Tengen31 Posted May 22, 2019 Share Posted May 22, 2019 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?Sent from my SM-G965U1 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Seems like I hit the max on 64 QAM. I am on S10 Plus, will I see 256 QAM? Quote Link to comment Share on other sites More sharing options...

Brad The Beast Posted September 4, 2019 Share Posted September 4, 2019 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. Quote Link to comment Share on other sites More sharing options...

Sprint upload speeds would be better if they did 25+41+41+41 CA and not just 41+41+41Sent from my SM-G965U1 using Tapatalk Quote Link to comment Share on other sites More sharing options...

I did see 31Mbps up on what must’ve been that newly widened 15x15 band 25. It was wonderful! 1 Quote Link to comment Share on other sites More sharing options...

insurance Posted December 9, 2019 Share Posted December 9, 2019 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. Sent from my SM-G965U using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

bookertdub Posted April 11, 2020 Share Posted April 11, 2020 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).Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Sent from my Pixel 4 XL using TapatalkI 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.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

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.Sent from my Pixel 4 XL using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
bookertdub Posted April 20, 2020 Share Posted April 20, 2020 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.Sent from my iPhone using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
