APPLE AirPort Extreme Atheros AR5BXB112

Description

AR9380 is the single-chip, dual-band (2.4/5 GHz), 3-stream 11n solution with PCIe interface.
It packs the breakthrough Signal Sustain Technology 3 (SST3) technology that enhances the rate-over-range (RoR) performance.
SST3 is a set of advanced technologies and features enabled by 802.11n including LDPC, TxBF and MLD. The end result is an impressive increase in rate-over-range of ~+100% at short range, ~+50% at mid range and ~+25% at long range.
AR9380 is also optimized for P2P applications compliant with Wi-Fi Direct.
TM With its Fast Channel Switch (FCS) feature, the channel switching time between 2.4 GHz and 5 GHz is reduced from 10 ms to as little as 1 ms.
