Network Vision/LTE - San Diego Market

Was on interstate 5/805 split towards 52, found multiple 2nd carrier B25?  Can someone confirm if the GCI is in fact 2nd carriers?  If it is, this would be the first 2nd carrier B25 spotted in San Diego.

 

 

 

 

 

 

Standard ALU added carrier (B25 or 41) is #9, #A, #B.

 

EARFCN 26109 / 8109 corresponds to carrier center frequency at 1936.9 / 1856.9.

  

In San Diego County, Sprint is licensed the entire PCS A block 30 MHz from 1850-1865 / 1930-1945 MHz.

 

1936.9 would place 5 MHz FDD-LTE carrier right in the middle from 1934.4 -1939.4 MHz. 

 

So yes. You found Sprints 2nd B25 carrier in San Diego.

 

We received news that numerous major Alcatel-Lucent markets were farming PCS over the summer so with you finding it I expect rest of Southern California and areas like New York City to have it soon as well.

Locked onto B41 in Oceanside (O'side Harbor) passing by heading back south from San Clemente earlier this evening on the 5. I happened to take a quick glance, and noticed GCI ended with "A" on SignalCheck. Was that 2nd carrier?

 

Couldn't get a screenshot to verify.

Most of B41 in San Diego has second carrier and CA enabled.

Good to know! I never knew that.

How do you identify what carriers are being used?

SignalCheck or engineering screens. For CA engineering screens.

Temple Heights site in Oceanside, is now live with B41

I've been noticing a couple of spots in Oceanside that has been on 1x for the past week. One of these locations is a 3 mile or so stretch on the backside of Douglas Dr where I live. Yes there is a LTE GMO site on each end of this stretch. In between has always been a dead zone for not having Sprint service as long as I can remember over the years. There is also a couple of large neighborhoods in that area. I did notice for the first time, is a new site setup that just went up standing in between the 2 other sites. Below is a pic. Is this Sprint?

Nope. Those antennas and tower mounted amplifier points towards the other three carriers.

Gotcha. Thanks for confirming.

I got home from work not long ago, pulled into my driveway and heard my roaming alert. I looked at Signal Check, and noticed I'm on Sprint LTE, and Verizon 1x. Weird. Has anyone else seen this before on your phone?

Not possible on a Triband phone. But is on a Uniband phone and happened all the time. You can only be on 1x or LTE at any one time on a Triband device. It is either a Android reporting error or SCP error.

 

It looks like your device is actually just on 1x roaming, and the LTE data is stale.

Confirming border has CA.

 

[Marv1]

B25 CA in Cardiff?

No. It's just the second Band 25 carrier that Sprint has fired up as they have refarmed the spectrum from CDMA.

Here's another in that stage I found this afternoon in Oceanside just off the 5/Oceanside Blvd, about a half mile, to a mile away from a newly live B41site that has CA.

 

 

[Marv1]

This site in Oceanside has been live for about a week and a half. I stopped by, and it has CA. Can somone explain to me what's the difference to "A" and "B" when it comes to CA. I couldn't find anything on here explaining the diffrence, unless I overlooked it. I also took screenshots of this site being both A and B CA while driving around in the parking lot, and captured a screenshot of it without CA along with speedtests for each. Verizon also share this site.

My fault, but this is the location of the B41 site above.

It does not appear that Carrier Aggregation is live on this site. Notice that there is no information populating the SCC fields on your engineering screen. That means you do not have a secondary carrier connected on your device. You are simply connecting to the second B41 carrier, but it is not being aggregated. 

 

In regards to the "A" and "B", that just denoting your sector. Just like 01, 02, 03 showed you the alpha, beta and gamma sectors on B25, 31, 32, and 33 show the same respective sectors on B41. 39, 3A, 3B show the same sectors, just on the second carrier.

[Marv1]

Thanks for explaining that. This morning I've been noticing way more B25 carrier in North County this morning. Is this occuring at B41 sites?

[tmiw]

I just came back from a business trip to the Bay Area and I was amazed at how well Sprint actually performs up there. I was on LTE (B41 most of the time, even) the vast majority of the time. The only issue I has was inside one particular conference room at the office I was visiting, where my iPhone dropped to 1x on SMR; the phone seemed to be on B26 the rest of the time in that building.

 

Too bad there's still hoops to jump through before San Diego County gets B26.   Even though I get B41 at work if I'm near the outer walls, I still drop back to 3G if I go deep inside the building.

B25 twice. Oceanside near Sizzler

Any of you experiencing a lot of 3G service at LTE sites? I've been noticing a lot of this all throughout North County all week.

Nope. If anything, I think I was getting LTE more often than I remember getting.
