LoRa (Long Range) and LoRaWAN Technology for IoT Applications in COVID-19 Pandemic

LoRa (Short for Long Range) is the fastest growing technology attracting researcher's interest now a days. Long battery life, long distance communication and low cost application specific devices are main focus of the engineers, LoRa is quite suitable for these requirements. IoT system includes four explicit sections for example sensors/devices, connectivity, processing of information and a user interface. The scope of communication has become the basic part on the majority of the IoT system, particularly in Wi-Fi and Bluetooth based IoT system. With the rise of LoRa technology, further enhancements to uses of the Internet of Things (loT) can be figured it out. By utilizing a single receiver in the LoRa network, it can deal with numerous hubs at various areas inside the region, dissimilar to Wi-Fi-based framework which needs to have many access point to cover large area. Both LoRa and Wi-Fi innovation has reduced total cost of IoT framework. For the wide range coverage of IoT system, LoRa is quite useful as compared to Wi-Fi and Bluetooth for short range. However, there are a few inconveniences on the speed of transmission and constraint on the size of the payload. The world when struggling with the COVID-19 pandemic, LoRa devices and the LoRa Wanprotocol are playing an instrumental role in enabling public safety solutions to assist with contact tracing, ensuring healthcare regulation compliance in the workplace and addressing the needs of medical professionals. This paper presents a specialized work on LoRa/LoRa W Aninnovation for IoT applications.
