When is TDMA supposed to be turned off this month?

what rural areas are you talking about?

TDMA is supposed to be off on Feb 18th


Posted by: Kevad007

Are we likely to see any major changes on the 19th? In other words, are there a significant number of towers that they have been preparing for this day, that once the time is reached, they can flip a switch and many of us will suddenly notice improvements to our coverage and singals?

It's possible. Just not likely with AT&T. I wish they would go ahead and finish because when driving from my house in the city to my lake house, calls typically drop because there is one tower for the whole are and capacity is almost always maxed out and my phone is at AMR-HR 4.75 kb

How do you know which bitrate your phone is on in AMR half rate ?

Cause I am an audiophile and can tell when the quality degrades alot. And also alot of times I go into Engineer mode of my LG and it tells me. I usualy force EFR though.

I'd be curious to see the output from the display showing AMR-HR4.75 vs. AMR-HR 5.15, 5.95 etc.

The difference between anything from AMR-HR 7.95 to AMR-4.75 is the payload vs. error correction, and not capacity (i.e. there's no capacity difference between a call on AMR-HR 4.75 and AMR-HR 7.95) The difference is purely payload vs. correction bits.

I doubt 850 will help much. And no we're not using bad handsets. They're fine when we travel outside the Hudson Valley. It's just here, where we work and live. Doesn't look like the Dobson takeover made an difference either.

Any where we can get a little real info? Hudson Valley NY has been suffering long enough. We need real signal we can rely on. Heaven knows we're paying enough for it! I didn't think cell service was a charity.

No, that is not quite right. AMR-FR sub modes include all AMR-HR sub modes. For example, both AMR-FR & AMR-HR can reduce voice codec payload down to AMR_4.75. Thus, AMR_4.75 could be AMR-FR, which has half the capacity of AMR-HR.

The relevant Wikipedia entry contains a handy table:

Here is a screenshot of a CU-500 in AMR where I am now. Signal is weak, HR is forced all the time.




Here is the same phone, in EFR, same location.:



Menu access is 277634*#* , * and # open and close the menu when you are on the main phone screen.

Personally, I want to see "AWB" TX 23.85 RX 23.85 someday......

I would imagine if this were a satellite phone, we would be seeing
"AMBE" instead, with a TX of some ungodly low data rate...

I think that I forgot to mention that I was only referring to payload on AMR-half rate... sorry for confusion.
The point that I was trying to get at is that regardless of which AMR-half rate codec is used, the overall amount of bits are the same... it just varies between voice and correction bits. The better the signal, less correction bits are needed
