1. Introduction to Social Distance Watch
1.1 Introduction
System is a set of ranging system based on Ultra-Wideband Technology, which
has the characteristics of high precision, large capacity, strong multi-path resistance
and low power consumption.
Watches worn on the person consistently monitor the distance to the
surrounding watches. When the distance is less than the safe value, an alarm signal
will be generated immediately. The sound and light alarm reminds to prevent the
person from being too close and reduce the risk of virus spreading.
