LoRa, which stands for Long Range, is a wireless communication technology that allows for transmitting low-power signals over a long distance while maintaining low data rates. It is specifically designed for the Internet of Things (IoT) applications, where low-power consumption and long-range transmission are crucial.
LoRaWAN is a protocol that uses the LoRa technology for communication between IoT devices and gateways. LoRaWAN provides a long-range wireless network that connects IoT devices to the internet.
LoRa technology was developed by a French company called Cycleo, which was later acquired by Semtech Corporation in 2012. LoRaWAN was developed by the LoRa Alliance, which is an open, non-profit association that aims to standardize the LoRa technology and promote its use for IoT applications.
Importance of LoRaWAN in IoT devices
LoRaWAN is an essential technology for IoT devices, providing long-range, low-power communication between devices and gateways. IoT devices are often located in remote areas where traditional wireless technologies like Wi-Fi and cellular networks are not feasible due to their high power consumption and limited range. LoRaWAN provides a low-cost and low-power solution for connecting IoT devices to the internet.
How LoRa gateways work
LoRaWAN gateways act as a bridge between the IoT devices and the internet. They receive data from the devices and transmit it to a network server, which then forwards it to the application server. The application server then processes the data and sends back commands to the IoT devices via the network and gateway.
LoRaWAN is used in various applications ranging from agriculture to healthcare. Below are listed some of the prevalent use cases for LoRaWAN technology:
Agriculture and farming
LoRaWAN is used in agriculture and farming to monitor soil moisture, temperature, and other environmental parameters. It helps farmers to optimize water usage, prevent crop damage, and increase yield.
