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
AR5004G WLAN System Architecture
AR5004G reference design highlights:
- Windows®
drivers for Window XP, Windows 2000, Windows ME, Windows 98 SE
and Windows NT 4.0

on applicable IEEE 802.11 standards. Actual user throughput will be
lower than the theoretical link rate and will vary, as network
conditions and environmental factors can lower actual throughput rate. |
