AREDN does not the Internet and doesn't pretend to offer Internet speeds. No one is watching Netflix over AREDN; that's not what its for. But it is useful to get some idea of the resouces different applications will consume.
AREDN
0.25 Kbps per node
AREDN itself consumes bandwidth in order to maintain the network. This is a fairly chatty protocol which, essentially, involves ever node in the network broadcasting some information about itself across the entire network every so often. It's not much data, but it does add up.
Because every node will see this housekeeping data from every other nodes, it's easy to work out how much link bandwidth it will consumed simply by measuring the data across a given link for a given time for a given network size. and then doing some simple math.

VoIP
57 Kbps per call
Voice over IP calls, using Asterix or similar, are a popular use case for the mesh. They use relatively little bandwidth, but are more sensitive to latency issues. There are many calculators which can help you calculate your exact bandwidth requirement (e.g. here) depending on codec selection.
