WN2401A
  CHIPSET  AR5213A-00

AR5004G 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)

  • Multiprotocol MAC/baseband processor that support 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 throughout 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

  • Atheros eXtended Range (XR) technology to give Wi-Fi products twice the range of existing designs

  • Power-saving design improvements reduce system power consumption by 60%

The AR5004G solution includes:

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

AR5213 Multiprotocol MAC/baseband 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

  • Atheros eXtended Range (XR) technology

  • Integrated Wake-on-Wireless and Wake-on-Theft capabilities

  • No external FLASH or RAM memory needed

  • PCI 2.3 and PC Card 7.1 host interfaces with DMA support

  • Integrated analog-to-digital and digital-to-analog converters

  • Serial EEPROM, LEDs, GPIOs peripheral interfaces

  • Low power operational and sleep modes
