If you have extremely reliable home internet I suppose it's viable, but personally I've found the redundancy of being able to fall back to hotspotted mobile data when required extremely important.


There's also the matter of using a cell phone as an actual phone.


Get a dual sim phone and run your own cell phone network inside your home.

(don't actually do this).


Carrier support vary, but you could use VoWiFi.


Which is great until your power/internet goes out, and you need to make an emergency call from inside.


Just configure the cell phone to use VoIP.


If your carrier supports this, of course.


I don't think this has anything to do with the carrier? On Android you would just add a SIP account and then set it as the default for outgoing calls.


Or vote with your wallet and switch carriers or use third-party VoIP as your primary number.


You can put an external mobile modem and make it a failover wan connection. That way you still control the network via your wifi equipment but have that still available.


You can always cut off one room without encasing the entire space. Just for occasions when you need the extra safety.


You can run an external cell antenna through the wall to your hotspot.


What is the faraday cage achieving then? Any device in your home can connect to the cell network anyway. Sure, they probably can't connevt to satellite anymore, but I doubt that it is extremely popular.


Huh? Only the antenna, outside the faraday cage, would be able to connect to the cell network. A wire would then connect that antenna to your router.


I thought the purpose was for ypur phone to be able to connect to the cell network, for example for (non-VoIP) calls. But, if your phone can connect, so can any other sim-enabled device.


Maybe you would just have a (fixed) phone outside, forwarding calls/sms/internet to an internal device via fixed line.

Wifi hotspot would have a password, so only trusted devices can connect.

Maybe Apple devices can already do that?


No, the comment you replied to seems to be talking about using the cell network as a fallback for Internet access. That's why the stipulated an antenna on the outside of the house.


I was assuming that it meant having their phone fall back to the cell network when WiFi is iffy, and I was pointing out that this would require breaching the faraday cage entirely essentially.
