Network Vision/LTE - San Diego Market

64 QAM 2x2 MIMO 20 MHz Config 2
3 x 112.5 = ~ 337.5 mbps
256 QAM 4x4 MIMO 20 MHz Config 2
3 x ( 112.5 x 1.33 ) ( 2 ) = 3 x ( 150 ) ( 2) = 3 x 300 = ~ 900 mbps aka gigabit class LTE. 

Hey Tim how many cell sites actually have 256 qam on it?

Seems like I hit the max on 64 QAM. I am on S10 Plus, will I see 256 QAM?

Yes if the SINR on the sector is very clean and your device and the eNB connects with 256 QAM.

This is the best speed test that I have had in San Diego

I was pleasantly surprised with Sprint’s performance in my recent short trip to San Diego. Inside the airport is still terrible to ok but outside the airport and around Pacific Beach was very good. I was extremely disappointed with Verizons service in Pacific Beach. Severe congestion led to the inability to break 2Mbps down.

Here is a summary of my tests from this recent trip:

Sprint Average DL: 57.75Mbps

Verizon Average DL: 42.66Mbps

Sprint Average UL: 8.07Mbps

Verizon Average UL: 12.57Mbps

 

Verizon’s average speeds were bolstered by excellent performance at the airport. Sprint’s fastest download speed was 149Mbps while out and about in Pacific Beach. Verizon’s fastest download was 123Mbps inside the airport at gate 36. This isn’t exactly scientific as these were the averages of only 7 tests so take it as you will.

That area should have tons of B41 and I think 10x10+5x5 on B25. Sprint upload speeds would be better if they did 25+41+41+41 CA and not just 41+41+41

The upload speeds weren’t terrible. They must’ve had upload CA enabled. I did see 31Mbps up on what must’ve been that newly widened 15x15 band 25. It was wonderful!

San Diego has 15x15 L1900.

Thats right I think Sprint has contiguous spectrum there. 20x20 which would allow for that 15x15

Yep I forgot about that. Is there a 2nd carrier on top of that? Spectrum Omega shows that Sprint has the A,C and G block there. I know c and G are accurate

Nope. Just the 15x15 C4+C5+G carrier right now. 

Sprint doesn't own any PCS A block spectrum in San Diego. The A block is wholly owned by AT&T.

Though so. TMobile has 15x15 B block.. att it's likely 20x20 and VZW IDK

AT&T: 20x20 L1900 (PCS A+D, EARFCN 700)

Verizon: 10x10 L1900 (PCS E+F, EARFCN 1000)

T-Mobile: 10x10 L1900 (PCS B, EARFCN 850), 5x5 UMTS/HSPA

Sprint: 15x15 L1900 (PCS C+G, EARFCN 8615), 5x5 1x/EVDO

Did some tests today since I haven't in awhile. Was waiting for my kid on 4th st in El Cajon, between granite hills HS and Montgomery Middle. Pleasently surprised. I wanted to hit 200 so bad, but figured I'd keep testing as a quasi stress test when the brats at the middle school is out at 2:30. I believe the antenna is at shadow mountain church, which is east and across the High School.

25+41 aggregation reported online in San Diego! 

[bookertdub]

Got this in Carlsbad near the intersection of El Camino Real and Aviara Pkwy/Alga Rd on Band 41. This is easily the fastest download speed I've ever experienced on Sprint's network (I don't know this had to do with T-mobile since this was after the merger closed).

It's possible that T-mobile is upgrading the backhaul finally. A lot of Sprint sites have backhaul capped around 150 Mbps to save money.

I didn't know Sprint had capped their backhaul to 150 Mbps download speed. That said at least for a smartphone, that's more than enough. But I won't say no what's nearly twice the download speed.

It's not all sites. But a lot of sites have that as the backhaul.

For a single device you're right, that's more than enough. But this is the bandwidth that's shared between all devices on the tower. I'm hoping on sites that are heavily utilized, that they have more backhaul. But from my own experience on a few sites that crawl during the day (under 1 Mbps during peak usage on b41), my suspicion is no.

Looks like T-mobile has removed the 5 Mbps throttle on roaming. It showed up as native Sprint coverage inside the only Ralphs grocery store inside the City of Carlsbad. When I did the field test on my iPhone 7+ it showed up as Band 4. Previously I when I would walk inside this particular grocery store it would go down to 3G.

Any 5G updates in the San Diego market?
