CWNP Certification CWDP-304 Book

It reduces delay for user traffic

It increases the encryption strength for user traffic

It increases the signal strength for wireless client devices

It allows for centralized filtering of wireless traffic

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,

1 priority level, but 2 queues (one for uplink traffic, one for downlink traffic)

1 priority level per client and AP pair, so the total number depends on the expected number of clients

1 priority level for voice RTP, 1 priority level for voice control and RTCP

1 priority level for VoWLAN client traffic, 1 priority level for wired VoIP client traffic
