Femtocell Multi-band SOHO

@dew7rtx  The AT&T Cell Booster is designed for land-based internet service, which is DSL, cable, or fiber. It can work with satellite or wireless broadband but if there are issues with registration/activation or usage, AT&T will not support it because those types of connections are not what the Cell Booster (femtocell) was designed for. You would have to work with your satellite or wireless provider for ANY issues you encounter and they will probably just tell you to call AT&T as it is their product and not the providers.

@OttoPylot    Many Thanks for your reply and the links to your guides.  I have taken a look at both.

I have a fixed wireless ISP (Cirranet in North Texas), with consistent speeds; 15mbps dn, 2 mbps up and latency of 15-30 ms.  Seems like these parameters would be adequate for the ATT cell booster.   In our area the ATT signal is poor -110 to -120 decibels.  We have been using wifi calling but have been experiencing a lot of dropped calls or call failed.  Spent a couple of hours with Apple support attempting to assess why so many dropped/failed calls on our iphone 12 pro max.  Their diagnostics didn’t turn up anything with the phone and since we have the same issues with both phones I am thinking it's not the phone but maybe something with the Deco router or ISP.

I thought I would give the cell booster a try but have not been able to get it connect to the internet.  So far ATT support hasn’t been helpful…. The booster is connected to a Deco x60 V 1.0 mesh router (3 routers) …currently plugged into the main Deco router.  I did have a look at the min router requirements you list…here’s my assessment…

If you have any additional thoughts or guidance I would appreciate it……

DHCP enabled (YES)

Ports that must remain open (public and private):  (Not sure, but since we have some success with wifi calling I am guessing 500 and 4500 are open. I do see options to modify using port forwarding in the router settings).

123/UDP - for NTP traffic and timing

4500/UDP - for IPSec NAT Traversal (for all signaling, data, and voice traffic).

500/UDP - for IPSec Phase I prior to NAT detection, after which 4500/UDP is used.

IPSec Pass-Through is enabled. (Specific option not available for configuration in my router that I can tell)

Block Fragmented Packets is disabled. (Don’t know)

How is signal outside?

You might be better off with an actual cellular booster (AT&T's new device is not a booster) which will improve your wireless/cellular internet service overall.

(The new "cell booster" is a misnomer.  It requires better home internet than your wireless)

A cell booster only needs electricity.

It works by placing an antenna outside, as high up as possible not unlike a satellite TV DISH oh, and then a cable to an inside antenna which provides the Amplified service inside your home.   A directional antenna might actually be able to pull in a stronger signal than you are getting now.  

Look into Starlink internet.  It's satellite that's actually pretty good. 

I have my at&t  femtocell on Starlink, works perfectly. I also used the old microcell on starlink and before starlink, used it on a WISP (Wireless ISP). It worked fine  there as well. The WISP always had problems which is why I moved to starlink, but when the WISP was working, the femtocell worked.

@dew7rtx  As I've mentioned in both Tech Guide, the MicroCell and the Cell Booster, satellite and/or wireless broadband is not supported by AT&T because both femtocells are designed specifically for land-based internet (DSL, cable, or fiber) service. They can work, in fact there are some reports that the Cell Booster is working with Starlink, but those are rare. The connection protocols for satellite/wireless are different than land-based so if you can get it to work reliably, then you're lucky. The minimum router requirements are designed for land-based service.

You are basically on your own because there is nothing that Apple or AT&T can do. You'll have to work it out with Cirranet and they will probably tell you that it's not their service problems and tell you to call AT&T. 

These issues came up before with the MicroCell and there was nothing that could be done. The MicroCell would work just fine for a period of time and then the connection and reliability would be lost (atmospheric issues, slight movement of the satellite from its geo-stationary orbit, interference, latency, etc). 

As mentioned, if you can get one and preferably two bars of reliable cellular signal you might want to consider purchasing a Cellular Booster (see my Cellular Booster Guide, link is in my sig line).

Bottom line, there is another that we, AT&T, or Apple can do to make the Cell Booster work reliably with your wireless broadband. Sorry.
