CDMA 800 Testing PRL


Recommended Posts

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 Download Center where it is hosted: http://s4gru.com/ind...-prl-21086xprl/

 

If you do end up ever actually connecting, turn off your 3G and run some speed tests on that 1xAdvanced 800 carrier. I would love to hear how it is operating speed wise since 1xA can be up to 3 times faster than 1xRTT, depending on how it is deployed.

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:

Robert and I have not been able to confirm any CDMA1X 800 SIDs beyond those that we have already announced. But those that we have announced have followed the pattern of PCS G block assigned SIDs (as laid out in the spreadsheet).

I just finished adding all Nextel SIDs for the entire U.S. Most regions search 476 then 526; the southeast will search 526 then 476. The native EV carriers are associated with the new CDMA 800 records everywhere. There is no roaming indicator and ESMR 1x is prioritized over PCS 1x.

Thanks! I have updated the file in the download center: http://s4gru.com/index.php?/files/file/18-cdma-800-testing-prl-21086xprl/

I'm using PRL 12117 (Network Vision Corporate/Network Vision Business PRL which has 3G roaming etc...) and I'm seeing channel 425 pop up under 1x Engineering in the debug menu which is in the 800Mhz range (CDMA AMPS) from my understanding. My femtocell seems to be configured to broadcast on that frequency.

I just did some more testing with the femtocell off and it's only using channels 325 and 350 while in call and while using data on sprints towers

While just coincidence, channel 425 happens to be a common CDMA1X carrier assignment for both Cellular 850 MHz and PCS 1900 MHz. To further the possibility for confusion, channel 425 also happens to be in the Cellular B block and the PCS B block. But CEL 0425 and PCS 0425 are two very different channel assignments separated by approximately 1 MHz.

 

In your case, your screenshots indicate band class 1 and that in turn indicates PCS 0425. For CDMA1X, band class 1 is PCS 1900 MHz, while band class 0 is Cellular 850 MHz.

 

Furthermore, you appear to be in Cleveland, where Sprint holds a PCS B3 block 10 MHz disaggregation from the old AT&TWS, and PCS 0425 is the first standard channel assignment in the PCS B3 block. Sprint also holds its original license, the PCS D block 10 MHz, which contains PCS 0325, 0350, and 0375, of which you have noted the first two channel assignments.

Thanks for elaborating on that, it really cleared things up. What I find odd is that they don't use 0425 on the towers in my area as far as I know anyways (I've never seen it pop up in the debugging menus). Quick question, is there any chance that you may know when Cleveland will be seeing any network vision upgrades?

We may be talking about Cleveland in the Sunday night chat at 9:30 PM Mountain time. ;)

Applied the PRL to my EVO 3D. I may sound like a noob for asking, but how will I know if I'm connected to 1x Advanced? Do I check the debug menu?

Yes. If you connect to one of the unofficial channels in PCS G Block or 800 SMR, then you are on 1xA. And if you ever connect, let us know here right away. No one has, yet.

 

The markets where testing is occuring right now include, Chicago, LA Metro, Boston, Austin, DFW, Kansas, Central Jersey, Washington DC and Baltimore. It is also assumed in Atlanta and Houston too.

 

However, the timing has to be just right. You have to be at the right tower at the right time.

I am afraid that the PCS G block enabled testing PRL is a non starter. In looking over FCC OET filings, I have not found a single Sprint branded handset that has been certified beyond the traditional PCS A-F block range. Maybe some do exist, but I have not found them. So, I surmise that only specially certified or waivered testing devices will be able access CDMA1X/EV-DO Network Vision trials in the PCS G block.

I was under the impression that the G Block was dedicated to LTE only, not 1x/DO

Deval, yes. However, Network Vision gear is being tested in G Block. 1xA and EVDO carriers get tested in G Block at every tower, including full drive testing. This is being done so as to not interfere with existing customers. Then, when testing is complete of NV gear at a tower or clusters of towers and it's ready to go live, they take the 1xA/EVDO carriers off G block frequencies and transition them to the appropriate A-F frequencies for commercial traffic. This is when the site is 3G live.

 

It is only after the 3G goes live do the NV OEM's start work on the LTE carrier and put it on G Block and start its testing. All Network Vision testing is done in G Block. But only LTE will be there permanently.

Good news. I have done some more digging, and the Samsung Conquer 4G (SPH-D600), Samsung Trender (SPH-M380), and Huawei Express (M650) explicitly support and have been certified for CDMA1X band class 14 (PCS A-G blocks).

Thanks for sifting through the data to find that out. Now, does anyone have these relatively obscure devices?

I see quite a few "bad ESN" Conquers listed on eBay. If I can pick one up for <$50, I would be willing to do that for testing purposes (though I would probably need to ship it off to one of you who can run QPST on your Windows OS).

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

Its not an app. Its your device Debug screen. You get to it by entering ##DEBUG# in your phone dialer. You will need to know your device MSL number to access it though.

Technically it is an app. :) you can even make a shortcut to it on your home screen with anycut.

 

I suppose if you want to be technical. :rolleyes: I just mean you ain't going to be downloading it from the market.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
    • 417.55 MB September security update just downloaded here for S24+ unlocked   Edit:  after Sept security update install, checked and found a 13MB GP System update as well.  Still showing August 1st there however.
