WiWavelength Posted January 31, 2014 Share Posted January 31, 2014 We are starting to encounter more and more distinct band 41 TD-LTE 2600 EARFCNs. Unfortunately, these pop up sporadically in various market threads and do not always come to my attention. Additionally, we are waiting on the first report of a band 25 LTE 1900 EARFCN outside of the PCS G block. At present -- and periodically updated -- the EARFCNs that have been documented are as follows: Band 25 LTE 1900: EARFCNs 8665/26665 [nationwide; PCS G block] EARFCNs 8315/26315 [Chicago MTA; former USCC PCS B block; second carrier] EARFCNs 8158/26158 [shentel; Washington-Baltimore MTA; PCS A block; second carrier] EARFCNs 8565/26565 [Columbus BTA; former Revol PCS C4 block; second carrier] EARFCNs 8465/26465 [Cleveland-Akron BTA; former Revol PCS F block; second carrier] EARFCNs 8415/26415 [Youngstown-Warren BTA; former Revol PCS E block; second carrier] EARFCNs 8321/26321 [Phoenix MTA; PCS B block; second carrier] EARFCNs 8308/26308 [Flint; Detroit MTA; PCS B block; second carrier] EARFCNs 8159/26159 [Lee's Summit; Kansas City MTA; PCS A block; second carrier] Band 26 LTE 800: EARFCNs 8763/26763 [nationwide; SMR X block]Band 41 TD-LTE 2600: EARFCN 39826 EARFCN 39858 EARFCN 39926 EARFCN 39956 EARFCN 39991 EARFCN 40056 EARFCN 40124 EARFCN 40254 [multiple markets; second carrier] EARFCN 40521 EARFCN 40719 EARFCN 40978 [multiple markets; first carrier] EARFCN 41078 EARFCN 41176 [multiple markets; was Kansas City BTA; Kauffman Stadium -- World Series; second carrier] EARFCN 41276 EARFCN 41374 Since there is strength in numbers, if any member encounters an undocumented EARFCN -- whether on an owned device or in someone else's engineering screenshot -- please report it in this thread. Just please do not report EARFCNs 65535 or 58978. Those are invalid values. Finally, remember that the S4GRU DL Center contains a spreadsheet that is periodically updated with all known WiMAX and TD-LTE carriers. http://s4gru.com/index.php?/files/file/29-clearwire-wimaxtd-lte-carrier-band-plan/ AJ 21 Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted January 31, 2014 Author Share Posted January 31, 2014 If you need a refresher on EARFCNs, see my engineering screen articles from last spring. http://s4gru.com/index.php?/blog/1/entry-345-whats-the-frequency-kenneth-interpreting-your-engineering-screen-part-one/ http://s4gru.com/index.php?/blog/1/entry-347-whats-the-frequency-kenneth-interpreting-your-engineering-screen-part-two/ AJ Quote Link to comment Share on other sites More sharing options...
S4GRU Posted January 31, 2014 Share Posted January 31, 2014 Great idea for a thread, AJ. Thanks for this. I'm looking forward to seeing other PCS entries, and possibly some varieties on the SMR with different size carriers in different positions.

S4GRU Posted February 1, 2014 Share Posted February 1, 2014 I was excited because I thought I found a new one (39991). And then I got here and found it already on this list. DOH! Robert Quote Link to comment Share on other sites More sharing options...

Destroyallcubes Posted February 6, 2014 Share Posted February 6, 2014 Not sure if these can count. I have been having some thing weird happen as of late. My phone connects just on the DL on LTE. It shows LTE Signal sometimes, sometimes not, either way the engineering screens are the same both ways. https://www.dropbox.com/s/fkqgr6j2w9ql0m0/Screenshot_2014-02-01-14-22-34.png https://www.dropbox.com/s/8gjfe4dtgtqzifw/Screenshot_2014-02-06-00-43-09.png The 8222 I know was just a scan, 8569 was on there for a bit.

