Has anyone had any experience with ad-hoc wifi mesh networks? We're looking
at setting up a temporary, mobile wifi mesh network to help us commission a
site at work. Generally the work we'll be doing is inside buildings with
metal sheeting inside the walls, so we'd be looking at multiple
battery-powered relay points, and a mobile testing setup in a rack on
wheels or something. The idea is that we plug a network device into a node
at the eventual termination point and then wander around with a laptop and
test the device.

Anyone know which is the most popular/robust/fast standard? I'd rather not
recommend we buy a shitty propitiatory, vendor-specific flavour of mesh
network.
