Band 25

• EARFCN 8640 (downlink) [10x10] [PCS C/G Blocks] [dkyeager 8/17/15 screenshot] 1990
• EARFCN 26640 (uplink) [10x10] [PCS C/G Blocks] [dkyeager 8/17/15 screenshot] 1910

 

 

The first person to find 10x10 in the Columbus market was nowerlater on 8/3 http://s4gru.com/index.php?/topic/4742-columbus-market-mapspreadsheet/page-193#entry434099.  It has also been found in the Indianapolis, Cleveland, and Seattle markets.

Wonder if Its possible For that area to see 10x10 then?

They would have to expand the second carrier to do that because I don't believe sprint has the PCS C5 block in Des Moines...

this is correct, we don't have anything next to the G block here so they would have to eat into the B block more to expand the 2nd B25 to a 10x10. would be nice though because we would then have a 10x10 and a 5x5, but i don't think they will be able to refarm that much CDMA/EVDO anytime soon.

Yea probably not.

Shows what I know. I thought they could just take the 2 5x5 and, make them one 10X10.

The spectrum has to be contiguous to do that. The B block and G block are not aligned next to each other, so there is no way to combine them. That's why there are only limited markets with a 10x10 carrier right now.

Not sure if this is the right place for this question, but I was wondering why TD-LTE carriers are 19.8mhz apart (198 difference in EARFCN) when they are 20mhz each.  Shouldn't the center frequencies be 20mhz apart (200 difference in EARFCN) to avoid interference?

Nope.  The subcarrier occupied bandwidth of an LTE carrier is 90 percent of its total bandwidth.  The other 10 percent is used for unoccupied internal guard bands.

Oh so rly only the guard bands overlap.

I am unsure what you are posting, but this appears to be some sort of log output.

 

You have two 20 MHz TDD band 41 carriers:  the first centered at 2513.6 MHz as EARFCN 39826 and a second centered at 2533.4 MHz as EARFCN 40024.  Both of those are known.  The first already is in the list in the top post.  The second previously has been reported, though I have not gotten around to updating and adding it to the list.

Tried editing/formatting with some HTML to make it easier to understand.  Just passing along local market info to the general population.

Quick question - LTE and 1x800 can only be deployed if 1x800 is on channel 476, not 526, right?

We are hoping they deploy b26 3x3 in the 1x800 channel 526 area.

So what would the EARFCN of the 3x3 carrier be?

Aj, I have seen this on about 4 different sites near I-30 from Sulphur Springs, TX to Mt. Pleasant, TX.

I believe that is used in Flint Michigan too

It is just 5x5

So I'm at work where I usually do not get LTE unless the wind blows just right and noticed I had a faint LTE signal.

Mind you I'm in an iPhone 6s Plus so this could be a mistake in the field test app but 8321 denotes a second band 25 carrier right?

 

BTW this is in central Kentucky.

Yep that's a second carrier in the PCS B Block.

Nice.

 

What is curious is that I'm now getting a consistent LTE signal now with this carrier throughout my entire building where before I would have to get close to a window to get a LTE signal.

 

We do have cellular repeaters throughout the building so maybe that has something to do with it.
