• Communications

BLE (Bluetooth Low Energy) is excellent for low power consumption and short-range communication, and it has become widely used for tracking the location of patients and medical devices and for data collection within medical facilities. However, BLE has a short communication range of about 10 meters, which poses limitations for extensive communication and data transmission across multiple floors within buildings. To overcome this limitation, we aim to build a broader communication network by combining it with LoRa (Long Range) communication.
