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

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:

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. |
