About the company
PicoCELA has been developing stable wireless mesh technology for the enterprise market for nearly 20 years. The PicoCELA Backhaul Engine (PBE), backed by dozens of inventions, is based on a unique dynamic tree routing technology that enables stable backhaul communication even in large mesh structures with mesh cluster sizes exceeding 10.
Wide-area Wi-Fi networks formed by PBE have been installed in an estimated 1,000 locations in Japan to date. 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 total of 1.2km of continuous free Wi-Fi space with only 4 LAN cables. The wireless mesh system has been in operation for more than 10 years with more than 1.8 million users per year. It can be said to be one of the largest free Wi-Fi systems in Japan. The system is widely used as the No. 1 Wi-Fi solution in the construction and civil engineering market because of its ability to create a stable wireless network in a swift manner.
PicoCELA's advanced wireless technology and remarkable growth have earned the company a high reputation in many fields. Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) operates the NETIS (New Technology Information System) as a core system to promote the use of new technologies in public works. PicoCELA is the first wireless mesh device to be registered as a recommended product. PicoCELA was also
selected as one of the NEXT Unicorn 100 by Nikkei Inc. in 2019 and as one of the High-Growth Companies Asia-Pacific 2021 by the Financial Times in 2021. We have also been recognized for our efforts in intellectual property, and in 2019, the Japan Patent Attorneys Association awarded us with the first-ever Intellectual Property Utilization Encouragement Award.
We have been developing our business mainly in Japan, but we are now taking actions such as expanding our product lineup, diversifying our solutions, and strengthening our organizations with the aim of expanding into the global market.
