Description
The Atheros AR9220 is a highly integrated single-chip solution for 2.4 and 5 GHz 802.11nready wireless local area networks (WLANs) that enables high-performance 2x2 MIMO configurations for wireless station applications demanding robust link quality and maximum throughput and range.
Features
- include signal detection, automatic gain control, frequency offset estimation, symbol timing, and channel estimation. The AR9220 MAC supports the 802.11 wireless MAC protocol, 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS). The AR9220 supports two simultaneous traffic streams using up to two integrated transmit chains and receive chains for high throughput and range performance. Transmit chains combine baseband in-phase (I) and quadrature (Q) signa.
