  • Universal wireless connectivity for seamless roaming between any 802.11- based network
  • Uses digital CMOS technology exclusively, minimizing power consumption and cost while maximizing reliability
  • Highly integrated 2-chip set
  • 2.4/5 GHz Radio-on-a-Chip (RoC)
  • Integrated 32-bit MIPS R4000-class processor with multiprotocol
    MAC/baseband processor that supports the RoC
  • Wireless Multimedia Enhancements Quality of Service support (QoS)
  • Super AG� mode delivers up to 108 Mbps raw data rate with typical
    end-user throughput exceeding 60 Mbps
  • Super AG� utilizes Adaptive Radio to automatically identify clear channels
    for maximum throughput and standards compatible operation
  • Hardware encryption for the Wi-Fi Protected Access (WPA) and
    IEEE 802.11i security specifications, provides Advanced Encryption
    Standard (AES), Temporal Key Integrity Protocol (TKIP) and Wired
    Equivalent Privacy (WEP) without performance degradation
  • Extended tuning range (2.300-2.500 & 4.900-5.850 GHz) for worldwide use
  • Dynamic Frequency Selection/Transmit Power Control (DFS/TPC)
    for international operation
  • Support for draft IEEE 802.11e, h, i and j standards
