AR5005UG Solution Highlights

  • Support for IEEE 802.11b, 802.11g
  • Uses digital CMOS technology exclusively, minimizing power consumption and cost while maximizing reliability
  • Highly integrated 2-chip set
  • 2.4 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 G® mode delivers up to 108 Mbps raw data rate with typical
    end-user throughput exceeding 60 Mbps
  • Super G 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
  • Support for draft IEEE 802.11e, h, i and j standards
  • Atheros XR™ eXtended Range technology to give Wi-Fi products twice
    the range of existing designs

AR2112 Radio-on-a-Chip for 2.4 GHz WLAN

  • Support for IEEE 802.11b, 802.11g
  • Operates from 2.300 - 2.500 GHz
  • Advanced wideband receiver with best path sequencer for better range
    and multipath resistance than conventional equalizer-based designs
  • Integrated power amplifier (PA) and low-noise amplifier (LNA)
  • External PA and/or LNA can be used for special applications
  • Eliminates all IF filters and most RF filters; no external voltage-controlled
    oscillators (VCOs) or surface acoustic wave (SAW) filters needed
  • Enhanced transmit and receive chains

AR5523 Multiprotocol MAC/baseband processor

  • Integrated MIPS processor
  • Supports both 2.4 GHz and 5 GHz RoCs
  • Super AG® mode includes dynamic 108 Mbps capability, real-time hardware
    data compression, Fast Frames™ and standards-compliant bursting
  • eXtended Range (XR) technology
  • Integrated Wake-on-Wireless and Wake-on-Theft capabilities
  • USB 2.0 compatible interface
  • High speed UART with DMA supports data rates up to 1 Mbps
  • Integrated analog-to-digital and digital-to-analog converters
  • Serial FLASH/EEPROM, LEDs, GPIOs peripheral interfaces
  • Low power operational and sleep modes

AR5005UG Reference Design Highlights

  • Windows® drivers for Windows XP, Windows 2000,
    Windows ME, Windows 98 SE
  • A single driver and firmware code base supports
    all Atheros USB chipsets
  • Integrated WPA supplicant supports Windows XP,
    Windows 2000, Windows ME, Windows 98 SE
  • Client utility supports configuration profiles,
    current link status, statistics and diagnostics
