AR5005UX Solution Highlights
- Support for IEEE 802.11a,
802.11b, 802.11g
- Universal wireless
connectivity for seamless roaming between any
802.11- based network
- Uses digital CMOS
technology exclusively, minimizing power consumption
and cost while maximizing reliability
- Highly integrated 2-chip
set
- 2.4/5 GHz Radio-on-a-Chip
(RoC)
- Integrated 32-bit MIPS
R4000-class processor with multiprotocol
MAC/baseband processor that supports the RoC
- Wireless Multimedia
Enhancements Quality of Service support (QoS)
- Super AG® mode delivers up
to 108 Mbps raw data rate with typical
end-user
throughput exceeding 60 Mbps
- Super AG® utilizes
Adaptive Radio to automatically identify clear
channels
for maximum throughput 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
- Extended tuning range
(2.300-2.500 & 4.900-5.850 GHz) for worldwide use
- Dynamic Frequency
Selection/Transmit Power Control (DFS/TPC)
for
international operation
- Support for draft IEEE
802.11e, h, i and j standards
- Atheros XR™ eXtended Range
technology to give Wi-Fi products twice
the range
of existing designs
AR5112
Radio-on-a-Chip for 2.4 GHz WLAN
- All CMOS dual band radio
chip
- Dynamic IF Dual Conversion
architecture provides super-heterodyne
performance at Zero IF prices
