1. Overview
• WMM power low U-APSD.
•
Multiple queue management to fully utilize traffic prioritization defined by 802.11e
standard.
• UMA compliant and certified.
• 802.1h/RFC1042 frame encapsulation.
•
Scattered DMA for optimal CPU off load on Zero Copy data transfer operations.
• Antenna diversity and selection (software managed hardware).

adapted to current connection condition providing minimal power consumption.
• Adaptive rate fallback algorithm sets the optimum transmission rate and Tx power
based on actual SNR and packet loss information.
• Automatic retransmission and response on MAC to avoid packet discarding on slow
host environment.
• Seamless roaming support.
• Configurable packet traffic arbitration (PTA) with dedicated slave processor based
design provides flexible and exact timing Bluetooth co-existence support for a wide
range of Bluetooth Chip vendors.
• Dual and single antenna Bluetooth co-existence support with optional simultaneous
receive (Wi-Fi/Bluetooth) capability.
