Two RAPs per Cell on Different Channels
Multiple RAPs
Before deploying multiple RAPs, the purpose for deploying these RAPs needs to be considered. If
additional RAPs are being considered to provide hardware diversity, they should be deployed on the
same channel as the primary RAP. The reason for this is to minimize the convergence time in a scenario
where the mesh transfers from one RAP to another. When planning RAP hardware diversity, the 32
MAPs per RAP limitation should be remembered.

the backhaul channels.
When adding a second RAP on a different channel, channel planning or RAP cell splitting can be used
to reduce the extent of potential collision domains. Channel planning allocates different non-overlapping
channels to RAPs in the same collision domain to minimize the collision probability. RAP cell splitting
is a simple, yet effective, way to reduce the collision domain. Instead of deploying one RAP with
omni-directional antennas in a mesh network, two or more RAPs with directional antennas can be
deployed. These RAPs are collocated but operate on different frequency channels, thus dividing a large
collision domain into several smaller ones that operate independently.

If the Wireless Mesh bridging features are being used with multiple RAPs, these RAPs should all be on
the same subnet to ensure that a consistent subnet is provided for bridge clients.
