Atheros Communications, a developer of advanced wireless LAN (WLAN) chipsets, has announced it is now shipping in volume the world’s first complete IEEE 802.11g solution that fits on a single chip.
The Atheros AR5005G brings an unprecedented level of integration, performance, power savings, and cost reduction to the rapidly growing 802.11g market. It is suited for a wide range of wireless products, including handhelds. No currently available handheld includes built-in 802.11g.
This single chip includes a Media Access Controller (MAC), a baseband processor, a high-performance 2.4-GHz radio, and other necessary components.
The Atheros AR5005G features new signal processing technology that extends the battery life of mobile devices by dynamically adjusting power consumption in response to system and network activity. This technique delivers up to 98 percent lower power consumption than multi-chip WLAN solutions on the market today.
The chip also supports the latest WLAN security standards, including Wi-Fi Protected Access (WPA and WPA2) and 802.11i Enhanced Security using Advanced Encryption Standard (AES). The AR5005G also fully supports the Wireless Media Extensions (WME) Quality of Service (QoS) capabilities defined in the IEEE 802.11e draft standard, which have been created to facilitate the convergence of voice and data communications on wireless networks.
Also shipping in volume is an enhanced version, the Atheros AR5005GS, which supports Atheros’ Super G technology. This allows throughput rates of over 60 Mbps in a typical home environment. The AR5005GS uses Atheros adaptive radio technology, which actively looks for clear channels and uses them to provide maximum throughput-on-demand for all users.
Both of these chips support eXtended Range operation, XR, which enables connections at greater distances from the access point and provides wireless connectivity to areas of the home in which signals are otherwise too weak to connect.
More information about these 802.11g chipsets is available on the Atheros web site.
Earlier Atheros wireless chipsets are being used by a number of companies, including personal computer and networking equipment manufacturers.
What is 802.11g?
IEEE 802.11g is a wireless networking standard that operates over relatively short distances at up to 54 megabits per second (Mbps). It is significantly faster than 802.11b, which transfers data at a maximum of 11 Mbps. 802.11g is backwards compatible with the earlier standard and both are frequently referred to with the term “Wi-Fi”.
