Kiana’s real-time digital contact tracing containment system uses device-based detection and location-based analytics to help stop the spread of the COVID-19. Leverages existing Wi-Fi infrastructure, so no new equipment nor app or software needs to be installed. Combines information of an employee testing positive for COVID-19 and their location via the office Wi-Fi. Warns those employees who have been in close proximity with the infected person. Also uses data to re-engineer your facility and foster well-being post COVID-19.
