Social Distancing

Embedded Software Applications for Social Distancing Applications

Renesas provides leading-edge software references for distance measurements between Bluetooth^® devices. In the COVID-19 pandemic context, this technology can be used for alerting people in keeping a safe social distance to other people. Two different projects are provided as described below.

Accurate measurements based on Renesas' Wireless Ranging (WiRa) technology

WiRa uses a radar-like implementation to greatly enhance distance measurement for connected devices, amounting to +/- 0.5 meters in typical situations. The provided software example runs on the DA1469x family of Bluetooth devices and has been created on top of the SmartBond™ Wireless Ranging SDK.

Distance measurements based on Received Signal Strength Indication (RSSI)

Distance measurements based on RSSI allow for implementation on any Bluetooth-enabled devices. The results are not as accurate as WiRa but it will run on low-end devices and therefore can be created at a lower cost. The provided software example demonstrates the functionality on the DA14531 IC and also on the DA14531 TINY™ Module
