Pico Cell FunctionalityPico Cell Functionality
Pico Cell functionality includes optimization of the Operating System (OS) to support this functionality
as follows:
• The Cisco WCS Pico Cell Mode parameter reconfigures OS parameters, allowing OS to function
efficiently in pico cell deployments. Note that when the operator is deploying a pico cell network
the OS must also have more memory allocated (512 to 2048 MB) using the config database
size 2048 CLI command.
• Client mobility between multiple mobility domains when such exist.
• Addition of a WPA2 VFF extension to eliminate the need to re-key after every association. This
allows the re-use of existing PTK and GTK.
• With WPA2 PMK caching and VFF, the PMK cache is transferred as part of context transfer prior
to the authentication phase. This allows expedited handoffs to work for both intra- and
inter-Cisco Wireless LAN Controller roaming events.
• A beacon/probe response that allows a Cisco 1000 Series lightweight access point to indicate
which Cisco Wireless LAN Controller it is attached to so that reauthorization events only occur
when needed, minimizing inter-Cisco Wireless LAN Controller handoffs and thus reducing CPU
usage.
• Allows changes to Cisco 1000 Series lightweight access point sensitivity for pico cells.
• Allows control of Cisco 1000 Series lightweight access point fallback behavior to optimize pico
cell use.
• Supports heat maps for directional antennas.
• Allows specific control over blacklisting events
• Allows configuring and viewing basic LWAPP configuration using the Cisco 1000 Series light-
weight access point CLI.
