Sprint 850 MHz is so Congested.


Recommended Posts

What app are you using that could show Bandwidth? Does it require root?

It must require root. I can't get the app to work on my phone.

The app is called network signal guru and it does require root permissions. The center frequency is the same for both the 5x5 and 3x3 carriers, so it seems to be measuring bandwidth in some way, shape or form. It makes me wonder why stock android engineering screens don't show LTE carrier bandwidth if the radio has the capability. Samsung devices have been the gold standard for BW measurement, and I've already seen a 3 MHz bandwidth LTE 800 carrier in the engineering screens.

The debug screen on Samsung devices shows bandwidth

Yep I reported 3x3 in MN way up north last summer.

Nope, still a pipe dream.  Only non cellular operations are permitted below 815 MHz x 860 MHz.  Moreover, some Sprint devices are not FCC tested/authorized in band class 10 below channel 476.

One thing I've wondered, SoutherLinc owns a few MHz below Sprints and below 815MHz.  Being a power company, I can see the public safety need, but still they operate a cellular network, has LTE, and apparently will be a Sprint roaming partner.

 

Did they get some type of special wavier?

Yes, but no. Although B26 covers 814-849 and 859-894, BC10 covers down to 806mhz on the uplink and 851mhz on the downlink. If Sprint were able to acquire some of the SMR spectrum below their current holdings, they could expand their B26 LTE carrier to a 10mhz FDD carrier (814-824 and 859-869) and push their 1x carrier into the spectrum below B26 but included in BC10.

BC10 is unavailable in Jefferson County due to Jeffco 911 DMR repeaters opperating at 850-864 MHz.

Not sure what point you're trying to make here? Also, how does posting the spectrum analyzer image prove anything is congested? 

My AT&T phone is compatible with B25 & B26 it roams on Sprint when I'm in a low coverage area and the network is very slow.

Oh…maybe that spectrum is free in other markets/areas though - after all SouthernLINC is operating an SMR LTE network sub 817/862 MHz…

Does it actually connect to the network? Sprint and, att don't have a roaming agreement.

Are you sure your phone isn't just scanning LTE bands? AT&T does not have any roaming agreements with Sprint.

    • I've now seen how things work in Kobe, Hiroshima, and Osaka, as well as some areas south of Osaka (e.g. Wakayama, Kinokawa), and tried three more SIMs. The two physical SIMs (different branding for each) both use IIJ, which provides a Japanese IP address/routing on NTT, aleit LTE-only, so latency is ~45ms to Tokyo. The catch with NTT is that it uses two frequency bands (B42/3500 MHz LTE, n79/4900 MHz NR) that you're not going to get on an Android sold in the US, and I'm guessing that B42 would be helpful speed-wise on that network, as it doesn't have B41. I also found one place that doesn't have cell service: a vending machine in the back of the Osaka Castle tower. Or, rather, the B8/18/19 signal is weak enough there to be unusable. Going back to 5G for a moment, I saw a fair amount of Softbank n257 in Hiroshima, as well as in some train stations between Osaka and Kobe. 4x100 MHz bandwidth, anchored by B1/3/8, with speeds sometimes exceeding 400 Mbps on the US Mobile roaming eSIM. Not quite the speeds I've seen on mmW in the States, but I've probably been on mmW for more time over the past few days than I have in the US over the past year, so I'll take it. My fastest speed test was actually on SoftBank n77 though, with 100 MHz of that plus 10x10 B8 hitting ~700 Mbps down and ~80 Mbps up with ~100ms latency...on the roaming eSIM...on the 4th floor of the hotel near Shin-Kobe station. Guessing B8 was a DAS or small cell based on signal levels, and the n77 might have been (or was just a less-used sector of the site serving the train station). I'm now 99% sure that all three providers are running DSS on band 28, and I've seen 10x10 on similar frequencies from both NTT and SoftBank IIRC, on both LTE and 5G. I also picked up one more eSIM: my1010, which is different from 1010/csl used by US Mobile's eSIM unfortunately, as it's LTE-only. On the bright side, it's cheap (10GB/7 days is like $11, and 20GB for the same period would be around $15), and can use both KDDI and SoftBank LTE. It also egresses from Taiwan (Chunghwa Telecom), though latency isn't really any better than the Singapore based eSIMs. Tomorrow will include the most rural part of our journey, so we'll see how networks hold up there, and from tomorrow night on we'll be in Tokyo, so any further reports after that will be Tokyo-centric.
    • I think the push for them is adding US Mobile as a MVNO with a priority data plan.  Ultimately, making people more aware of priority would allow them (and other carriers) to differentiate themselves from MVNOs like Consumer Cellular that advertise the same coverage. n77 has dramatically reduced the need for priority service at Verizon where the mere functioning of your phone was in jeopardy a couple of years ago if you had a low priority plan like Red Pocket. Only have heard of problems with T-Mobile in parts of Los Angeles. AT&T fell in between. All had issues at large concerts and festivals, or sporting events if your carrier has no on-site rights. Edit: Dishes native 5g network has different issues: not enough sites, limited bandwidth. Higher priority would help a few. Truth is they can push phones to AT&T or T-Mobile.
    • Tracfone AT&T sims went from QCI 8 to 9 as well a couple years ago. I'm pretty neutral towards AT&T's turbo feature here, the only bad taste left was for those who had unadvertised QCI 7 a couple months ago moved down to 8. In my eyes it would have been a lot better for AT&T to include turbo in those Premium/Elite plans for free to keep them at QCI 7, while also introducing this turbo add on option for any other plans or devices. As it stands now only a handful of plans can add it, and only if you're using a device on a random list of devices AT&T considers to be 5G smartphones.
    • My Red Pocket AT&T GSMA account was dropped to QCI 9 about a year ago.  Most recently 8 for the last few years prior.  Voice remains at 5.
