Wireless Bridge needed. Will it work ?

Unanswered Question
Dec 9th, 2009


I need to run connectivity between two racks in a datacentre (about 10 metres apart). About 15Mbps b/width needed.

I have installed a CAT5e cable between the two racks (with two redundant switch-pairs in each). Only thing is, if that cross connect cable gets cut or the switches go down, I have no second path.

I need a second route:

I am thinking about running a couple of wireless bridges between the racks (and utilize Rapid Spanning Tree to "block"  the wireless route). All done via Layer2.

1) I assume my design with RSTP would work ?

2) Despite both antenni's being inclosed in metal racks, I am hoping the signal strenth would be strong enough across a 10 metre distance.

(bare in mind it's a data centre with lots of metal)

3) Any suggestions on products, this need to do this on a budget

Many Thanks for reading.

Hope someone can help.

Kind Regards


I have this problem too.

Why don't you just run another cable between the two racks using a different physical path? Wireless bridges are not the cheapest things in the world and typically are designed for outdoor use. 10 meters is not that far of a distance for a cable run.

Thanks for the response.

Not possible: I cannot run a second cable.

I am hoping 2x Cisco WET200 bridged will do the job, they are cheap (approx £80 each)

If it works it will be a nice reduundant layer2 path
