Due to the recent protects in Hong Kong I decided to research Firechat and subsequently how Wireless Mesh Networks work.
The only thing I remembered about mesh network was that it was a type of topology I learned many moons ago at college (along with bus, star, ring and token from memory)
Anyway, I got reading http://computer.howstuffworks.com/how-wireless-mesh-networks-work.htm and it looks like a mesh network uses nodes in wireless radio frequencies that are also used in wireless devices (like phones)
Just a couple of questions
1. If Wifi is switched off on mobile device, how does the 802.11a/ b/ g still stay working? Is it just radio signal parts of the wifi that stay on, but actual wifi searching/connecting is turned off
2.
If no nodes are connected to the internet, I take it that the network still works but nothing will be updated with any outside data. I.e a Firechat 'nearby' group can chat to all nearby nodes but that's it - no communications from anywhere else?

In a wireless mesh network, only one node needs to be physically wired to a network connection like a DSL Internet modem
