What is IoT Connectivity?

Quick summary of IoT connectivity

IoT connectivity refers to the technology that enables devices to communicate with applications, servers, and users over the internet. It's the backbone that powers the Internet of Things (IoT), allowing data, commands, and insights to flow seamlessly between connected devices, from simple sensors to advanced machinery.

How IoT connectivity works

IoT connectivity enables devices equipped with sensors and embedded systems to communicate with application servers via various network technologies (e.g., cellular, WiFi, LPWAN, Bluetooth). Data collected by the device is transmitted over the network using protocols such as MQTT, CoAP, or HTTP to cloud platforms or edge gateways. There, the data is processed, analyzed, and used to trigger actions, send alerts, or enable remote control. The IoT connectivity layer ensures secure, reliable, and often bi-directional communication between the device and the application ecosystem.

Key Features of IoT Connectivity:

·       Enables device-to-cloud communication using networks like cellular, WiFi, LPWAN, and Bluetooth.

·       Supports real-time data transfer and remote control via protocols like MQTT, CoAP, and HTTP.

·       Secure and bi-directional communication for reliable IoT operation.

·       Flexible connectivity options tailored to range, power, and data needs.

What types of connectivity can be used for IoT?

Multiple technologies can provide IoT connectivity. The right one depends on the application, location, data needs, and budget:

Cellular networks

• Ideal for wide-area, mobile, or large-scale deployments.

• Supports 2G/3G/4G/5G and low-power variants like NB-IoT and LTE-M.

• Offers standardized coverage and high IoT security solutions.

WiFi

• Suitable for fixed, local environments (e.g., homes, offices).

• Common in consumer IoT like thermostats or cameras.

Bluetooth & BLE

• Great for short-range communication, like wearables or accessories.

• BLE offers extended range and lower power for confined environments.

Low Power Wide Area Networks (LPWAN)

• Useful for low-data, long-range applications like environmental sensors.

• Considerations include network availability and whether you need private or shared infrastructure.

Other legacy technologies (Zigbee, proprietary mesh)

• Still used in niche or legacy deployments but declining in popularity.

Choosing the right connectivity for IoT

Selecting the ideal IoT connectivity solution depends on your specific use case and environment. To ensure your devices perform reliably and efficiently, consider these key factors:
• Data rate & volume
• Power usage
• Range & location of devices
• Geographic coverage
• Cost (upfront and operational)
• Ease of setup & management

The ultimate goal is simple: connect your devices reliably and cost-effectively so your application delivers value to your business and your customers.

How can IoT help your business?

Implementing IoT connectivity can transform business operations across many industries. With the right approach, IoT enables:

• Cost savings through automation, energy efficiency, and predictive maintenance.

• Improved productivity by streamlining operations using real-time data.

• Remote monitoring and control of assets, leading to faster response times.

• Enhanced customer experience through personalized and connected services.

• Supply chain optimization with accurate, real-time visibility.

• Predictive maintenance that reduces downtime and extends equipment lifespan.

• New revenue streams via data-driven services or usage-based models.

• Sustainability gains by minimizing waste and energy consumption.

Whether your goal is to reduce operational costs, grow revenue, or both, IoT connectivity lays the foundation.

Why choose cellular IoT connectivity?

While many technologies suit IoT, cellular connectivity stands out for its versatility and reliability in commercial and industrial applications. Here’s why:

• Global coverage – Operates anywhere with mobile networks, even across borders.

• Mobility – Devices stay connected in transit (ideal for logistics, tracking, etc.).

• Scalability – Handles large volumes of connected devices with ease.

• Security – Encrypted communication and robust SIM authentication.

• Low-power options – NB-IoT and LTE-M deliver battery life of 10+ years.

• Flexibility – Use eUICC/eSIM to switch networks without site visits.

• Managed service – Connectivity, SIMs, and networks handled by experts like Pelion.

• High-speed, low latency – Supports demanding use cases like CCTV and passenger WiFi.

The right connectivity technology depends on your goals and environment. Cellular IoT is a robust, scalable, and secure option for many use cases, especially when wide coverage, reliability, and low power usage are essential.
