Yeah mesh to me means you talk to one AP wirelessly and that AP talks to another AP also wirelessly to eventually get to a wired connection to the internet. Of course that can also be wireless (SpaceLink, Verizon, etc) but out to the internet. I much prefer each AP has its own ethernet backhaul because both latency and throughput are significantly better. Of course it’s not as convenient since you have to have wired connections at each AP location.
Because any negative number x 0 is still 0?
