Atheros Ar9285 Datasheet [upd] ✮

Despite being technologically obsolete, the AR9285 finds new life in niche applications:

The is a highly integrated single-chip PCI Express (PCIe) solution designed for 802.11n wireless networking. It belongs to the "Align" technology family, which uses a 1-stream (1x1) specification to provide an affordable upgrade path from legacy 802.11g devices. Technical Specifications Standards : IEEE 802.11b/g and 802.11n (1-stream). Frequency Band : 2.4 GHz only (does not support 5 GHz). Maximum Data Rate : Up to 150 Mbps PHY rate. Interface : PCI Express 1.1 compliant. Channel Bandwidth : Supports 20 MHz and 40 MHz. Hardware Security : AES, TKIP, and WEP. Atheros Ar9285 Datasheet
