Social Distance Alert System to Control Virus Spread using UWB RTLS in Corporate Environments

Abstract

Recent pandemic situation of covid-19 which is caused due to the outbreak of highly dangerous and easily spreadable corona virus is an increasing concern throughout the entire world. The purpose of this study is to develop an alert system which alerts employees to maintain social distance in corporate working environments. A real-time location systems (RTLS) based on ultra wide band (UWB) wireless technology gives most accurate locations of approximately 10cm using methods like trilateration and TDOA (Time Difference of Arrival). Co-ordinates of the location can be obtained by installing RTLS in predefined area which are used to calculate the distance between Mobile UWB Devices (MUD's). An alert triggered by a system to maintain distance if distance between the employees is less than the prescribed social distance can keep the work premises safe and control the spread of corona virus. This study can be a great solution to control spread of virus in corporate working environments which are mostly of confined in size and indoor in nature.
