Two Sites supposedly live with CDMA 800 in Rural Chicago Market

ATTENTION S4GRU MEMBERS! WE HAVE A LIVE ONE...err, two!

 

I was going through my latest list of live NV sites, and I came across two sites labeled with CDMA 800. All the NV completed sites to date have been labeled CDMA 1900 or LTE 1900. Does this mean that the 1xAdvanced carrier is active on Channel 476 on these two sites? It looks like it!

 

If you are in the Chicago area, have a 800 SMR capable device and have the skills to install our 800 CDMA PRL, then please drive out to the Rochelle/De Kalb area and try to connect to these 800MHz CDMA sites on Channel 476. This is some crazy exciting stuff for the wireless nerd!

 

If you are going to give it a try, let me know before you head out there. The suspense is killing me. See the map of the site locations in question below.

I live in Yorkville and my dad lives in Waterman. I can test but Im not sure what device is required. I have a Epic Touch and OG Epic. I have installed custom prl's on the touch a few times, but Im unsure It either of these devices are able to get on 800. Let me know If I can and I will post my results when I can get out by Waterman. Also in Yorkville we have been having many dropped calls, duplicate/late text, time changing to a hour ahead. Do you know what is going on in my area this last month? I know they have lost quite a few costumers because of this. Is you list of live NV sites public? If so where can I view this at?

Thought someone in LA already connected his EVO3d to an 800 1xa carrier?

 

We did get a report. Was likely testing, since these two sites are the first ones to show live in the Sprint system.

 

Interesting, i thought they couldn't deploy 800 if iDEN was active, and that is definitely in iDEN area.

 

Sort of. They cannot deploy 800 CDMA on Channel 476 until enough iDEN channels have been cleared out of the way for it to be used. It appears that Sprint is removing some iDEN carriers this year, just enough to deploy 800 CDMA on Channel 476 in most markets. This will substantially improve voice coverage in advance of full iDEN decommissioning.

 

Im in Maryland and I connected to a nv site and using the test prl I was on channel 476. is this 800 mhz?

 

Please post a screen shot of your Debug screen the next time you connect. Would love to see some verification of 800 CDMA live in your area. Thanks!

Will the Galaxy Nexus be able to use 800 CDMA?

 

Yes. Once the PRL is updated in the future to run on it. Or you download ours.

If there any plan that lists where this will be done, or do we just have to wait for them to complete the sites?

I'm in waiting mode. I have not seen any plans of this occurring, only evidence of it.

So it should be available in the next 12 months, or so?

 

Sooner. I believe they will push a PRL that will run on 800 CDMA in the near future.

##DEBUG# in your phone dialer. Does not work with some custom ROMs, like anything from Cyanogen. Most devices, you will need your MSL #.

I have a screen shot.

I have a screen shot.

 

 

Thanks for the screenshot. Of note, it is coming up SID 22429, which is allocated to Idaho/Utah/Western Wyoming. It should be 22435, according to this. It looks like Sprint has made some modifications to the SID list. Or maybe there is an error in the programming of the carrier? Cool stuff.

SO 33 is 1xRTT-- your phone must not support RC11/RC8 (1xAdvanced). At least it should work fine. I'm a little disappointed with the -84 dBm signal... you're either a good 2 miles from that tower or there's alot of downtilt (as I would expect in a dense urban environment). In Maryland, your SID should be 22435. Locking onto the SID you have, I would expect your 3G (EVDO) to be lost since I'm sure the ACQ records don't match! I can remod the PRL to use the 22429 SID in your area with its native EV carriers. 22429 should be Salt Lake City market.

I would not worry about that -84 dBm RSSI. But look at that -3.0 dB Ec/Io. That is stellar -- no doubt, a completely unloaded carrier. Even with a strong signal, typical Ec/Io in a moderately loaded cell is roughly -7 dB.

    • 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). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile 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, FWA Mobile in RVs in Walmart parking lots working where mobile phones need 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, 90% 5g.  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 also with its shorter range.  
    • 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 June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No specific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.

They're completely avoiding talking about mmWave.
