Qingdao Siflower Communication Technology Co., Ltd. was founded in 2014. The founder of the company, Dr. Xingren Li, led the team to successfully develop the first BeiDou II satellite navigation chip and the first CPU chip for tablet PCs in China. Since its inception, the company has been focusing on the research and development of WiFi routing communication chip, which is a gap in China's industry chain, with the mission of "import substitution, independent control and information security". After four and a half years of arduous exploration and over 100 million RMB investment, the company successfully mass-produced SF16A1890, the first wireless WiFi routing chip in China, at the end of the first quarter of 2018, which integrates WiFi 2.4GHz and 5GHz dual-band and one-core, with a maximum wireless connection speed of 600Mbps (megabits per second), and its successful mass production marks the first time that China's industry chain has achieved a WiFi routing chip independently controllable new breakthrough.

At the same time, the company continues to innovate and climb to the top in research and development. On the basis of the follow-up solution development of A18 chip, the company has put into the research and development of next generation WiFi routing chip non-stop. In September this year, we successfully streamed the SF19A28, the first domestic one-core dual-band gigabit WiFi routing chip, which retains the high integration of SF16A18 chip and improves the double bandwidth with the highest connection speed of 1200Mbps (megabits per second) and supports MIMO2*2 dual-channel communication.

The team chose the "difficult first, then easy" technology breakthrough route. Five years of hard work and the successful development of two chips have laid a solid technical foundation for SiS to become the leader in WiFi communication in China, and to prepare for the development of multiple product lines later. In the next five years, SiS will give full play to its core competencies and extend downward from WiFi technology to cover more WiFi application scenarios and integrate more product functions. We will strive to become the top chip designer in China with WiFi communication as the core, serving IoT, artificial intelligence, edge computing and other fields.
