Description
Wireless Control Sys-
tem (WCS)
The wireless mesh SNMP management system allows networkwide
configuration and management.
WLAN Controller
(WLC)
Links the mesh APs to the wired network and performs all the tasks
previously described for a WLC such as management of multiple
APs, mitigate radio interference, manage security, and provide
Layer 3 mobility.
Rooftop AP (RAP)
Connects the mesh to the wired network and serves as the root. It
also communicates with the MAPs. RAPs are typically located on
rooftops or towers.
Mesh Access Point
(MAP)
Remote APs that provide access to wireless clients. They communi-
cate with the RAP to connect to the wired network. MAPs are typi-
cally located on top of a pole, such as a lamppost.
Mesh Design Recommendations
The following are Cisco recommendations (and considerations) for mesh design:
There is a < 10-ms latency per hop. Typically 2 ms to 3 ms.
■
For outdoor deploy ment, four or fewer hops are recommended for best performance.
A maximum of eight hops is supported.
■
For indoor deploy ment, one hop is suppor ted.
■
For best performance, 20 MAP nodes per R AP is recommended. Up to 32 MAPs is
supported per RAP.
■
Throughput: one hop =14 Mbps, two hops = 7 Mbps, three hops = 3 Mbps, four hops
= 1 Mbps.
