[Olsr-users] Using multiple radio cards

Sat Aug 9 02:43:38 CEST 2008

Hi Aaron,

My plan is to supply my MESH via Mikrotik routerboards into my "gateway"
OLSRd nodes.  This is all in Dublin city and I know from existing test
sites that I can get around 15Mbps across 14KM links into the city centre
with Mikrotik hardware & software.

Now I'm trying to work out my DIY MESH system.

I'd love to use separate MESH backbone frequencies - BUT - it seems to me
that if I'm using OLSRd and AdHoc networking then I have to set-up
everything on a single channel/frequency (if I use separate channels then
every node will not see the neighboring nodes surely?).

This channel/frequency issue is now biggest on my concern list.  It's
nothing to do with customer delivery because I'm planning on suppling this
via 2.4Ghz on a separate radio card & antenna - I'm only concerned with
the best possible speed and layout over the MESH backbone network.

Do you have any ideas as to how multiple channels/frequencies can be used
with an OLSRd MESH network?

thank you very much,

Derek

P.S. I now have 4 city centre sites in Dublin initially (all south of the
liffey right now) and I have purchased 50Mbps from a fibre backbone
bandwidth provider.  If there are any people in Dublin interested in
taking part in this project please do email me directly.
