Supported by CompexWRT (v3.x and above) with Qualcomm Atheros reference wireless drivers. Throughput up to 800Mbps on WPJ558, WPJ563, and WPJ564 platforms; up to 1300Mbps on WPQ864 and WPQ865. Also supports OpenWRT/LEDE with ath10k wireless drivers.
Yes, WLE1216V5-20 supports 4×4 MU-MIMO (Multi-User MIMO), allowing it to communicate with multiple clients simultaneously, improving throughput in high-density environments.
80+80MHz (also called 160MHz equivalent) is a channel bonding technique that combines two non-contiguous 80MHz channels to achieve higher data rates up to 1733Mbps.
Dynamic Frequency Selection (DFS) is a regulatory requirement that allows WiFi devices to detect and avoid radar signals in certain 5GHz channels. This provides access to additional channels that are otherwise restricted, increasing available spectrum.
The heat sink is integrated into the module and requires no special mounting. It enables free air operation, simplifying system integration and reducing cooling requirements.
