PicoCELA was born as a Kyushu University venture and has cultivated stable wireless mesh technology that serves the enterprise market for 15 years. The PicoCELA Backhaul Engine (PBE), backed by dozens of inventions, has a unique dynamic tree routing technology at its core, and is capable of stable mesh routing even in large mesh structures with mesh cluster sizes of more than 10. The system provides stable backhaul communication.
Wide-area Wi-Fi networks formed by PBE have been installed in an estimated 1,000 locations in Japan. In most of these installations, the amount of LAN cable wiring has been reduced by more than 70%. For example, in an underground shopping mall in Fukuoka City, 27 PicoCELA devices cover a continuous free Wi-Fi space of 1.2 km in total length, using only 4 LAN cables. The wireless mesh system has been in operation for more than 10 years and is one of the largest free Wi-Fi systems in Japan, with more than 1.8 million users per year. The first is a "one-stop shop" for the entire city of New York. In addition, the technology for building highly mobile and stable wireless networks has been highly evaluated and is widely used as the No. 1 Wi-Fi solution in the building and civil engineering market.
PicoCELA's advanced wireless technology and phenomenal growth have been highly acclaimed in many fields. Japan's Ministry of Land, Infrastructure, Transport, and Tourism operates NETIS (New Technology Information System) as a core system to promote the use of new technologies in public works projects, etc. PicoCELA was the first wireless mesh device to be registered as a recommended product. In 2019, PicoCELA was selected as one of the NEXT Unicorn 100 by Nihon Keizai Shimbun, and in 2021, PicoCELA was selected as one of the The company was selected by the Financial Times as one of the High-Growth Companies Asia-Pacific 2021. The company's commitment to intellectual property has also been recognized, and in 2019, the Japan Patent Attorneys Association honored the company as the first recipient of the Intellectual Property Utilization Incentive Award.
Although we have been developing our business mainly in Japan, we are now aiming to expand into the global market, expanding our product lineup, diversifying our solutions, and strengthening our organizational structure.
