Cellular Router or Modem: A Basic Guide to IoT Hardware

What is a cellular IoT modem?

IoT Modems are the chipsets or components integrated into Internet of Things (IoT) gateways and routers for connecting to a variety of wide area, or WAN, networks.

Unlike a traditional modem, an IoT modem is specifically designed to provide reliable connectivity for IoT and machine-to-machine (M2M) applications.

Let’s say an IoT engineer wants to develop cellular connectivity as part of her IoT solution. An embeddable IoT module/modem is the starting point for that solution.

But the design and development process can be challenging. An embedded integration generally requires a minimum of 4 to 6 months to accomplish — with radio-frequency (RF) expertise, dedicated hardware and software resources (along with reliable vendor documentation) — plus high-level support during the compliance and carrier-certification phase. Because this endeavor can be so complex, costly, and time consuming, most cellular IoT experts recommend embedding a pre-approved module like the OptConnect ema™ to drastically reduce their cellular product’s time to market.

Additionally, our OptConnect engineers have taken embedded cellular modules to the next level by creating a plug-and-play IoT modem called the ema:USB. This smart modem is the first of its kind, and doesn’t require many thousands of dollars and extra time to develop, which makes life even easier for IoT developers and operators.

What is a cellular IoT router?

A cellular IoT router is both a LAN device (managing local connections between IoT devices) and a wide-area WAN device (providing internet connectivity through a cellular network). An IoT router is designed to be reliable and secure, making it ideal for industrial, agricultural, and other IoT applications.

As mentioned earlier, most IoT routers contain an embedded modem to help ensure connectivity in remote areas where wired internet or Wi-Fi is unavailable.

Unlike most traditional routers, IoT routers:

Are designed for diverse IoT environments, including outdoor installations, remote areas, and tight-fitting spaces
Support a wide range of communication protocols, including Wi-Fi, Bluetooth, LoRa, and cellular (LTE, 5G, NB-IoT) for ultimate flexibility
Include more advanced security features like multi-tunnel VPN support, firewall protections, and intrusion detection sensors or systems
Feature remote management and monitoring capabilities that help administrators oversee large IoT portfolios, automatically update firmware, and troubleshoot their devices from a central location
Handle large numbers of connected devices and ensure reliable operation in mission-critical applications.
Operate well in a variety of environments where temperature extremes, dust, and moisture and other conditions may be present.

While an owner of a smart home doesn’t need an IoT router, it’s essential for businesses that work in IoT — especially for manufacturers, the energy sector, healthcare, retail, robotics, transportation, and other high-tech industries looking for machine-to-machine connectivity.

Choosing the right IoT router

Any enterprise trying to plan for an IoT deployment needs the right router before anything can move forward. For value-added resellers (VARS) that need a scalable cellular solution for their chosen IoT application — whether that’s a fleet of EV chargers or a portfolio of smart vending machines — procuring the right IoT router is likewise critical.

For example, someone designing a project that will bring Wi-Fi to high-speed trains will definitely need a strong mobile connectivity solution. An RV manufacturer installing a cellular solution needs an ultra-reliable 5G solution — probably with 4G failback capability for areas where 5G is unavailable. A retail outlet may be fine with fixed connectivity, but a pop-up retail kiosk may not be.

Clearly, choosing the right cellular router demands special care and consideration for IoT applications. With that in mind, here are a few questions you should ask your preferred cellular connectivity vendor:

Is fixed wireless or mobile wireless best for my IoT application?
How many devices/machines can I connect to one IoT router?
What type of antenna goes with my preferred router?
Can you tell me more about your dual-SIM routers?
Do you provide an eSIM solution?
Do you provide carrier connectivity for the routers you sell, or do I have to set up a data plan myself?
What accessories are included with the router?
Do I need to manage the IoT routers myself, or does someone else do that?
Does the router come with a software platform for remote monitoring and management?
What kind of support is included in the event of problems with the router?

These are just a few examples of questions you should ask a managed wireless services expert. With detailed answers, you will have a better idea of the router (and data plan, and managed services) you may need for your IoT project.

Purchasing IoT Hardware from a Top-tier Distributor

While we’re on the subject of IoT vendors, consider this.

When investing in IoT hardware, it’s crucial to buy from a reputable distributor that offers a wide range of major brands. A top-tier distributor will have dozens of IoT devices in stock, data plans and SIM cards, comprehensive support, and robust warranty options. They can help tailor a solution to your requirements, whether you need a cellular router, modem, or another IoT device.
