    "1xRTT" on Signal Check is 1900 voice/text - if you're on 800 voice/text, Signal Check shows "1x800". People in this forum far more knowledgeable than I am have suggested that B26 usability will fall somewhere between 1900 LTE and 800 voice: The RSRP (or RSSI or whatever) will be similar to 800, but due to the fragility of the LTE protocol itself, 800 LTE will not usable quite as far away from the antennas or as deep into structures as 800 voice.

    See my post 3 up from yours, and also one I just did in the Milwaukee thread. Chicago is in fact pretty Sparky.

    Actually, much of the Chicago area has 2500/2600 Band 41 LTE. I've personally found near-continuous coverage at least along I-90 from the exurbs all the way to (but not including) the Loop, and on I-290 from Woodfield to the Loop.

    2 weeks ago: Northern Illinois, 22 below zero actual, minus 45 wind chill. Snow. 1 week ago: L.A. & Orange County: High 80's with earthquakes, drought, and wildfire. This week: Northern Illinois, 10 below zero actual, minus 25 wind chill. More snow. Next week: Northern Illinois, 20 below zero actual, minus 40's wind chill. Oh, and maybe another foot of snow. A: Why do I live in Northern Illinois???? B: Is it better to have a week of summer between weeks in the Arctic, or does it just make you feel worse having to come back? (But my LTE was really good in California!) (And the earthquake was really entertaining!)

    3 of the 6 Sprint sites nearest the Amtrak station have LTE, 3 don't. However, the spacing is such that decent LTE reception may not be available until 800 MHz LTE fires up later this year

    At this time, there is no indication that Sprint has decommissioned any Clear sites. The Premier Sponsor maps show essentially all of the Clear sites as scheduled for 2500 LTE, at least in those markets where any schedule is shown. Specifically in Chicagoland, I have charted a bunch of Clear sites between Elgin and the Loop, some of which seem to be stand-alone and some co-located, but all of which are carryovers from Wimax. Again, The Band 41 maps for Chicagoland show all of the local Wimax sites as being scheduled for upgrade to LTE. [Edit: And it's Clear that cdk types faster than I do. ]
  8. tommym65
    Not exactly. Green pins (now including almost all of Chicagoland) mean that the site is broadcasting 800 voice, 1900 CDMA voice and data, and 1900 LTE. Most likely, you will be on 800 voice if your handset supports it, but the network can put you on 1900 voice anytime it wants.

    DEFINITELY not A) .

    FWIW, I have spent all week kicking around LA, the Fairplex, and Santa Ana, and have been getting good Band 25 LTE almost everywhere I've been, including solid 28 Mbps download on my hotspot inside Bldg 7 at the Fairplex. No Band 41 that I have seen, but I am currently on 800 voice at LAX. Much better connections than the last time I was here a few months ago. Oh, and thanks for the Disneyesque earthquake (lots of shaking but virtually no damage). Very nice of you to keep us visitors entertained. Now back to the tundra.

    Also, Sprint has the spectrum to add one or maybe two 1900 LTE 5x5 carriers in certain markets, and multiple 20 MHz 2500 LTE carriers in many markets.
  12. tommym65
    Does this help?

    I also have screenshots with 311-870 in Minneapolis.
  14. tommym65
    If you were on Band 41 LTE, you were on old (slow) Clearwire backhaul, and 13 Mb speeds are pretty good. If you were on Band 25, 13 Mb is excellent in most parts of Chicago due to heavy traffic. When Sprint starts installing B41 on sites with NV backhaul, 60-plus Mb should be attainable as an optimum, but keep in mind that traffic and distance always reduce throughput.

    The St. Louis 2600/Band 41 thread has a large number of Band 41 sites identified, and somewhere back about 2 or 3 months ago, I posted a formula for converting the Cell ID from a Zing hotspot to the Site ID. The Cell ID is reported in decimal, the Site ID is hexadecimal, and there is an offset representing the "market". The method worked for most St. Louis sites, but there seemed to be 2 or 3 random renegade sites. I have done similar conversions for Robert's initial Denver sighting, for Minneapolis, and on a somewhat larger scale in Chicago (posting in the appropriate threads as I went), but I don't remember the links off the top of my head. I realize that this is off-topic (sorry, Mike), but if anyone is interested, I could post the ID method I found -- Probably best in one of the 2600 threads. When the tri-band phones finally start routinely recognizing B41 and reporting it through Signal Check, we should be able to figure out coverages very comprehensively.
  16. tommym65
    Do you have a link?
  17. tommym65
    In my OP, I explained that I was using a hotspot to see Band 41 while driving in to the city.
  18. tommym65
    Probably because of time of day. Both my recent trips were from late afternoon until late evening, and both were technically outside the Loop (1 north, 1 south). I should also have made it clearer that I didn't get any band 41 east of 90/94. My speed and SNR observations were Band 25 on my GS3.
  19. tommym65
    At this time, Sprint can't do 10x10 on 1900 PCS, because many devices (such as all Samsungs) are engineered only for 5x5. Sprint can't do 10x10 on 800 SMR because it lacks sufficient spectrum.

    Everyone's fingers have been too frozen to type. Seriously, I go downtown only occasionally, and haven't been in the city since just before New Year. Just before Christmas, I was south of the Loop (in a shopping center near Roosevelt & Wells) and got good LTE signal strength, good speeds, and good SNR values, even inside most of the stores. Just before New Year's, I was at State St. & the River, and got similar results. On both trips, I monitored connections all the way in from about Elgin with my Zing hotspot, and was getting Band 41 LTE almost all the way, with very good Band 25 where there was no Band 41. (I was rather surprised at how comprehensive the Band 41 coverage was). Where I wanted data (including inside the House of Blues), I had no connection or speed problems. Importantly, both trips were in the late afternoon/evening, so I realize that they may not be representative of weekdays.
  21. tommym65
    Although additional carriers on Band 25 will also make Sprint more competitive, where they can scrape up the bandwidth to do it.
  22. tommym65
    Mike, Please consider adding the release date to the "About SignalCheck" screen. At my advanced age, I cannot remember the release numbers, but on my good days can still remember dates. Thanks and Merry Christmas.

    From a reliable source (my daughter): LTE on a GS3, this afternoon, inside a brick building 1/2 block south of the Downer Theater: RSRP -92, 3.37 Mbps down, 6.80 up, 114 ms ping. There is a site behind the theater, but it is not shown as LTE accepted, so this one is likely about 1/2 mile down Prospect. Merry Christmas from Sprint!!
  24. tommym65
    Good grief, that one hit so hard it knocked all the letters backward!
  25. tommym65
    I do. The pain killers are making me too woozy to drive. Maybe I will operate some heavy machinery . . I know, how about a train!
