  1. Pretty much all phones sold in the US do now. They're just firmware locked to each carrier sometimes. Samsung phones and Pixels for example work on all carriers and support all the bands. Sent from my Pixel 3 XL using Tapatalk
  2. Ahh I didn't know there were any T-Mobile plans/lines that worked for these modems. Was it a hotspot plan or just a regular line that you put in the modem? Sent from my Pixel 3 XL using Tapatalk
  3. How did you get the invite? Sent from my Pixel 3 XL using Tapatalk
  4. Settings, Network, Mobile Networks, Add. Sprint is listed. Select it and sign into your Sprint account. Select the line you want to put on the phone. This will not work if you're currently using the same phone with a physical SIM on Sprint. You have to swap the line to another phone first, and then you can activate the Pixel with eSIM. The reason is that the phone's IMEI is already on the line, and the eSIM activation apparently fails if all it's doing is swapping the SIM ICCID. It has to change ICCID and IMEI in Sprint's system. On the Pixel 4 or 3a, since it has two IMEIs, you probably can actually switch directly from physical to eSIM without an intermediary. Sent from my Pixel 3 XL using Tapatalk
  5. Sprint does support eSIM. I've been using it on my Pixel 3 XL since February I think? Sent from my Pixel 3 XL using Tapatalk
  6. No, about 9 Mbps up. It's still B41 with TDD config 1, which is limited to 9 Mbps or so. That config should allow for faster download (matching a macro), but I suspect that the hardware on the MB and Airave (both 3 and 4) can't handle more than that. All the Sprint femto cells max out at that speed. Either the CPU might not be able to handle the ipsec tunnel faster than that. Or it could be the eNB being underpowered and not being able to handle transmitting faster than that. My guess is it's a CPU limitation on the ipsec tunnel. Sent from my Pixel 3 XL using Tapatalk
  7. With wired backhaul, a MB (and Airave) gets around 80 Mbps or so. As you get a little further from the MB it drops to around 60-65, or at least mine does. Sent from my Pixel 3 XL using Tapatalk
  8. I wondered this as well, and I don't think it will go back automatically. This is based on setting it to wired/wireless backhaul before the endpoints were setup. It would get stuck and never finish setup. Usually wouldn't even switch off it and needed a factory reset to go back to relay. There's a possibility with the new firmware rolling out soon that it will fall back eventually, but I'm guessing it would still need to reboot itself and basically reconfigure. So it definitely wouldn't be a quick handover if it did work. With how congested 2.4 GHz wifi is, I'd advise anyone who wants non-relay backhaul to connect it with Ethernet instead. I haven't seen 2.4 GHz capable of maxing out the MB (60-80 Mbps) in many many years, there's just too much interference on it now. And since it's not using relay anymore, it can be centrally placed in your house instead of by a window, giving better coverage. Sent from my Pixel 3 XL using Tapatalk
  9. Yes, the tool is free to use. It's for modeling locations for a Ubiquiti point to point or point to multipoint wireless product. https://link.ui.com Yes, it's 2x2 MIMO. The modem I use (Sierra Wireless MC7455) is only capable of 2x2. That modem has issues with Sprint though (loses connectivity a few times a day). There are few 4x4 capable modems available, but the issue I always had with Sprint was support for all 3 bands. Only the MC7455 supports all 3. If you can guarantee that you get B41, then your options open up a lot. B25 support was more challenging. I modeled mine at 20 ft off the ground. They're mounted probably.... 5 ft and 6 ft respectively from the floor on the PVC, on the second story of the house, and would probably work if I lowered them. But they're in a corner and mostly obstructed from view inside the house (there's a bookcase behind it blocking the view). Be vigilant of the length of coax that you use. The signal will attenuate quite a bit the longer the cable, and can negate the gain from the antennas. More than you would think. It's best to have the modem as close to the antennas as possible, with as short of a cable as possible. Same reason why RRUs mounted on a cell site are used. You'll also need adapters. The antennas I think use N type, and the modem uses u.fl, but is in an enclosure that has sma. The coax I used had N type on one end and sma on the other. But you'll want to look at the specs of everything to confirm. Sent from my Pixel 3 XL using Tapatalk
  10. Yes, two antennas. They look like two stacked diamonds, with the bottom one rotated 90 degrees from the top one. The last picture on the product page shows the orientation. I have them mounted to a PVC pipe in the corner on the second floor of the house. I was going to mount them outside, but since tested it inside and it worked fine, so I didn't see a reason to move it outside and deal with running the coax through the wall. The height will depend on your topography. I modeled my particular scenario using a tool on Ubiquiti's site, plugging in GPS coordinates and approximate height measurements.

  11. I use two of these https://ltefix.com/shop/antennas/700-2700mhz-15dbi-4g-lte-directional-antenna/ They work pretty well. Right now I'm using them on AT&T on a site that is 3.4 miles away. I get about -110 to -115 on a B2 20 MHz carrier, which gives me ~20 Mbps down. On my phone with an AT&T SIM, I can just barely get a B12 signal that doesn't work particularly well. The frequency of those antennas works for Sprint as well. The Sprint site is much closer in my case, but due to antenna positioning and topography doesn't work as well. Just make sure you orient the antennas properly for MIMO. Sent from my Pixel 3 XL using Tapatalk
  12. The lack of ping response doesn't necessarily mean anything. My Airave 4 doesn't respond to pings on one of its IPs, but does on the other (but only if I do it from the same subnet/vlan as the Airave, which is odd. Using a different subnet it won't respond). My Magic Box responds, even from a different subnet. My guess is that something on your network is interfering with the Airave's ipsec VPN tunnel. It sets up two, one for LTE and one for CDMA. Perhaps something is only allowing one tunnel to be created, though I can't think of why/how. Or for some reason the CDMA side doesn't have internet access. I would contact Airave support and see if they can login to your Airave and see what the problem is. If you're able to do a packet capture on your network, that can be used to help diagnose the issue as well. Sent from my Pixel 3 XL using Tapatalk
  13. I would try factory resetting it. Sent from my Pixel 3 XL using Tapatalk

    No SIM is needed. You can set it up with eSIM. Such a shame they removed original quality photos backup. That was one of the things keeping me on the Pixel line. Thinking about jumping to One Plus now. Sent from my Pixel 3 XL using Tapatalk
  15. It's not more likely to stay in 1x in the future. Sometimes the phone associates a 1x or 1x800 connection with a certain LTE connection, but in my experience once it switches to 1x800, it will hang onto it until it loses it (either no signal, or a new PRL region is encountered). The region thing was useful to me, because I'd be on 1x800 in more rural areas but I'd enter a different geo region when I got back to the city, so that caused me to switch back to 1x1900 (1900 is scanned before 800 in the PRL, but they have the same priority). Otherwise, you have to manually switch back to 1900 each time you enter Airave coverage if you usually drop to 800 coverage outside your house. And yes, they should swap it no problem.
