Background - Covid-19 pandemic has forced countries to adopt contact tracing comprehensively in order to restrain the highly infectious virus from further advancement. In this case, Bluetooth Low Energy (BLE) has been widely used utilizing Received Signal Strength Indicator (RSSI) for Close Contact Identification (CCI). Nevertheless, big portion of the available solutions are not able to follow to the rules provided by Centers for Disease Control (CDC) and Prevention which are: (1) Distance requirement of within 6-feet (~2 meters) and (2) Duration of no less than 15-minutes for CCI. Purpose - The purpose of the research is to develop and test a new approach on contact tracing for Covid19 using low calibrated transmission power and signal scans in Bluetooth Low Energy (BLE). Design/methodology/approach - The new approach is to lowly calibrate Tx so that when distance is at 2 meters between users, number signal capture gets lower as the chipset’s smallest RSSI value sensitivity has been realized. In this study, complete experimentation for Proof of Concept (POC) and Pilot test conducted are demonstrated. Findings/Expected Contributions - Results collected shows that the accuracy for POC utilizing signal captures for 20.3m length is at: (1) 71.43% for 5 users and (2) 70.69% for 9 users. While so, accuracy for the Pilot test when taking account of CCI on individual case-basis is at 95% for 5 users. Research limitations - One of the main limitations is to add a bigger number of devices for the POC and Pilot test in order to find out more insights on this new approach for bigger number of users. Originality/value - The approach is new that none of the contact tracing solutions has adopted the method for Covid-19 pandemic. It is scalable as it is in advertising mode in which more than 20 users can be in vicinity, eliminates the setbacks of RSSI as it does not rely on RSSI and eliminates the disadvantages of venue-based tracing.
