Qualcomm Atheros QCA 9377 dual-band WiFi AC Bluetooth wireless network card

Advanced 802.11ac combo SoC - This module is EOL - you can use Intel AC7265 module instead

Advanced 802.11ac features such as MU-MIMO, Host wake-on-wireless and ARP (Address Resolution Protocol) offloading enable the WLAN link to remain associated for extended periods for additional power savings

Supports dual-mode Bluetooth 5  - QCA9377 supports Bluetooth for Class-1 and Class-2 transmissions without requiring an external power amplifier Advanced WLAN/Bluetooth coexistence and concurrent RX WLAN/Bluetooth coexistence allows for superior rateover-range throughput and low-latency performance in real-world operating conditions Power saving techniques for low power consumption

Both WLAN and Bluetooth power management utilize advanced power saving techniques such as: - gating clocks to idle or inactive blocks - voltage scaling - fast start and settling circuits - active duty cycles - processor frequency scaling
