What exactly does this mean? Is it an open forum to ask questions?

Pretty much. People go there and say IamA _____ AMA (ask me anything). People have already asked about LTE, refarming, his thoughts on the merger, among other things.Originally Posted by MrObvious

If anyone can post for me I would appreciate it. It won't let me register and I wanted to know when 1900 MHz UTMS would be in Wichita.

Looks like a few people have asked about 1900mhz and getting not much of a response.

Very cool read, here are some of the highlights:

We're using the new spectrum to support the LTE roll out.
We support roaming onto AT&T's UMTS 1900 network in some areas, as long as your phone supports it. Data is capped at 60 kb/s though, so it's not particularly useful.
(nerdtalker is Brian Klug from anantech)Question (nerdtalker):
First, I have to note that I'm a huge fan of T-Mobile, purely because of how quickly you guys roll out WCDMA updates. You guys were first to deploy 64QAM (HSDPA 21.1), and first to deploy DC-HSDPA in the USA, while meanwhile AT&T continues running 16QAM in most markets with no public plans to move forward. At some level I view T-Mobile as the only real GSM/UMTS carrier in the USA thanks to that commitment.
A couple of things I've always wanted to ask:
Can you talk briefly about how much traffic on GERAN you see from iPhone customers? How much of a catch-22 is that situation for moving that PCS spectrum dedicated to it over to WCDMA?
In some markets it seems as though T-Mobile will be unable to run DC-HSDPA on AWS alongside any LTE because of lack of spectrum. Obviously multi-band carrier aggregation (WCDMA carriers on PCS and AWS) is a big part of that future, can you talk about the challenges involved there?
Will T-Mobile deploy 3GPP Rel 8, or will you guys go right to Rel 10 for LTE?
How much variance in WCDMA utilization do you see across markets? From your point of view, are caps and the end of unlimited data plans really backed up across the board, or just in a few markets? In my AZ markets (Tucson, Phoenix) where I do a lot of testing, I am regularly find I have the sector to myself.
Traditional PA at bottom architecture, or Remote Radio Head architecture for T-Mobile LTE?
This is already somewhat obvious, but could you confirm/discuss T-Mobile LTE channel bandwidths?
Answer (tmo_engineer):
We have about a million iphones on our network now. 99.9% of their traffic is 2G/EDGE only right now, so obviously their load is dwarfed by everything else. The iphone is a significant part of the modernization project. Once implemented, iphones will work on U1900 at much higher speeds.
Spectrum is always a limitation. With the software that exists now, you will not be able to do dual carrier split between AWS and PCS. That's supposed to be fixed in the future, but I don't know a timeline on it.
It depends on a lot of things. In general, I think caps are stupid, especially the way that we handle them. Events (concerts, sporting events, malls @ Christmas) crush us though.
We're going with remote radios as much as we can, for LTE, UMTS, and GSM.
LTE will launch with a single 10 MHz channel, 5 up, 5 down.

Not my market, but we also had a bear that once bit into a transformer and fried itself.

Yea not much info in that thread other then it seems T-Mobile is targeting the refarm to be completed by Q4.
