Product Description
The MediaTek MT7921AUN is a high-performance Wi-Fi 6E and Bluetooth 5.2 M.2 module designed for devices requiring advanced wireless connectivity. Key features include support for IEEE 802.11 a/b/g/n/ac/ax/axe standards, offering dual-band support on the 2.4 GHz, 5 GHz, and 6 GHz bands. The chipset is capable of reaching data rates of up to 1201 Mbps on Wi-Fi 6 (802.11ax) and supports Bluetooth 5.2 with BLE for efficient low-energy communication.
It integrates advanced technologies like beamforming (both TX and RX), Low-Density Parity-Check (LDPC) coding, and Space-Time Block Coding (STBC), which enhance signal strength and performance, especially in environments with interference. The module supports dual-mode Bluetooth, allowing simultaneous operation of Wi-Fi and Bluetooth, optimizing both data throughput and power efficiency.
In terms of power efficiency, the MT7921AUN is designed with a low power consumption profile. It operates with a maximum current of 755 mA at 3.3 V, making it suitable for devices where energy efficiency is crucial. This module is primarily targeted at IT departments or corporate use, as it is embedded within devices like laptops, routers, and desktops. It does not come with end-user installation instructions, so professional installation is typically required.
