Achiever Big Data provides location analysis solutions that lay the foundation for smart city in the areas of retail, food and beverage, industry 4.0, healthcare, transport and smart community. During the participation of The Daya Bay Reactor Neutrino Experiment, Dr. Jack Tam (CEO) and Dr. Jimmy Ngai (CTO) were inspired by the process of analyzing particles movement and established an artificial intelligence indoor positioning algorithm which can be applied to humans and assets. By detecting signals from mobile phones or other mobile devices, this algorithm will increase the accuracy of positioning analysis from 4 meters to 1 meter compared to the market. In the field of healthcare, Achiever Big Data provides users with accurate and real-time location tracking and analysis.
