IoT requires consistent connectivity to construct networks and share data. Cellular IoT is one connectivity option, which operates in the licensed spectrum. This means it can only be used when assigned exclusively to operators for independent usage, ensuring reliability through a relatively consistent infrastructure. Cellular connectivity solutions are generally provided by larger operators who have access to licensed spectrum, as this comes at a higher cost. However, the global cellular standards means that IoT hardware is more easily obtained, the devices operational lifetime is generally much longer, and it’s virtually guaranteed by the network operators to be more reliable than other connectivity options. So, what are the core advantages of cellular IoT connectivity?
Global Coverage
The most reliable and logical connection option is cellular connectivity, with cellular towers already in place across the world and network gateways supporting remote deployments, cellular IoT connectivity can provide nearly ubiquitous global coverage. The extensive coverage already in place allows the management of devices being deployed in different areas of the world, which is key for IoT projects where accessing the data is essential. In most cases, you’ll be able to deploy as many devices to wherever they are needed and start operating straight away. Cellular roaming poses another option if you’re moving between regions or providing a solution in an unknown area, your provider will be able to facilitate seamless connectivity through a multi-network SIM. As 5G becomes more accessible across the world, cellular becomes a great solution for larger scale IoT deployments and will improve the overall speed and responsiveness of cellular connectivity.
Usability
Cellular is a top favourite among IoT connectivity solutions down to the increasing demand for extensive network coverage areas and low power consuming devices. The simplicity of deployment is a core advantage of cellular connectivity, deploy your device, activate your SIM to connect to your chosen network and you are all set. This SIM based connectivity disregards the need to set up to time consuming and complicated hardwired networks. With multi IoT device support, you can support millions of IoT devices through one use case. Cellular IoT connections are made up of several subcategories, meaning you can select the one that matches your data transmission needs and avoid paying for the most expensive solution. If your device doesn’t require constant connectivity and immediate reaction time, then you can choose a more affordable and suitable option for you. Emerging low power networks will help deliver the connectivity for the proliferation of devices & sensors and other cellular technologies like eSIM are quickly gaining popularity in the market, providing a flexible way to remotely connect devices throughout their lifetime, cost effectively, without needing a physical SIM card.
Reliability
As cellular operates in the licensed spectrum, the performance and reliability of communication is guaranteed. Most IoT SIM cards provided for IoT devices can switch between network operators, unlike consumer SIMs, automatically connecting to the strongest signal available to ensure consistent connectivity and minimised downtime. Technicians can remotely track interlinked devices, they are able to connect, disconnect and troubleshoot wherever they may be located, rather than manually fixing the systems. This minimises operational inefficiencies and reduces field service costs significantly. Cellular IoT connectivity also has a much greater battery life, cellular sensors transmit great volumes of data on a global scale, without losing considerable battery power by switching off the receiving section of the cellular module for a fraction of a second. 5G IoT SIM cards even have the ability to remove fixed line through its QoS.
Security
Security is another great advantage cellular connectivity holds over other solutions. As cellular networks use SIM cards for authentication, it proves difficult to hoax the identify of a device. With every device being kept separate, the data being transmitted is protected, with private APNs controlling network access and secure VPNs in place, your IoT devices will be safe against unauthorised access. Combining this level of security with a properly managed connectivity service will give you visibility and control that other connectivity options cannot give.
