MAC Features
The BCM43362 WLAN MAC supports features specified in the IEEE 802.11 base standard, and amended by
IEEE 802.11n. The salient features are listed below:
• Transmission and reception of aggregated MPDUs (A-MPDU)
• Support for power management schemes, including WMM power-save, power-save multipoll (PSMP) and
multiphase PSMP operation.
• Support for immediate ACK and Block-ACK policies
• Interframe space timing support, including RIFS
• Support for RTS/CTS and CTS-to-self frame sequences for protecting frame exchanges
• Back-off counters in hardware for supporting multiple priorities as specified in the WMM specification
• Timing synchronization function (TSF), network allocation vector (NAV) maintenance, and target beacon
transmission time (TBTT) generation in hardware
• Hardware off-load for AES-CCMP, legacy WPA TKIP, legacy WEP ciphers, WAPI, and support for key
management
• Support for coexistence with Bluetooth and other external radios
• Programmable independent basic service set (IBSS) or infrastructure basic service set functionality
• Statistics counters for MIB support
MAC Description
The BCM43362 WLAN MAC is designed to support high throughput operation with low-power consumption. It
does so without compromising on Bluetooth coexistence policies, thereby enabling optimal performance over
both networks. In addition, several power-saving modes that have been implemented allow the MAC to
consume very little power while maintaining network-wide timing synchronization. The architecture diagram of
the MAC is shown in Figure 17 on page 35.
