What is LoRaWAN Protocol in IoT - Working and Applications

Table of Contents [show]

LoRaWAN protocol in IoT is a technology that helps connect devices to the internet without using wires. It’s designed to work with devices with batteries and must stay connected over long distances. In other words, it is a wireless network for small things, like sensors or trackers. It's secure, allows two-way communication, and can even track the location of devices.

What is LoRaWAN Protocol in IoT?

LoRa is a unique way of sending radio signals that helps devices communicate over long distances. It’s like a secret code that makes the signals stronger and harder to interfere with. In addition, “LoRa” can also mean the devices that use this technology or the network that connects them.
 

LoRaWAN in IoT is a set of rules devices follow to communicate using LoRa technology. Multiple versions of these rules are there, and they can vary depending on where the devices are used. You can find more information about these rules and how they differ by region on the LoRa Alliance website. The most common version is 1.0.x, which includes versions 1.0.1 to 1.0.4.
 

IoT LoRaWAN is a widely accepted way for devices to connect to the internet using radio waves. It's designed to work with devices with batteries and must stay connected over long distances. Moreover, anyone can create a LoRa network, and the technology uses radio waves that are available for everyone to use, without needing an advanced license. LoRa is a way of sending radio signals that makes them strong and resistant to interference, but it can only send a small amount of data at once.

• Saving Water: Sensors can help cities find and fix leaks in their water pipes.
• Ensuring Food Safety: Sensors can ensure food is kept at the right temperature.
• Managing Waste: Sensors can help cities manage their waste by letting them know when trash cans are full.
• Tracking Bikes: Tracking devices can help people find their bikes if they are stolen.
• Improving Airports: Sensors can help airports track vehicles, people, and luggage.
• Making Workplaces Better: The LoRaWAN IoT sensors can help in tracking room occupancy, temperature, energy use, humidity, and parking availability.
• Monitoring Cattle Health: Sensors can help farmers monitor the health of their cattle and predict when cows will give birth.
• Providing Global Coverage: We can use LoRaWAN protocol in IoT for space tasks to provide coverage all over the world.

As you can see, LoRaWAN is a versatile technology with many potential applications.

LoRaWAN Architecture in IoT

We all know LoRaWAN is a wireless technology that can be used to send data over long distances, even through walls and other obstacles. It's perfect for places like farms, cities, and buildings.
 

1. Range and Coverage: LoRaWAN can cover a large area, even miles. A single LoRaWAN antenna can cover thousands of square meters, making it great for buildings.
2. Signal Adaptability: LoRaWAN can adjust its signal strength to improve range while saving energy.
3. Flexible Spreading Factor: The IoT Lora network can adjust its spreading factor to work well in different environments.
4. Energy Efficiency: LoRaWAN devices can last for up to ten years on a single battery.
5. Different Sensor Classes: LoRaWAN has different sensor classes that balance energy use and communication.
6. Latency and Data Rate: LoRaWAN's latency is a bit higher than cellular networks, but it's still good enough for most IoT applications. In addition, it can transmit small amounts of data, which is perfect for IoT devices.

Overall, LoRaWAN is a great choice for IoT applications that require long-range, low-power communication.
