Page 38: Site Preparation And Planning
This section provides implementation details and configuration examples. Site Survey Cisco recommends that you perform a radio site survey before installing the equipment. A site survey reveals problems such as interference, Fresnel zone, or logistics problems. A proper site survey involves temporarily setting up mesh links and taking measurements to determine whether your antenna calculations are accurate.

Page 149: Throughput Analysis
For example, 4 RAPs at 10 Mb/s each deliver 40 Mb/s total capacity. So, one user at 2 hops out, logically under each RAP, could get 5Mb/s each of TPUT, but consume 40 Mb/s of backhaul capacity.

Page 150 Troubleshooting With the Cisco Mesh solution, the per-hop latency is less than 10 msecs, and the typical latency numbers per hop range from 1~3 msecs. Overall jitter is also less than 3 msecs. Throughput depends on the type of traffic being passed through the network. Traffic can be User Datagram Protocol (UDP) or Transmission Control Protocol (TCP).