WiWavelength Posted February 6, 2014 Author Share Posted February 6, 2014 The 8222 I know was just a scan, 8569 was on there for a bit. Did these occur in Tyler? Unfortunately, I do not think that either was an actual connection. And even if EARFCN 8569 was, it was not in spectrum that is licensed to Sprint in the Tyler BTA.

Hmm not sure what happened. But it might be a value to look for in other markets Quote Link to comment Share on other sites More sharing options...

Vince Posted May 30, 2014 Share Posted May 30, 2014 Aj, I was traveling through the southern suburbs of Chicago, when I noticed I was connected to band 41 with this frequency. I checked post #1 to see if it was on your "do not post, these are null values" list, and it wasn't. It never changed, and stayed even while using data, so I don't think it was null.

WiWavelength Posted May 30, 2014 Author Share Posted May 30, 2014 So it's an error on the phone's engineering screen? Hi Vince... Yes, the uplink EARFCN for TDD appears to be an error. Why it is even there, I cannot explain it. So, I should probably edit my instructions to indicate that you should report only the downlink EARFCN. If it is TDD, the downlink EARFCN is accurate. If it is FDD, I can calculate the uplink EARFCN from the reported downlink EARFCN. Also, I did not have a chance yet to thank you for supplying the official documentation of the secondary band 25 LTE 1900 carrier in Chicago. But I added the new EARFCNs shortly after your post and PM. The secondary band 25 LTE 1900 carrier is just as I expected at the high end of the former USCC license. That is wise spectrum management.

AJ Do you think Sprint might eventually sell its E block PCS license in Chicago? Quote Link to comment Share on other sites More sharing options...
WiWavelength Posted May 30, 2014 Author Share Posted May 30, 2014 Do you think Sprint might eventually sell its E block PCS license in Chicago? It is a possibility. To the PCS E block 10 MHz license, the adjacent license holders are VZW with the PCS B5 block 10 MHz disaggregation and AT&T with the PCS F block 10 MHz license. VZW holds no other PCS spectrum in Chicago, while AT&T also has the PCS A block 30 MHz license. So, VZW might be interested, while I think AT&T is already full up. On the other hand, Sprint might want to send its PCS D block 10 MHz license to AT&T in exchange for the PCS F block. That would give Sprint two separate 20 MHz contiguous swaths, while AT&T would end up with one 40 MHz contiguous segment. The third option is that Sprint keeps it all. And CDMA2000 operations are eventually shunted to just the PCS E block so that the adjacent combo of the PCS D block and PCS B3/B4 block 20 MHz disaggregation can run LTE at 15 MHz FDD. The band plan graphic that I created for the Sprint-USCC transaction article can be a helpful reference: AJ 2 Quote Link to comment Share on other sites More sharing options...

AJ I am assuming that eventually all of the USCC Spectrum would be used for LTE incrementally, and that as CDMA traffic declined they would simply sell off block E. Continuity is good though. Frankly, if Sprint needed money for low band spectrum, I could see them pairing down to about 30Mhz of PCS across the country (10Mhz for CDMA and a pair of 5x5 LTE channels), once they get a solid band 41 LTE network built up. With the new gear, the band 41 coverage is almost as good as the Band 25 coverage. Band 25 will mostly be for non-spark devices (old Sprint devices or roaming traffic).

Vince Posted June 11, 2014 Share Posted June 11, 2014 AJ, I know this is in your list, but I was wondering why there would be two different b41 channels in a market. I found this 40 minutes outside of Chicago last night. It strays from our usual 40056 Quote Link to comment Share on other sites More sharing options...

I found this 40 minutes outside of Chicago last night. It strays from our usual 40056 One carrier is deployed in EBS spectrum, the other in BRS spectrum. And "40 minutes outside of Chicago" is not necessarily still in the same licensed market -- especially for EBS. AJ Quote Link to comment Share on other sites More sharing options...
