Product Description

The MT6922A is designed to address the growing need for high-speed, reliable, and energy-efficient wireless connectivity in a variety of applications. Here’s a more detailed look at its features and benefits:

  • Wi-Fi 5 (802.11ac) for High-Speed Performance:

    • The MT6922A supports Wi-Fi 5 (802.11ac), which is ideal for applications requiring high data throughput, such as HD video streaming, cloud gaming, and large file transfers. With a maximum theoretical speed of 1.3 Gbps on the 5 GHz band, the chip ensures fast and stable wireless performance for devices that need to process high-bandwidth content.

  • Dual-Band Operation for Flexibility:

    • By supporting dual-band Wi-Fi (2.4 GHz and 5 GHz), the MT6922A offers a flexible solution for devices operating in varying environments. The 2.4 GHz band offers broader coverage, ideal for longer-range communication, while the 5 GHz band provides higher data rates and less interference, making it suitable for environments with many competing wireless signals.

  • Bluetooth 5.0 for Extended Connectivity:

    • The MT6922A integrates Bluetooth 5.0 technology, allowing devices to communicate with a wide range of Bluetooth-enabled products. With a longer range of up to 240 meters and improved data transfer rates (up to 2 Mbps), Bluetooth 5.0 ensures reliable connectivity, even over larger distances. This makes it ideal for applications such as asset tracking, smart home automation, wearables, and wireless peripherals like speakers and headphones.

  • Energy Efficiency for IoT Devices:

    • One of the key features of the MT6922A is its low power consumption, which is particularly important for IoT devices and other battery-operated products. The chip includes several energy-saving features, including Dynamic Voltage Scaling and Idle Power Saving, to help devices operate for extended periods without frequent recharging. This is especially beneficial for devices that need to remain connected to networks for long durations, such as smart sensors and environmental monitoring systems.

  • Enhanced Security for Protected Communication:

    • The MT6922A supports WPA3 encryption, the latest Wi-Fi security protocol, providing stronger protection against unauthorized access to Wi-Fi networks. This ensures that sensitive data transmitted over wireless networks is encrypted and protected from potential breaches. Additionally, the chip includes hardware-based encryption to safeguard the transmission of data, especially in applications where privacy is a top concern, such as healthcare and financial services.

  • Compact and Cost-Effective Design:

    • The MT6922A’s highly integrated design combines Wi-Fi and Bluetooth functionalities into a single chip, reducing the need for multiple separate components. This compact design simplifies the product development process and reduces the overall cost of manufacturing, making the MT6922A an attractive choice for companies designing cost-effective consumer electronics, smart home devices, and IoT products.
