[Olsr-users] Using multiple radio cards

[Victor]

Hey Derek,

Aaron is right on the money about using two different cards on two different
channels.

This is not exactly true. You can have OLSRd and AdHoc networking on
different channels. Just that the router boards on different channels must
be interconnected with LAN cables but still operating on the same OLSRd
network.

                 BACKBONE ************ BACKBONE
                   |                      |
                   | (LAN)                | (LAN)
                   |                      |
ROUTER +++++++++ ROUTER                 ROUTER ++++++++++ ROUTER


In the above diagram the "+++++" and "******" represents wireless
communication on different channels. And the | represents communications
over Ethernet (but again over olsrd). Now as long as the BACKBONE routers
are not too close to the customer level routers (or your using direction
antennas) then you wont get too much of an issue with interference
(obviously they still need to be on non-overlapping channels [1,5,11 if you
are in the US]).

IF you can a and b/g band radios, it is usually common practice to use 'a'
as the backbone and 'g' for customer connections.
