AR5006EXS Technology Overview
Introducing the Atheros AR5006EXS, the world’s first single-chip IEEE
802.11a/b/g WLAN solution with support for PCI Express. AR5006EXS
integrates a complete WLAN solution-media access controller (MAC),
baseband processor, and a high-performance 2.4/5-GHz radio in a
low-cost digital CMOS design.

With the highest level of integration, the AR5006EXS enables the entire
WLAN solution to fit on a single-sided Mini Card or ExpressCard design,
creating the ideal choice for embedded and aftermarket WLAN solutions
for personal computers. This design exploits the ability of the PCI
Express bus architecture to support high-performance computing with
up to 2.5-gigabit-per-second transmit and receive rates – a 150 percent
improvement over the existing PCI architecture.

AR5006EXS Solution Highlights

• Uses digital CMOS technology exclusively, minimizing power
  consumption and cost while maximizing reliability
• Highly integrated single chip PCI Express CMOS solution with
  MAC/baseband processor and 2.4 GHz radio
• Compliant with IEEE 802.11b, 802.11g, 802.11d, 802.11h,
  802.11i and 802.11j standards
• Supports draft 802.11e Quality of Service (QoS) standard
• Super AG® mode delivers up to 108 Mbps data link rate with
  typical end user throughput exceeding 60 Mbps
• Atheros XR™ eXtended Range technology gives Wi-Fi products
  twice the range of existing designs
• Hardware encryption for security 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 & 4.900-5.580 GHz) enables worldwide use

AR5424 Single-Chip 802.11a/b/g PCI Express CMOS MAC/Baseband/Radio
