威胜信息Wi-SUN通信组网技术获美国专利授权Willfar’s Wi-SUN net gets U.S. Pat

Recently, the "core technology for IoT wireless communication" independently developed by Willfar Information has officially obtained authorization from the U.S. Patent and Trademark Office (USPTO). This marks another breakthrough following its two previous international patents, signifying that the company’s technological innovation capabilities in the field of energy IoT have been recognized by the world’s top intellectual property authorities, and also laying a key foundation for the company’s core IoT technologies to enter the international market.

Where Does IoT Communication "Congest"? Traditional Technologies Face Challenges

Wireless communication serves as the "neural network" of the Internet of Things (IoT). As a key technology in IoT, frequency-hopping communication leverages the feature of "wide-band frequency hopping" to effectively avoid wireless interference, making it widely used in scenarios such as smart grids, smart parks, and industrial IoT.

However, traditional frequency-hopping communication has a critical weakness: the entire network relies on a single unified frequency-hopping sequence, requiring all nodes to "synchronize" to the same frequency for communication. This is analogous to a single-lane road, where all vehicles try to pass at the same time and in the same lane—easily leading to multi-node "lane-jumping" conflicts. Such conflicts cause data packet loss and a sharp drop in transmission efficiency, seriously undermining the stable operation of large-scale IoT networks.

Willfar’s "Asynchronous Frequency Hopping" Breaks the Deadlock, Significantly Boosting Channel Efficiency

To address this industry challenge, Willfar Information has developed an independent solution: the Wi-SUN-based asynchronous frequency-hopping networking communication method for wireless IoT.

Unlike the traditional "synchronized frequency crowding" model, this patented technology adopts an "asynchronous frequency hopping" design: it eliminates the need for all nodes to be forced to synchronize to the same frequency. Instead, different nodes can flexibly select communication frequencies based on network conditions, fundamentally reducing conflicts caused by "multiple nodes competing for the same channel."

To put it vividly, this is equivalent to transforming a "single-lane road" into a "multi-lane intelligent dispatching system"—each device can find an "uncongested" frequency for data transmission. This not only resolves the issue of data packet loss but also significantly improves channel utilization efficiency, providing core technical support for the stable operation of large-scale IoT networks (such as million-level smart meter networks and large-scale smart energy monitoring networks).

Three International Patents: Sustained Innovation to Empower Global IoT

As a pioneer in China's energy Internet of Things (IoT) sector and Hunan's first company listed on the Sci-Tech Innovation Board (STAR Market), Willfar Information has always taken "Connect the IoT World, Link the Core to the Future" as its strategic core, with technological innovation serving as the key driver for its global development. As of now, Willfar Information has accumulated three international patents, all focusing on key industry fields such as IoT communication and energy data transmission—each precisely addressing critical industry challenges. These technological achievements not only build a solid "technological moat" for the company's global business but also export "Chinese solutions" in the IoT field to the world. They help the global energy IoT industry break through technological bottlenecks and accelerate green, low-carbon, and digital transformation.

Looking ahead, Willfar Information will continue to deepen its focus on core energy IoT technologies. Based on its international patent layout, the company will further expand global technological cooperation and market share, drive efficiency improvements in the IoT industry through technological innovation, and contribute more to the realization of the "dual carbon" goals and the global digital transformation of energy.
