was wondering if two nodes in a given wi-max or for that matter in a wi-fi network can communicate with each other without actually going through internet back haul?

I hear Intel's 802.11s proposal allows existing wifi nodes to communicate with each other via a mesh.

But I suppose given long range wifi routers, with appropriate alternative channels and subnets, you could theoretically create your own WAN mesh without using the ISP's backbone.

intel? IEEE? 802.11s actually defines standards for wireless mesh networks. Intern client /node communication is one of the features of WMNs. I think the basic topological architecture determines this as in wi-fi its more of line of sight and the nodes don't actually involve in routing right? in 802.11s , clients too communicate , may be thats the reason inter-client communication is possible without going through internet.
argh.. the more try explaining the more questions pop up😔

Yeap, its an IEEE mesh draft standard but Intel has given their initial technical proposals for it. As of now, I don't think the standard is ratified yet.

The thing about this standard is that its built upon existing 802.11a/b/g standards, so each 802.11a/b/g node can also act as a router.. with traffic hopping on to the subsequent node. Basically the microscale of packet networks without the internet back haul. So in this sense, it is possible for non mesh Wifi nodes to communicate this way.

Multiple hops at MAC layer will be facilitating it. Currently its single hop hence unless and until we go till the backbone the packet is unaware where it needs to go. But in the mesh techonlogy clients will be able to do it by themselves. Atleast with all those neigbours whose MAC ID they are ware of.

not possible
Its possilbe only in Wireless Mesh Networks and not in Adhoc networks like Wi fi
