Qualcomm Atheros AR9287 AR5B197 FOR IBM Lenovo Half Mini PCIe WLAN WIFI BT BlueTooth Card

AR9287 Highly integrated single-chip PCIe
             with 2-stream 802.11n support

The Atheros AR9287 is the single-chip, single-band 2.4 GHz solution for PCIe in XSPAN’s fourth generation of products. The AR9287 Half-Mini Card is the most integrated and compact 802.11n solution for 2-stream with nearly 20% fewer components than the previous generation single-band PCIe on the market, enabling mainstream computing market applications.
It offers the optimal balance of performance, power and price with its single-band, 2×2 MIMO configuration, which features downshift to 1×1 MIMO with Dynamic MIMO Power Save. The AR9287 follows in Atheros’
drive towards integration ?and is the eleventh single-chip client solution to be introduced.
