4.3.13 Wireless network management
4.3.13.1 Overview
Wireless network management (WNM) enables STAs to exchange information for the purpose of improving
the overall performance of the wireless network. STAs use WNM protocols to exchange operational data so
that each STA is aware of the network conditions, allowing STAs to be more cognizant of the topology and
state of the network. WNM protocols provide a means for STAs to be aware of the presence of collocated
interference, and enable STAs to manage RF parameters based on network conditions.
In addition to providing information on network conditions, WNM also provides a means to exchange
location information, provide support for the multiple BSSID capability on the same wireless infrastructure,
support efficient delivery of group addressed frames, and enable a WNM-Sleep mode in which a STA can
sleep for long periods of time without receiving frames from the AP.
The WNM service includes the following:
— BSS Max idle period management
— BSS transition management
— Channel usage
— Collocated interference reporting
— Diagnostic reporting
— Directed multicast service (DMS)
— Event reporting
— Flexible multicast service (FMS)
— Location services
— Multicast diagnostic reporting
— Multiple BSSID capability
— Proxy ARP
— QoS traffic capability
— SSID list
— Triggered STA statistics
— TIM broadcast
— Timing measurement
— Traffic filtering service
— U-APSD Coexistence

— WNM-Notification
— WNM-Sleep mode
