Whether you're building applications for industrial, medical, agriculture, transportation, utilities or another industry, you're likely to spend lots of time integrating cellular modems and RF modules into OEM IoT devices. Regardless of location and the application, you want easy connectivity. That's where the Digi XBee® Cellular LTE modem product line can help.
In this article, we'll introduce the Digi XBee ecosystem and show how easily you can get started with our robust offerings designed for the toughest conditions. Digi XBee Cellular is part of this extensive ecosystem of supporting tools, code libraries, pre-certified modules, development kits, design and build services, and many more resources - all supporting rapid prototyping and development, quick time-to-market and complete product lifecycle management for a reliable and secure product.
Learn about the capabilities and use cases of Digi XBee Cellular Cat 4
XBee® is a registered trademark of Digi International. The Digi XBee family of modules supports a range of popular wireless RF communication protocols, from mesh networking to 802.15.4 and LoRaWAN, as well as a range of cellular bands and technologies. Our growing Digi XBee Cellular LTE modem line supports cellular LTE Cat 1, LTE Cat 4, LTE-M and NB-IoT today. Millions of Digi XBee modules are deployed in a vast range of use cases across the globe, from agriculture applications to solar fields to a wide range of industrial use cases - and a growing number of those are cellular due to the ubiquitous nature and availability of cellular networks.
Both XBee RF and cellular modules are excellent choices, depending on the parameters of your application. The pros and cons are fairly straightforward:
An additional consideration is physical distance between nodes in your network. When you have a series of assets to connect within relatively close proximity to each other, perhaps within a thousand meters, you can use RF modules on a local network. When you have a few individual assets to connect, though, it is much simpler to use cellular.
So, let's say you've decided to go with an embedded cellular modem or module, vs. an RF module. How do you select the right one for your application? Let's discuss.
Generally, the right cellular technology is the one that's available at your deployment location. According to Counterpoint Research, in 2022, 4G LTE and NB-IoT accounted for almost 90 percent of cellular IoT connections.
In China, NB-IoT has gained popularity while Japan, Australia and North America gravitated to LTE-M technology for lower-speed IoT installations. However, Europe embraced both NB-IoT and LTE-M. So, whatever country you're deploying to, find out if LTE-M or NB-IoT networks have been deployed by the carrier in that region.
LTE-M and NB-IoT are an excellent choice when you need to know the location of your assets and how long they've been there, but don't necessarily need continuous updates. This passive asset tracking uses very little data.
In many cases, you will find higher-speed LTE networks such as LTE Cat 1 and LTE Cat 4 deployed globally. In fact, you may select the LTE Cat 1 and the LTE Cat 4 for their large global footprint, and not their speed, to ensure the best reliability when connecting to a network. LTE-M and NB-IoT have good network coverage. However, because these technologies require support from towers, only towers with updated software can host these networks. The U.S. probably leads most other countries in the world with tower software updates.
When looking at the suite of Digi XBee Cellular LTE modems, each of these options has some excellent features and capabilities for different applications.
All Digi XBee 3 Cellular LTE modems come pre-certified for global cellular deployments. This means they help accelerate development times and remove the cost burden associated with carrier certification.
Cellular is essentially ubiquitous across the planet. And that's one of the reasons we Digi makes modules with fallback to the 2G and the 3G networks; they're more likely available in marginal coverage zones. With Digi XBee Cellular solutions, deploying cellular-connected assets is easy. And global. And flexible. And stable.
Cellular allows OEMs to remotely access equipment to improve insights and automation, and better service customers. In fact, customer service is a big selling point for IoT. Let's look at some interesting applications for XBee Cellular modems.
Some of the key applications we see for cellular come from that vast agriculture industry.
Electric vehicle charging is one of the fastest growing industries, with the rapid growth of the EV market. Cellular in these applications supports data collection, financial transactions, user interface and video management and automation.
In the service station scenario, one Digi customer used cellular communications to notify service personnel when coin-operated air pumps were full. Instead of sending a driver out to collect the coins from machines that might be mostly empty, IoT sensors and cellular applications detected the need for servicing and sent notifications. The system was so successful that the business was able to get a return on their investment within 9 months of deployment.
In addition to creating a more efficient collection system, the stations learned how the sites operated the machines and how customers used it even the locations with the most and least usage. As a result, they made changes to their offerings based on this new information - largely enabled by cellular communications.
Today's smart cities are looking for ways to reduce emissions and energy usage, lower their carbon footprint. Every city service that can be monitored remotely is a potential candidate for cellular modems - from smart street lighting to water and wastewater management services to trash compaction and sanitation systems.
Finally, some companies use cellular communications to optimize their operations in ways that benefit the planet. For example, remote sensing enables companies to send fewer trucks, optimizing routes and sending trucks only when needed. By reducing truck rolls, intelligent IoT systems play an important role in reducing greenhouse gas emissions across all sorts of industries.
There are industrial sensors and vast amounts of industrial equipment everywhere, but most of it is not connected today. What a tremendous opportunity for OEMs to build in IoT connectivity so their customers can start gaining new insights from operational data that can improve their business models or even inform new ones. That's a big return on investment. It's a digital transformation that elevates your organization above your competition. Ready to take the next step?
Digi International, a leading provider of Internet of Things (IoT) connectivity solutions, has created the XBee Global Cellular family specifically as dependable, compact solutions with Bluetooth Low Energy and end-device carrier certifications. The modules were purpose-built to be used worldwide and are equipped with Global Navigation Satellite System (GNSS) positioning. Developers and original equipment manufacturers (OEMs) looking to add reliable cellular IoT connectivity to their devices or IoT gateways will find these solutions simple to implement and update.
To round out the ecosystem, Digi XBee Studio enables developers to design, build and test Digi XBee Global Cellular networks, and Digi Remote Manager® connects seamlessly to XBee Cellular LTE modems for remote monitoring, management and mass firmware updates. Finally, all Digi Cellular modems support MicroPython programming, Bluetooth, GNSS positioning for geolocation and Digi TrustFence® security.
