Breaking Band: Tri-band LTE / eCSFB issues thread


Recommended Posts

I appreciate the effort, but I'm in Oklahoma, which you have listed as 'good' but I'm having issues with 3G/4G towers

The sheet is to display which markets the we KNOW as having issues. So anyone that is within their 14-day return period can return their device if needed. Other issues, ie the 3G/4G issue within incumbent markets which has been reported but we have no concrete data to go on. When I get mine I know that I will spend hours testing out multiple sites.

I do have a question about the Sprint internal memo though. Why does it list (in the acronyms portion) Ericsson as CSFB and ALU and SAM as eCSFB?

 

I think it's obvious, as with many other things Ericsson has the lesser of NV equipment that does only CSFB.  Same comparison where Samsung is doing 1xA on PCS and 800SMR and Ericsson is still doing 1x on PCS without 800SMR now.  I would assume these are just software updates to get them up to par though since things are supposed to be SDR.

Anyone started plotting out where people are having issues and where people aren't?  Seems like time better spent instead of guessing off some memo which obviously isn't 100% correct.

It appears that in addition to the incumbent/non-incumbent issue, sites that have not had upgraded software for eCSFB are also giving issues if they are 3G/4G. This could possibly explain issues in Missouri and Oklahoma that we have been seeing.

I think from what we have received info is dead on in non-incumbents. Incumbents are having problems with 3G/4G sites. We need more data.

Actually, you are Shentel. It appears no Tri-Band devices are playing nice with the entire Shentel network yet.

Thanks I was curious, didn't see anything mentioned about them. Guess its back to the HTC One for me!

We're not sure why things aren't working there yet. It's possible that the Shentel towers haven't received the proper software update yet. Very strange.

I can tell you both Green (3G/800/4G), and Yellow (3G/4G) sites are a problem. I tried traveling to a yellow today, just thought maybe it would pick up LTE, no dice :(    only ePHRD connection.

Anyone within a market where GCI(HEX SCID's) are being collected, please post any LTE Engineering/SignalCheck Screens so we can check our maps/sheets to see what site you are connecting to.

So in markets where people are having problems connecting to LTE (for me it's Lincoln/Omaha, NE), do users also have a problem connecting to 1X800 as well??   are these 2 problems directly connected to each other?

 

with my GS3 i would pick up 1X800 at home but now it does not see it no matter what??? :o

Are you running a custom PRL that has 1x800 has a higher priority?

as you have probably seen in the nebraska/west iowa spreadsheet thread, ive had no problem connecting to 1x 800 using the stock prl

 

hmm very odd.  does the stock PRL prioritize 1XRTT?  know how to flash custom PRL's?

i think they are set at same priority but it scans the 1x 800 first after a reboot and if not found, it wont scan for it until you need it, as far as flashing a custom prl, this May work, but im not sure

Robert just posted an article detailing the eCSFB issue with tri-band devices.

 

Read the whole article here.

 

I will also add the link to the OP. 

 

If you find an issue that cannot be explained by the information in the article, please continue to post. There may be more to work out.

After reading Robert's outstanding article on the fallback switch issue, I wish there would be a way for us to find out when each of our markets would be fixed!

 

It would be really nice to have some sort of timeline as to when the upgrades will take place and our phones will start receiving LTE.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). The do have a reserve level. It is seen as great for new technologies which I presume is IOT or 5g slices.  They did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, RVs in Walmart parking lots where mobile needs all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71. 93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline in June for 850Mhz of mmWave in most of Ohio iirc. No reported sightings.
    • T-Mobile Delivers Industry-Leading Customer, Service Revenue and Profitability Growth in Q1 2024, and Raises 2024 Guidance https://www.t-mobile.com/news/business/t-mobile-q1-2024-earnings — — — — — I find it funny that when they talk about their spectrum layers they're saying n71, n25, and n41. They're completely avoiding talking about mmWave.
    • Was true in my market. Likely means a higher percentage of 5g phones in your market.
