Mitsubishi Electric – Wireless Localization for Contact Tracing

  • by

Providing technologies that localize occupants of a building will be needed for effective contract tracing as societies try to manage and contain the spread of COVID-19. Indoor localization methods that do not require the use of GPS but rather depend on existing communication networks offer a way to rapidly deploy technologies to aid in managing the number of occupants in a building, ensure social distance guidelines are being observed and allow detailed contact tracing. These technologies can operate over a range of wireless technologies including WiFi, UWB and IoT networks.
