Using LoRa and Google Cloud for IIoT Applications

Pairing LoRa connectivity with the Google Cloud Platform (GCP) can serve a wide range of industrial IoT (IIoT) use cases. The longevity and resilience of LoRa paired with GCP's robust architecture and commitment to scalable innovation provides industrial operators with the tools they need to build the world of tomorrow.

Industrial Internet of Things (IIoT) applications differ greatly from other consumer and enterprise applications for many reasons. They are often constrained by factors, including limited access to power, network connectivity challenges, network security requirements and hazardous physical environments. IIoT solutions must be designed with the highest standards across the board, from durability to battery optimization.

The Benefits of LoRa for IIoT

LoRa (Long Range) refers to the physical layer of a low-power, wide-area networking technology (LPWAN) made by Semtech. It operates in unlicensed sub-gigahertz radio frequency bands. As the name indicates, LoRa functions over long range, with coverage that greatly exceeds WiFi, Bluetooth or Zigbee networks and is capable of extending for dozens of miles under ideal conditions.

Deployed LoRa sensors communicate data asynchronously over these radio frequency bands to the nearest gateway device in an unacknowledged “Pure ALOHA” scheme. The gateway then receives and backhauls those messages to the cloud using cellular, WiFi or ethernet. These gateways can support upwards of tens of thousands of sensors each.

In many IIoT scenarios, access to local networks (WiFi/ethernet) is limited or restricted. Most industrial environments deal with automated or labor-driven mechanical and chemical processes that don’t depend on the internet to function, or they may pre-date the internet entirely. Additionally, it can be difficult or even hazardous to constantly service devices, so it’s important for sensors to be both durable and low power.

Most LoRa devices are designed to these standards (IP67, multi-year battery life), meaning that they can be installed with several gateways to cover an entire factory floor for a long term deployment. Furthermore, device authentication at the gateway and AES128 encryption ensure that data is tamper-proof until it reaches the cloud.

Enterprise Cloud: Google Cloud Platform (GCP)

To manage large scale sensor deployments, there are many requirements for a cloud platform to maximize the value from IIoT applications. Google Cloud Platform is uniquely positioned against other enterprise cloud providers in this regard. They offer a wide array of tools designed specifically for handling big data, from serverless analytics services to the global network of data centers and proprietary fiber to accelerate the speed of migrations and deployments. From security to device management to batch and real-time data processing, machine learning and more, GCP meets the needs of a range of IIoT (and IoT) use cases.

There are many reasons why IIoT applications differ significantly from consumer and non-industrial enterprise IoT applications. They’re often constrained by factors such as limited access to power, network connectivity challenges, network security requirements and hazardous physical environments. Consequently, IIoT solutions must be designed with the highest standards across the board, from durability to battery life.

Free Webinar: Architecting an IoT Solution with Google Cloud & LoRa

Date/Time: Thursday, February 28th, 2019, at 2:00 p.m. EST

Are you building an IoT solution? With the vast number of connectivity and cloud platform options available, designing, building, and scaling an IoT project can be a daunting task. Our team has been using Google’s Cloud IoT Core as build large-scale IoT deployments while also collaborating with the Google team, giving us deep, under-the-hood knowledge.

In our free webinar, we’ll share what we’ve learned building and rapidly scaling enterprise IoT solutions within the Google IoT Core ecosystem.

Leverege's mission is to provide software solutions and share actionable knowledge that give every organization the power to achieve more with less. In everything that we do at Leverege, we believe in amplifying human potential. We are constantly asking: how can we help organizations achieve more with less effort and enable them to do what was previously unimaginable? We believe that one of the best answers to this question lies in the Internet of Things (IoT) technologies, with machines and computers doing what humans cannot so that people are freed to do what only they can. And so we believe that value is created by empowering people—not making them obsolete—through end-to-end IoT solutions.
