Since 2016, the State Grid and China Southern Power Grid have begun to accelerate the construction of smart grids, broadband power carrier technology as the main communication transmission mode of power grid intelligence, has been widely used; at the same time, the rapid development of the Internet of Things requires the access of massive terminal equipment to the Internet, broadband power carrier technology can provide reliable, safe and efficient communication network.
Broadband power carrier communication to the existing power line as the carrier to transmit network information, the transmission distance can reach several kilometers, no need to build additional network, the network with the power, will form a new generation of intelligent communication network. In the era of Internet of Everything, broadband power carrier communication technology is one of the most effective communication access methods, ensuring the last mile of Internet of Things communication.
▲Based on broadband power carrier technology to achieve the information transmission of electrical equipment, broadband power line carrier communication chip is the core device to achieve carrier communication
It is based on the huge development prospects of broadband power carrier communication technology in the field of Internet of Things, as well as the huge business ecology generated in the process of the integration and development of the Internet of Things and smart grids, in 2016, wuqi aimed the first chip developed at the beginning of its establishment aimed at broadband power carrier communication, formed a world-class chip research and development team, and successfully developed the first high-performance broadband power carrier communication chip WQ3011 in just over a year.
The successful development of the first broadband power carrier communication chip is of landmark significance to the development of Wuqi and is the most critical step for the company to successfully move towards the field of Internet of Things communication.

Once this chip was released at the end of 2017, it relied on its strong performance and on-site networking stability to achieve shipments of nearly one million units in a short period of time. With the in-depth development of the Internet of Things, broadband power carrier communication applications are also constantly expanding new scenarios, Wuqi WQ3011 broadband power carrier chip from the initial smart grid collection application, the development of the Internet of Things smart home, smart street lights, building energy consumption management, smart photovoltaic and other scenarios to provide convenient communication transmission, to achieve stable access and automatic control.
The smart home solution based on Wuqi chip launched by our industry customers has received a warm response in the market, which integrates broadband power carrier communication technology into various household appliances, and uses the existing power line of the home as a carrier communication medium, and the network is connected with Dentsu, thereby realizing communication and control between smart devices. Through the transmission of communication networks, the interconnection and interaction between smart electrical appliances build a real smart life scene, and you can enjoy the comfort and convenience brought by smart technology.

In addition, with the country vigorously promoting the "double carbon" goal and accelerating the construction of new energy, energy conservation and development of renewable energy have become important measures. Industry customers in related fields have designed a number of mature energy solutions with Wuqi's broadband power line carrier chips. For example, in the intelligent building energy consumption management project, our customers collect the energy consumption information of all electrical equipment through power line communication to achieve intelligent management and control of energy consumption; in the field of photovoltaic power generation, our customers have configured maximum power tracking technology (MPPT) and shutdown control device (RSD) for each panel through software and hardware cooperation, which increases the safety factor of photovoltaic power plants, and greatly improves the power generation efficiency of power stations, directly and greatly improving the efficiency of new energy utilization.
After years of development, Wuqi's first broadband power carrier communication chip has achieved annual shipments of tens of millions of pieces, widely used in the field of Internet of Things communication, and achieved good economic and social benefits. At present, the company has launched a powerful edge computing chip WQ3021, and will also launch a broadband power carrier communication chip WQ3031 with more outstanding performance, continuing to exert efforts in the AIoT market and embracing the tide of the Internet of Things era. Wuqi broadband power carrier communication chip research and development layout science, application scenarios continue to enrich, the market coverage is also growing rapidly, we believe that "the singularity of the Internet of Things has arrived, will bring about the rapid progress of the semiconductor industry."
