PCIe for WLAN and USB for BT
Single-chip 55nm, 802.11a/b/g/n 2.4/5 GHz, 2-stream  w/ SST Technology
 and Bluetooth 4.0 + HS + BLE
2011ish https://deviwiki.com/files/Atheros/specsheets/AR9462.pdf
Conserves power with 1x1 downshift, using Dynamic MIMO Power Save
Supports Atheros’ Signal-Sustain Technology™ (SST).
Advanced SST features include:
Low Density Parity Checking (LDPC),
Transmit Beam Forming (TxBF),
Maximum Ratio Combining (MRC),
and Maximum Likelihood Demodulation (MLD)
which together can increase rate-over-range performance by 
up to 100% at short range, 50% at mid-range and 25% at long range.

Requires a WiFi firmware called “ART” (Atheros Radio Test). It holds device specific wireless calibration data, thus using a generic or the wrong firmware causes FCC incompliance and poor wireless performance.
Usually the firmware is stored in an ART partition located at the last 64KiB of the flash. If the ART partition is missing or corrupt, ath9k (wireless driver) won't come up anymore.
