? 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).
? Clock/power gating combined with 802.11-compliant power

management dynamically 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.
