It’s been a while since I’ve posted here since I’ve switched away from Sprint but I happened upon your thread while researching an upgrade to my Rural Internet Setup and I thought you might be able to help some I currently have a MoFi 4500 with two 35ft long LMR400 cables going from inside my cabin up to two panel antennas on the roof https://imgur.com/a/NpOjzwM It’s working ok but I think I’m missing out on a lot of bandwidth since bands 14 and 66 have been added to the area and I could get better signal with a modem mounted behind the antennas (eliminating a lot of line loss). I’ve been looking at mounting a Telit LM960 or Quectel EM20 in a panel behind the antennas outside along with a Golden Orb compatible router powered by POE and adding another pair of antennas for 4x4 MIMO. Since you’ve tested both the EM20 and the LM960, which do you prefer? It appears the LM960 actually has better CA combinations for AT&T’s network even though it’s theoretically not as high level of LTE technology category as the Quectel. It appears to me most of the higher order carrier aggregation on the Quectel is with CBRS or LTE unlicensed which I don’t think I’ll ever see in this rural Edge of Cell area. Also does it appear to you that having these installed outside would be a reliability issue? It gets really hot here in the summers with plenty of severe weather and it can be cold in Winters. The LM960 at least appears to have a pretty broad operating temperature range. Any advice is appreciated, thanks! Sent from my iPhone using Tapatalk
Yeah, agreed, it's pretty ridiculous, but that's typical Sprint for you. I doubt T-mobile will put any work into fixing things like this, since they will want to get rid of B41 femtos to refarm the spectrum. Plus they're moving people to the T-Mobile network anyway. I imagine their CellSpot will work better with VoLTE, with the caveat that it doesn't have as good of range as Sprint femtos (at least the magic box). And/or they'll release a 5G version eventually. But either way, we likely won't see any changes or improvements to Sprint femtos going forward. If you have a UPS, it's worth putting the Pebble, your router, and modem on it. It's certainly nice to have working internet for a while when the power goes out, and then you won't lose VoLTE either. Sent from my Pixel 4 XL using Tapatalk
I just figured it couldn't hurt for it to have a fresh reboot every week at 4 am on Sunday while not in use. I don't know if it particularly NEEDS that but the point is that any type of power/internet failure knocks the damn VoLTE out for 2-3 weeks which is ridiculous. I'll disable it for now and see if the router becomes unstable.
Yeah that would definitely do it. It keeps getting pushed to the back of the queue. The guy I spoke to was more in engineering than tech support. He's helped me with a few other issues in the past, so I trust what he says. Why do you have your router set to reboot weekly? If you have to do that for it to be stable, perhaps look for a new/better router. Mine is at 337 days of uptime. I only reboot when there's an update.
Odd... I escalated as high as I could go, and spoke to a technical supervisor, who told me in no uncertain terms, there is NOTHING that is within their control (in order to enable VoLTE). She told me it is a technical limitation of the device which I said I thought was bullshit. She wanted to leave it at that but I told her I wasn't happy with that answer and wanted an actual explanation as to why they would even offer a product which they had no control over and which took 2-3 weeks to activate fully, and which resets every time the power goes out, and she said she would send my ticket to corporate compliance and they would call me back. I also realized my router is set to reboot once a week which knocks the connection out. I'm wondering if that is causing this Pebble to never activate VoLTE.
