LW004 series is a LoRaWAN-Based network IoT button specifically designed for contact tracing purposes. It is compact, small in size and easy to use. This smart gadget has the capability to scan the incoming data from nearby BLE beacons. So, it then sends this data to the nearest LoRaWAN gateway. Hence, the LoRaWAN gateway then transmits this data over to the cloud server. Once this data reaches the cloud, it is accessible from all over the world 24/7.
It is a relatively old term but has gained popularity in recent times. Indoor GPS tracking wearables can scan Bluetooth beacons which installed in the workplace and map safe zones. So, we can utilize indoor GPS tracking for disinfecting contaminated areas. Indoor GPS tracking is a very important technology when it comes to battling the COVID-19.
I hope these programs can help you.
