Just got my A4 and also seeing red light on LTE. Has anyone gotten this resolved yet?

I am in the same situation.

The LTE light has never gone green, always flashing red.  Called support once and the explanation was is that LTE service wasn't provided in my area.?.?   Going to try calling back today and see if I get different results.   

I am wondering if the Airave 4 are essentially a Magic Box and a CDMA voice airave merged together. Since I am not in a Magic Box area, maybe that's why LTE don't work.

It works on my Airave 4. 

I dialed *99 with my Airave 4 and got error message. Based on signal check, I am definitely on my Airave

Selfishly reposting.. if those of you getting new Airaves could send SCP diagnostic reports once connected to it, I would appreciate it! Please include your username or an email, and a note that says it's from an Airave 4.

I only need one per Airave, so thank you to the two of you who have already sent reports. If you're only getting CDMA for now, I'll still take a report, feel free to send another once you get LTE going.

Here is a CDMA only report

They lack low band spectrum which is important when scaling up coverage.

Dish doesn't have much low band, I believe. They do have some 600Mhz. But the bulk of their spectrum is in AWS and PCS H block as well as some satellite bands converted for terrestrial use

If the merger fails Sprint should be allowed to have it. Could use the added BW

Sprint have enough spectrum but not enough cash.

Then make dish cough up all that spectrum.

I do hope FCC is going to enforced the deadline and hand the spectrum to whoever really want to be a carrier. I doubts the current FCC will do that.

Finally received my replacement unit this afternoon. Took about 20 minutes for it to configure itself, but all lights green now except LTE.  Also blinking red.  

I am in an area where Magic Box is not allowed. Don't know if same thing keep LTE off-limits to my Airave. When the rep ordering me the Airave, she did say that when punching in my address there are some weird error messages about the area not compatible. But she went ahead and ordered the Airave anyway.

If I'm not mistaken doesn't dish have spectrum Nationwide

Yes. But Dish didn't show any will to actually be a carrier.

I feel like an existing regional player should be a better 4th carrier, if they get the divested spectrum, network gear and a good wholesale roaming deal. I think DOJ should better get TMO/S to agree on on a network sharing/mvno/roaming deal open to all regional players than manufacture a 4th player.

That would be a disaster. Besides Comcast has a mnvo agreement with Verizon

They could be switching MVNO agreement. Or they will become a regional carrier and use MVNO agreement as the basis for roaming.

My Airave 4 has CDMA up and running in no time. But LTE still don't work for couple days now. All lights are green excpt LTE which is blinking red

The Sprint LTE network throughout Oregon is VERY well optimized. I wish Sprint's network team was that good everywhere. 

The bug is likely a Samsung bug. It may be a good idea to reach out to someone at Sprint and inform them of it. 

Yes. I agree. Sprint's Oregon Network is very good. I don't know how I would report it. I don't want to spend hours talking to CS rep that don't know what's going on.

Or perhaps are you in an area where Sprint LTE has better range than Sprint CDMA?  IE, your phone never falls off Sprint LTE to CDMA first before roaming, which would be typical.

It happens everywhere in Oregon. In many cases they start to roam before falling off to CDMA.

Now that's interesting, and could be the issue. On Verizon my Pixel 3 will turn off CDMA, but on Sprint with VoLTE it keeps CDMA on and maintains SRLTE. So if I start to roam, presumably it will quickly drop to CDMA. For some reason it sounds like that isn't happening on your Samsung phone. I'm surprised it turns off CDMA actually.

Yes. When my S10 is actually on Sprint VoLTE, it turns off CDMA. I think this is what suppose to happened with standard VoLTE implementation. For some reason, my Samsung don't know it needs to turn CDMA back on once I roam onto T-mobile. I suspect because T-mobile has VoLTE. Samsung mistakenly believe it could use it for voice. This behavior is less frequent with USCC.

In that case I'm not sure. I won't have mine until the end of the week, so I can't do a packet capture to analyze. I'd say just leave it overnight and see if it's working in the morning.

Thanks. Let me know what you found. I doesn't really need LTE since there is pretty good T-mobile LTE. I just need voice coverage.

I double checked and your phone should utilize SRLTE at all times when LTE roaming (I believe even when the LTE and CDMA provider's are the same although I'm not 100% sure). There may be a software/config bug if your phone isn't. 

Does toggling airplane mode in the roaming area cause SRLTE to turn on?

I suspect a Samsung bug. Once I toggle airplane mode or make a outgoing call, it will return to normal.

Could be being blocked by your corporate firewall or it's having NAT issues. 

But CDMA side works fine. And I don't have problem with Airave 3

Well if anyone interested in the debug screenshots https://imgur.com/a/EdrPKwt

How did you get to the screen that has 1xAdv status? Galaxy

My Airave 4 is up and running with CDMA only. LTE is always blinking red. Not sure why. Does it has a separate MAC address for LTE side? My cooperate network requires MAC address whitelisting. I whitelisted the MAC address on the label. The CDMA voice works fine. LTE don't. I don't needed LTE anyway. The building has good T-mobile B66.

What do you mean a VoLTE enabled area? I thought you were roaming...

I'm confused what you mean here...

So, what I mean is about moving from one cell to another.  I was in Sprint native coverage with VoLTE enabled. And calls are indeed go through VoLTE. My S10's CDMA radio is off. Now, I moved to a roaming area and latched on T-mobile. Supposedly, my phone should be using T-mobile for data only and turn on CDMA radio and use USCC or Verizon for voice. But the CDMA part never happened. My phone is latched to T-mobile's LTE network only. No incoming voice.

Interesting. I haven't had issues dropping from T-Mobile LTE to USCC CDMA to recurve/make calls on my iPhone. I believe they using SRLTE, not eCSFB, though...

Did the problem persist if you disabled VoLTE?

When my phone was not in a VoLTE enabled area, it works fine. But if my phone is in VoLTE enabled area with VoLTE on(CDMA Radio Off), it becomes a problem. But again outgoing calls are fine. My galaxy knows to drop LTE and find CDMA. But since CDMA is not monitored, incoming fails. My phone does use SRLTE normally when not roaming. Last time when I has this roaming problem, I bring up my Samsung engineering screen and it says CSFB.

It works fine with VoLTE disabled. It only happens when my phone was in VoLTE mode (CDMA radio off) right before entering roaming.

Anyone has a roaming problem with VoLTE? I am driving through Oregon last weekend. It has VoLTE pretty much everywhere. However, sometimes when Sprint LTE is not strong enough, it will park on T-mobile and USCC. When I am roaming on T-mobile, incoming voice don't work as my S10 don't know to start searching for CDMA signal and T-mobile won't send CSFB signal. Outgoing call works as phone know it needs to drop LTE and look for CDMA signal. It happens sometimes on USCC. But in most case, it will know to find USCC's CDMA signal.

Do you have to use an external GPS antenna? Do they have an internal GPS antenna?

Update:  The Airave can't seem to get a GPS lock.  Tried everything. Curious to see if anyone else has issues with this when their units arrive. The unit will produce a CDMA signal without a GPS lock, but no LTE.  Curious how it can do that as I thought CDMA relied heavily on GPS timing. 

Are you sure CDMA is working without GPS? Do they give you a chirp sound when calling out?
