Okay, so I know PRLs tell the device which Sprint tower/site to connect to, but is this the case with LTE, too? In other words, would I be able to force LTE 800 over LTE PCS with a PRL? I'm wanting to force it once a triband device comes out so I can tell when it comes live in my area. I have great LTE 1900 signal so I'm afraid my device won't connect to it if 1900 is sufficient. Also - if PRL controls LTE connectivity, then why the sim cards? For authentication purposes?

Why would you want or need to connect to 800 if you have great 1900? You would just be clogging up the 800 network for people that need it.

The PRL does not tell the device which site to connect to. I would suggest reading both of the PRL articles on The Wall here at S4GRU.  The only thing in the PRL that affects LTE is one setting per Geo that says to scan for LTE or not.  It doesn't even tell it where to scan for LTE.

It'd be more for just an observation.  I'd like to know when it came live rather than use it, itself.  Kind of similar to how I check 3G speeds on my local tower, even though I have LTE on it.

 

Knowledge is power!

Thanks for this explanation.  Pretty much sums up everything.

      The DAS at LGA Terminal B actually has n41 at 100+20, but if you are deprioritized, good luck on the busy days, as all the bands are congested, even B41 and n41, with data being worse than 128kbps international roaming. It has SA active for n41 as well. The L train tunnel is actually 80+20 for n41, with SA n41 active. Speeds aren't anything compared to Philadelphia's DAS system that has n41 though. The gig+ upgrades are expanding, as eNBs 894588 (Sprint convert site) and 55987 can both pass 1 Gbps now. Clocked nearly 1.3Gbps on eNB 55987 today.

      Yup 80MHz C-band + 40MHz DoD for a total of 120MHz. They should be pretty well setup post-clearance. — — — — — Famous Verizon site on Atlantic referenced in this reddit post got moved to the top of the building next door. — — — — — Also looks like I mapped a T-Mobile oDAS node eNB 347812 in Brooklyn Heights. Streetview shows it as one of the CC nodes with no antenna on top as of May 2022 but this specific eNB was first mapped this month. I didn't notice that I mapped it until I got home but the range on it is significantly greater than the normal "antenna-less" nodes T-Mobile deploys. I'm wondering if it got upgraded to the new 5G oDAS design but I won't be able to check it out until next weekend.

      I didn't know they had access to 80 MHz of c-band that does change some things then once that's online

      While I've been loath to update my Samsung devices past the May 2022 update to keep the Band Selection tool, I note that it looks like Android 14 is going to add Timing Advance for NR to the API.  (Was looking today as I have another Verizon A42 5G now that I'm going to unlock for T-Mobile, and wanted to figure out if I should let it update or not.)  Since I can technically make band changes from *#73#, on the A42 5Gs, I can probably live without the Band Selection tool if a later Android version adds something useful like TA values. I assume SCP will be updated to support that once it becomes publicly available.  The real question is whether or not the phones will support it.  My S21FE and A42 5G devices do on LTE, but I know the S22 and the A32 5G do not support it even on LTE, providing just zero in that field. - Trip
