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
