The AWM27921U is a high-performance 2x2 dual-band WLAN and Bluetooth v5.2 M.2 module.
The WLAN subsystem contains the 802.11a/b/g/n/ac/ax radio, a baseband designed to meet feature-rich wireless connectivity at high standards, and deliver reliable, cost-effective throughput from an extended distance.
Optimized RF architecture and baseband algorithms provide superb performance and low power consumption. Intelligent MAC design deploys a highly efficient offload engine and hardware data processing accelerators which fully offloads WiFi task of the host processor.
