is 802.16d a mesh?

does anybody know if 802.16d protocol inherently a mesh or does it have
to be reconfigured? would Click (used by Roofnet) be able to do or does
it need a new OS?

No. There's nothing in 802.16d that requires a mesh network topology.
It can be point to point, point to multipoint, or mesh depending on
the MAC layer firmware installed.

Roofnet is not 802.16d WiMax. It runs 802.11b/g.

MIT Roofnet:

If you're looking into building your own protocol encapsulated inside
802.11 packets, see MadWiFi-stripped:

jeff (and anybody else):
do you know if anybody's tried a pure mesh using 802.16? is there
anything like MadWiFi-stripped for 802.16?
+
can you glue a WiFi to WiMAX? like using WiMAXs for backhaul traffic
and WiFis as hotspots?
+
do you know if there's a SSCH for WiMAXs like the virtual WiFi M$ is
experimenting with?
many many thanks,
michael

I've had no personal experience with WiMax mesh networks. However, if
you search Google for "WiMax mesh", you'll find plenty of universities
doing tests, companies doing trials, and the usual science fiction
product announcements.

I don't know.

Sure. Both WiMx and Wi-Fi encapsulate 802.3 ethernet packets. Just
put two back to back wireless access points and connect them with an
ethernet cable. No big deal.

Google doesn't find anything on this for WiMax or 802.16.
