Description
The Atheros AR9223 is a highly integrated single-chip solution for 2.4 GHz 802.11n-ready 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 AR9223 MAC supports the 802.11 wireless MAC protocol, 802.11i security, receive and transmit filtering, error recovery, and quality of service (QoS). The AR9223 supports frame data transfer to and from the host using a PCI interface that provides interrupt generation and reporting, power save, and status reporting. Other external interfaces include serial EEPROM and GPIOs. Th.
