WiFi 6/6E + Bluetooth BT/BLE v5.2 LGA Module (MT7921AUN)
AMLGA7921 is a highly integrated module that features a high-performance 2×2 Tri-band WLAN subsystem and Bluetooth v5.2 subsystem. 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, costeffective 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.
