Which definition correctly describes the "local MAC" variation of the centralized WLAN architecture?
All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the WLAN controller along with
management and monitoring functions.
PHY functions are performed directly by the AP. MAC functions are divided almost equally between the WLAN controller and the AP,
according to the time sensitivity of the feature or service.
The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions or services. The WLAN controller
performs all MAC functions and the AP is very simple and lightweight.
All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network services with one another and are
managed by a WNMS,
