Abstract
Since the establishment of the ERi corporation we have been developing business using wireless communication technology utilizing Bluetooth. As a result of focusing on commercialization based on original ideas of the company, in 2012, we successfully commercialized the world's first Bluetooth beacon transmitter for smartphones "BLUETUS (R)". We are currently working on the research and development of indoor position estimation system "BLEGONIO" as a product development of BLUETUS. In research and development, we are actively collaborating with neighboring universities. We introduce the development of these two products.
