AR5002G 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 supports 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

• 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

• Support for draft IEEE 802.11e, h, and i standards

• Third-generation OFDM radio provides best-in-class range, throughput and power consumption

The chipset includes:

AR2112 Dual band Radio-on-a-Chip (RoC)

• 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 that conventional equalizer-based designs

• Integrated third-generation 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

AR5212 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, dynamic transmit optimization and standards-compliant bursting

• 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

AR5002G WLAN System Architecture

* Theoretical wireless link rate based 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.
