Dual WWAN cards
I have built like 3 pfSense Mi-Fi devices for friends and want to build a hotrod for myself with Sierra and Atheros cards.
I am thinking dual cellular radios as WAN would be a good way to insure constant signal when mobile. Was thinking of 2 carriers like ATT and T-Mobile. Maybe two MC7700 cards or perhaps one MC7700 and one MC7710??? My MC7700 cards seem to work on both carriers, even though the MC7710 is T-Mobile??WHY??
I am unfamilar with pfSense load balancing features. Am i out of bounds with such a project and my expectations? Could i have balancing favor one carrier/interface yet bounce back and forth depending on signal/packet loss? Provision like 70 percent traffic to one carrier and 30% to other unless signal lossage.
What techniques do i need to read up on?
Looking at the Pfsense MultiWAN 2.0 documents it looks like everything i need is there. I assume a WWAN would be treated the same as a WAN connection for setup? Gateway group for each MC7700 i guess.
