What is LoRaWAN?

HubSpot Video

LoRaWAN (Long Range Wide Area Network) is a communication protocol designed for Internet of Things (IoT) devices. In Therma’s case, IoT refers to a system of devices (sensors) that measure temperature and humidity and transfer the results to the customer without needing any human interaction.   

These temperature sensors can communicate with users and each other over long distances. The LoRaWAN technology uses a wireless standard called Long-Range Radio (LoRa) and is designed to work in both urban and rural environments.

Why is LoRaWAN Useful?

LoRaWAN is a low-cost and low-power solution for IoT devices to communicate with the cloud. Devices using LoRaWAN only send small amounts of data at once, incurring very small data costs and making the devices very power efficient. This means that LoRaWAN devices can be powered by and last 10 to 15 years on a single battery, allowing them to be small and convenient to  install in difficult to reach locations.

As implied by its name, LoRaWAN’s communication capabilities span very  long range distances. For its world record, LoRaWAN was recorded to stay connected for up to 476 miles. Its long range connectivity allows IoT devices to communicate over distances that Bluetooth (BLE) and Wi-Fi are unable to maintain. While not a world record holder, Therma° LoRaWAN devices still maintain an impressive average connection distance of around 1200 feet. 

In addition, LoRaWAN signals can penetrate dense materials better than BLE and Wi-Fi, making it the most suitable form of connection from inside refrigerators and behind thick walls. It is this exact capability that makes Therma° devices industry leaders in refrigeration monitoring connectivity reliability. 

Finally, LoRaWAN also supports a large number of connected devices, making it possible to connect thousands of IoT devices to the network without worrying about bandwidth or devices dropping off the network.

Top 3 Use Cases of LoRaWAN

  1. Cold Chain Monitoring: LoRaWAN can be used to monitor temperature in cold storage facilities and refrigerators, sending real-time data that can penetrate through walls to ensure perishable goods are kept within the required temperature range.

  2. Asset Tracking: LoRaWAN can track the location of vehicles and shipping containers, making it useful in logistics and supply chain management.

  3. Smart Metering: LoRaWAN can be used to monitor energy usage through smart meters. Energy companies can collect data in real-time, allowing for efficient management of energy distribution.

Increasingly, LoRaWAN has become the primary technology for IoT applications and has quickly overcome competing wireless technologies in terms of capabilities, cost, and scalability. 


Data transferred by LoRaWAN technology have industry standard AES-128 standard end-to-end encryption. Software and firmware updates can be installed remotely, allowing devices to stay up to date on security updates without needing human intervention or manual maintenance. 

Ensuring peace of mind with the reliability of LoRaWAN

At Therma°, we leverage LoRaWAN to ensure temperature and humidity data are reliably relayed to users, allowing for better peace of mind as well as accurate automated logging that increases the productivity of thousands of business and organization leaders across North America.

When too many people use too much electricity at the same time and demand for electricity exceeds what base load power plants can handle, financially and environmentally expensive peaker plants are turned on to help supply the additional electricity (which you pay for both from your wallet and through the quality of the air you breathe).

By shifting your cooling systems' energy usage away from these high demand periods, Therma helps reduce the need for peaker plant sourced electricity.
For a typical organization, each business location would have one hub and each cooler unit would have one sensor

Hubs and sensors can stay connected over a distance of up to around 1200 feet . Organizations that will have sensors spread out over more than 1200 feet will need additional hubs.
