S4GRU Member 4ringsnbr created a custom PRL for those of you PRL masters out there who want to search out the new CDMA 800 carriers in Network Vision markets.   Here is the link to the S4GRU Downloa

For the remaining markets, it is a relatively safe bet to add a band class 10 ACQ index entry with channels 476 and 526 to these SIDs:   https://docs.google.com/spreadsheet/ccc?key=0ArY31Mr219-ydEZu

Looking at this ESMR link in California and a new one in Maryland, it appears that both are using the Utah SID (22429). Maybe they haven't yet configured the channels properly or just don't know how

I'll upload it later. I'll just leave this here for the moment: Band# CDMA Cellular, CH# 476 and SID# 22429.

Rai, you did find me a protection site once. Did you come through with another first discovery???

 

I'm waiting with baited breath!!!! :azn:

I'm glad to know the PRL works properly on phones equipped for Band Class 10-- though the band should be reported as "CDMA Cellular 2nd", but who knows how the firmware for the radio is configured! The PRL scan will ALWAYS prioritize the ESMR 1x carrier over your native PCS 1x carrier, but the EVDO (3G) association will always use your native PCS carriers. Please note that use of this PRL will likely cause increased battery draw since the phone will periodically scan for ESMR 1x carriers as a preferred link even if you have a great signal on your PCS 1x carrier. If you'd like to have any functionality changed, please let me know... I can disable EVDO upon ESMR 1x acquisition if you want that. I made it this way so that you can still use your phone normally and let it scan for ESMR carriers in the background.

What app is this that tells you the channel that you are using?

 

Band Class 1 is PCS (1900 MHz)... every band class has its own channel numbering scheme.

 

FYI..

For band class 1 (PCS)-- A block starts at 1850 MHz with channel 0... the spacing is 50 kHz per channel and the downlink frequency is 80 MHz higher than the uplink. The first usable CDMA channel is 25, then 50, 75, etc.

For band class 10 (ESMR) -- Channel 0 is 806 MHz... every channel is 25 kHz wide and the downlink is 45 MHz higher than the uplink. The first usable channel (to Sprint handsets as FCC approved) is centered at 817.9 MHz, which is 476, then 526, and 576 and 626. 676 would only be usable with allowances made by the area's cellular A side (band class 0) carrier.

I would go into band class 0 (cellular), but I've had too much wine-- there are two different channel numbering schemes and CDMA carriers in this band are 1.23 MHz wide rather than 1.25 MHz in all other band classes... you'll only see this band class when roaming on Verizon or Cellular South, so don't worry about it.

You're on the FAR edge of that cell-- you must be 5 miles from that tower! Signal is weak, but you're on ESMR. Service Option 0 may mean you're not actually in service... The big question is whether your forward link is set to RC-11, which would indicate 1xAdvanced versus 1xRTT, which would be RC-3.

Channel 476? That is an ESMR band and it's in Riverside? Wow. Sprint is moving fast in some areas!

Well I was in the freeway when I screenshot it (wasn't driving though). The weak signal does explain why it kept changing from CDMA cellular to CDMA PCS.

yeah-- the PRL should jump to the standard PCS scan if it loses the ESMR signal (goes below -113 dBm)... but it will ALWAYS search for the ESMR carrier first and constantly-- even if it has a good PCS carrier signal. You should be seeing significantly lower battery life-- SORRY!

That's ok. I can switch back to my old prl anytime. Forgot to mention that I saw some engineers working on a tower near the freeway in downtown L.A. I don't know if it was a Sprint tower though.

Actually, this was from downtown L.A. Riverside's still on 1xRTT (for now).

Downtown LA? Even more surprising.

Thanks for sharing

Robert, have you been eating bait? Eww! And, judging from another thread, eating that bait has not only given you bad breath but also grown hair on your brain.

It would have to be in LA. There is active deployment going on Downtown, the 110 Corridor, Hollywood and San Fernando. There is no activity in the Riverside market yet.

Was it determined that the Evo cannot lock to the G block? Which block would channel 725, band class 1, band # CDMA PCS be?

Are you talking about the EVO 4G or EVO 3D?

PCS 0725 is the first full CDMA1X channel assignment in the PCS D block, which is one of two PCS A-F licenses (the PCS E block is the other) that Sprint holds in Chicago.

 

When I was last in Chicago a few months ago, PCS 0325 and 0725 were the two EV-DO carriers that I encountered, while PCS 0350, 0375, and 0775 were the three 1X carriers that I spotted. So, I suspect that your PCS 0725 is an EV-DO carrier.

      Someone told me a couple years ago, that there were problems getting certain modems to aggregate overlapping spectrum even if the overlapping parts were actually blanked. So I think there might be firmware issues that need to be resolved first, which T-Mobile might not consider worth the effort for 4MHz at this time.

      Tbh not that surprising. Every ISP seems to want to have an MVNO to pitch to their customers to make them stickier and maybe make some money in the process. And unlike USCC the MVNO should be able to cover TDS's entire wireline area, with infrastructure costs that are borne by someone else. Entertaining, yes. Surprising, not really...particularly when competing against Comcast or Spectrum, or even eventually T-Mobile fixed + mobile. This also strengthens my bet that they'll rebrand all their fixed wireless stuff as TDS, as that runs on spectrum they're keeping for now.

      No? RCS on Google messages works great for me, messages between anyone with RCS enabled go through with no problems. Don't remember the last time I had an issue. I only have issues with people on iPhones on different carriers from T-Mobile.

      Has anyone experienced a ridiculous amount of difficulty with Google messages with RCS enabled?  It has been a train wreck for me for the past year so I now use WhatsApp.  That works very well for all of us.... Android and iOS.

      Probably not worth the fiddling given that that's a few percent of the band. Also, if they really wanted to push my assumption is there are still guard bands in play for the n41 carriers so they could fit two "100 MHz" carriers into 194 MHz anyway. Looks like minimum guard band is less than 1 MHz and a 100 MHz channel is only 273 30 KHz resource blocks, which is a bit over 80 MHz total, so if they really wanted to pull another 5% or so capacity out they could.
