Product Description

The MT7981A is engineered to handle the demands of high-speed and high-efficiency networking. Supporting Wi-Fi 6, it delivers enhanced wireless performance by leveraging the latest technologies such as OFDMA, which enables the sharing of bandwidth between devices more efficiently. MU-MIMO allows for simultaneous communication with multiple devices, ensuring that devices in crowded environments (such as homes with many connected smart devices) can maintain fast and stable connections.

The MT7981A’s multi-gigabit Ethernet support ensures that high-speed wired connections can be maintained, even in demanding setups. This feature is ideal for users who require top-tier performance for tasks like 4K streaming, online gaming, and large file transfers. By supporting Ethernet speeds up to 10 Gbps, it is suitable for high-performance environments such as enterprise networking and advanced home setups.

In addition to its impressive networking capabilities, the MT7981A includes an NPU for optimized network traffic management. This allows for real-time adjustments to traffic distribution, reducing latency and improving the overall network experience. Whether for gaming, high-definition media streaming, or enterprise-level networking, the NPU ensures efficient handling of multiple data streams simultaneously.

Security is a priority with the MT7981A, which includes WPA3 encryption for stronger protection against unauthorized access, ensuring that network data is kept secure even in high-risk environments. It also integrates advanced hardware security features to protect against potential cyber threats.

Despite its high-performance features, the MT7981A is optimized for power efficiency, which helps reduce operational costs and extends the lifespan of devices using this SoC. The 28nm fabrication process plays a key role in ensuring that power consumption remains low, even when the device is operating at full capacity.
