    Yikes. That shouldn’t be happening at all. I’ll check on it tomorrow and see if it was sent out. The network ticket will totally help.

    For "s and g's" I set my J3 Star to connect to 3G UMTS only.

    Tmobile still allows ATT domestic roaming in this area (N WI) even with band 71 deployed.

    Connected to ATT 3G UMTS band 5 and performed a speed test.

    Speed was throttled to "2G" ~120k up/down, BUT ping was a very respectable 95ms!

    Tmobile has to get this band 71 ping fixed!

    That's made up BS by people who want to get you off the phone. I hit better than 60Mbps on B71 10MHz here in SoCal with around 22ms ping.

    What's ironic in some places... I get better throughput on a further away B71 site than I do on closer B4/2/12. In Ventura, I was getting 4Mbps on local site, but +20 on further away B71 only (forced B71)Name:  1567888041580.jpeg

    Probably cause not many near by are on the band or have a device that can access it in the area. Or. Network config forcing ppl to the other bands unless signal is very weak.

    I actually was able to get B2 15MHz + B4 20Mhz from the same site as B71 alone... Sad part was it was 5x more throughput on B71 alone. Signal wasnt bad just I suspect not running CA with B71... Possibly not ready for prime time.Name:  Capture%2B_2019-09-07-13-35-00.jpeg

    How are the ping times now in the areas? Got a meeting with executive later today to escalate further. Phone and hotspot?

    Well, there'll be 2 reasons for that.

    1) B71 is probably a 5 or 10mhz channel, which would of course limit speeds compared to 35mhz of CA spectrum.

    2) I would expect in areas with B4, B2, etc., B12 and B71 would be used just for devices near the edge of service. So, that 5mhz channel that "could" be getting 50mbps or more could be getting 5-10mbps with nothing but distant devices on it.

    My KeyOne (2 channel CA) on Verizon Wireless, I usually see just that -- B4+B13 carrier aggregation (B13 is a 10mhz 700mhz channel). The traffic goes over B4 entirely if the B4 signal is good, and kind of shifts more and more data traffic over to B13 as the B4 signal drops off, finally shifting to B13-only if it loses the B4 signal.

    It seems T-Mobile network is doing the opposite in a way. It waits until b4 is completely weak or gone before it even tries b12/71. And even so. It doesn’t balance well. It’s kinda odd. Verizon sounds smooth.

    That doesn't sound right... it means no carrier aggregation. When I was on I-75 in June, I had B71+ B4 and no issues. What does happen in SOME places in rural northern MI, however, is that they did build some sites (mainly in the UP) as B12/B71 ONLY.

    I get CA. But not always. Maybe they’re still doing work. Either way it explains the patchy in door signal. I can only hope things will get better.

    The good, you don't lose service. The bad, band 13 is almost continuously congested (in urban areas, rurally in northern ia I saw band 13 only sites that seemed to be holding up since there's almost noone there to bog it down..) , so as you approach edge of band 4 service you can see your speed drop at least 75 percent in a matter of 4 or 5 feet as the traffic is aggressively shifted to band 13. 20 or 30mbps here, ------- 4-6mbps here.

    Edit: the current speed is "good enough" but I am hoping I see more use of band 5 once they get cdma and evdo the hell off there 8-)

    That makes sense then. Verizon does it for coverage while T-Mobile is tryna keep it lower power to push band 4 and 2 to its limits for congestion. That would make it stay there and help the lower bands not get easily congested. At least that’s what I’m thinking, especially since they got a smaller bandwidth slice of band 12 and 71 in certain areas.
