T-Mobile LTE & Network Discussion V2

For GSM, here's what I saw this morning:

 

687

688

689

709

711

712

713

714

734

735

So are they making room for a GSM and lte channel or are they doing 2G refarming?

With EARFCN of 1025, you have a 5 MHz carrier, centered at 1972.5, extending from 1970-1975.

 

GSM channels, being 200 kHz wide, ARFCN 711 is centered at 1970 exactly, with 712 at 1970.2, 713 at 1970.4, 714 at 1970.6, 734 at 1974.6, and 735 at 1974.8. So we clearly have overlapping GSM with LTE, likely by way of selective resource block shutdown.

 

Oddly, UARFCN of 587 is centered at 1967.5, and Ericsson generally can reduce UMTS bandwidth to 4.2 MHz wide, which would be 1965.4-1969.6, though I have heard that Ericsson has recently matched Nokia in being able to achieve stable 3.8 MHz wide UMTS carriers. The reason this must be a 3.8 MHz carrier is because at both bookends, you have GSM carriers, at 688 (and 689) and 709 and 1965.4 and 1969.6 precisely.

 

So assuming 3.8 MHz wide U1900 carrier, 689 is still right at the end of the carrier, so something strange is definitely going on.

 

Either way, they're stuffing GSM into the LTE carrier (it looks like), which is pretty crazy and exciting.

10x10 MHz of B2 is live in downtown Jacksonville. No CA that I have noticed yet.

How are the speeds on it ?

That's really odd. Head scratcher.

 

T-Mobile has a TON of spectrum in Jacksonville, with 50 MHz of AWS-1 and 20 MHz of A block and 30 MHz of C block.

 

This 10 MHz carrier is using up the full A block.

 

In my mind it makes far more sense to deploy in the C block, even if just at 10 MHz, because you have the runway to get to 15 MHz wide.

 

They could easily have 1c U2100, at least 1c U1900, 5 MHz of GSM, 20 MHz L2100, 15 MHz L1900, and 5 MHz L700.

 

That's a conservative approach. Considering that they've been moving quickly to 1 UMTS carrier in lots of markets.

I got ~5mbps download on it the other day. This was inside the Everbank building.

Aren't they preparing to swap the C block with Sprint in the PCS swaps?

Nice! I wonder how el paso will be for t-mobile in the future. T-mobile also has tons of spectrum here as well.

Just tested it now (happened to connect to it.)

 

Much better today.

Oh wow they make T-Mobile new Jersey market look spectrum starved we have only 43 MHz of spectrum here...no AWS-3 spectrum purchased here

Wow - are there maps like these for other carriers?

San Francisco has a map with every RF antenna in the city. You can filter by carrier. https://fusiontables.google.com/DataSource?docid=1jgD0NwaO_dLNhIkjaANj_2fzV9WFwLDGgb8uM57x#map:id=3

 

Was last updated April 2015 though.

Does sprint get service out there or are they a FIT?

I wonder why they have not decommissioned the Nextel sites? Well they show they are decommissioned but why are they still listing them. Has sprint decommissioned them but have not removed the equipment?
