IoT use cases and requirements on technology

New use cases with varying requirements for connectivity are emerging as the IoT matures. Today there are two evident classes of use case: Massive IoT is all about high numbers of connected devices, whereas Critical IoT focus on high reliability and ultra-low latency.

The Low Power Wide Area (LPWA) applications for Massive IoT, such as building automation, city parking, smart agriculture, smart grid, logistics, tracking and fleet management demand connectivity that is reliable and easy to scale. The connectivity shall be able to provide extended coverage for low cost devices in remote locations and support long battery life time.

The Critical IoT applications are based on real-time communication and require connectivity that is highly reliable and available with ultra-low latency.  Safety and security are high – where trust in the system, including data, is essential and, in cases such as remote surgery and emergency rescue, potentially lifesaving.

Use cases and requirements

For business efficiency, flexibility and adaptability are required to be able to introduce new services fast to market, and connect and manage the growing numbers of diverse IoT devices in a resource efficient way. For customer satisfaction, the performance of IoT services need to be optimized for different business segments, and resources adapted dynamically to new traffic patterns, while for instance the amount of data shared may largely vary in time from different IoT device types.

There is also the need to mitigate the risk of malfunctioning devices generating signaling storms and affecting network services. Trusted security solutions are needed to ensure proper authentication and authorization of IoT devices in the network.
