[Berlin-wireless] need help on: 5GHz Backbone
Mi Jul 18 01:57:29 CEST 2007
I´m stuck in my current work and heads are smooking. ;)
we can get and transmit ( sucessfully tested last week) a 16.000 DSL line in
your mesh from the neigbor village ( around 2 km away). At the moment we
share just a single 3000 DSL line.
Build up a 5GHz backbone net, to transfer the fast internet to 3 good
ff-nodes in our mesh (2,4 GHz indipendently), which every of the 3 ff-nodes
should anounce an internet-gateway to have most households with 1 Hop
connected to a gateway.
42 Freifunk nodes in one mesh cloud.
Two WRT54G v1.0 with the Broadcom 1470 5GHz minipci cards each are proper
working in WDS mode channel 34 under dd-wrt. ( Why dd-rt ? -> freifunk is
working too in a-mode, but the performace is just half of what dd-wrt can
transmit on those 125MHz units. FF gives up @1,8MByte/sek from node1 <->
node2 @5GHz adhoc; dd-wrt in wds mode @5GHz reach 3,2 MByte/sek between
This two 5GHz Routers have a perfekt link between two locations with
good-working ff-nodes on each side.
But how do I implement this new network link over 5GHz in our current mesh ?
I tried a lot in the last 5 hours.. this scenario is not working: ff-node1
[Wan-Port]<----->[Wlan-Router DD-WRT-1]<......< WDS 5Ghz Funkstrecke >
......>[Wlan-Router DD-WRT-2]<----[Wan-Port]>ff-AP2.....I gues there is no
proper olsr talk possible over the wds link !?
When just set up a WAN backbone net, it´s working so far, but in this case,
just internet traffic goes through the 5GHz backbone follwoing the default
gateway. The intra net traffic from these ff-nodes 1 & 2 wich have a fast
connection via 2x dd-wrt router in 5GHz band is unused without olsr enabled
on this link.
So I hope not been the only one building up a 5GHz backbone to discharge the
