The Atheros AR9285 single-chip PCI Express® solution features Atheros Align technology, which leverages the 802.11n 1–stream specification to provide the optimal upgrade path from legacy 802.11 solutions. The single-stream feature enables a new class of Wi-Fi devices that deliver performance enhancements over the existing 802.11g technology, at comparable price points. Align® solutions are forward compatible to higher-performance, multi-stream, MIMO–based 802.11n, and are available in reference designs to serve the networking, computing and consumer electronics markets. The enhanced throughput of Align 1–stream solutions improves network efficiency by occupying the wireless channel for shorter periods than slower 11g devices – reducing congestion and increasing capacity for additional wireless devices. Align employs all the mandatory and select optional features of the 11n specification, and Atheros’ advanced radio design techniques, to effectively double the wireless coverage over legacy WLAN.
