At first, VoLTE will be used to deliver "Rich Communications Services" (which look like something similar to what Voice over IP/Video over IP outfits offer today) rather than completely replacing narrowband voice. It will be awhile before Verizon is willing to commit to that, due in part to LTE outages in late 2011.
On the flip side is MetroPC, which has pushed VoLTE as hard as it could.
Then there's Sprint, which will stick to voice over 1x for the foreseeable future, but routes Direct Connect over IP. Sprint's latest DC incarnation seems quite similar to one facet of RCS over LTE.
Yeah VoLTE took forever on Airave 4s, but it's definitely working now. Supposedly it was enabled months ago, but not necessarily for existing devices (only new ones). I had to factory reset mine to get it back in the queue, but after 2.5 weeks it got it. My Magic Box with wired backhaul, on the other hand, got it only 3 days after a factory reset. It seems that a lot of femtos setup before VoLTE launched never got put back in the queue (particularly femtos using WiFi or Ethernet backhaul), hence the necessary factory reset. I'm not sure if an Airave 4 would offer substantial coverage improvement over the Pebble, other than having CDMA as a fallback. If you need to cover a larger area, you can use both actually. They should handoff to one another with VoLTE, just keep them sufficiently far apart to minimize interference. And you'll probably have to tell Sprint it's for use at a different address, but they won't actually check where it's deployed. Sent from my Pixel 4 XL using Tapatalk
My router typically only gets rebooted for firmware updates or major functionality changes that I have implemented. Otherwise stays up for years. Last time it was down is when Hurricane Ike remnants hit Ohio in 2008 and caused week long power outages, which killed local internet in a few days (I have two ISPs, UPSes, generator). ISP's battery backups and generator use had improved considerably since that time.
Making changes appears to be the greatest reason for router instability. So put internet connections on a UPS, reboot after major changes, and otherwise enjoy.
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
