If I install a 3G/4G<E Base HAT with a Quectel EC25 Mini PCIe 4G/LTE module onto a Raspberry Pi 4, will I be able to connect devices to the Ethernet port of the RPi and have network access?
For example, can I connect an Ethernet switch to the Ethernet port on the RPi and have several devices gain network access?
Like computers, printers etc.
How about am ATA? would I be able to have VoIP calls come to the ATA over a cellular connection?
What about having both wired AND wireless connections active at the same time?
My main concern is having the Ethernet connection on the RPi function as a “WAN” port. (If that makes sense.)
