The bandwidth of my DSL is too low to share voice + image at the same time. I have a dedicated 4G/LTE line for internet access. Unfortunately, area is crowdy and thus pylon bandwidth is shared between local users. Fine, except when I need to videocall with a class.
My idea is to create an access point that would connect to the net via my dedicated 4G + my main subscription (4G) via tethering both phones, connected to the pi via usb
The closest article I found is
How does the RPi 3 handle simultaneous LAN and WiFi connections
which is close to the target but not adapted to my network knowledge. I want to bundle both connections to increase bandwidth.
How could I split the applicative network connections over the two 4G network connections ?
Thank you
