LTE-M and NB-IoT meet the 5G performance requirements

Connectivity is a foundation for the Internet of Things. As a result, the type of access required will depend on the nature of the application. The access technology characteristics span from Critical IoT, with high demands for reliability, availability and low latency, to Massive IoT for low-cost devices with low energy consumption and wide area coverage.
Cellular technologies can serve both.

In this blog post, we will explain how the radio access technologies standardized by 3GPP, with focus on Release 15, address the 5G massive IoT requirements.

LTE Positioning and RTK: Precision down to the centimeter

Precise positioning based on global navigation satellite systems (GNSS) has become increasingly relevant for commercial use cases across different areas. Why? GNSS receivers are now more affordable and available than ever – existing most commonly within mobile handsets. GNSS positioning is based on information about signals and positions of multiple satellites, and is often assisted by information from mobile devices, provided by cellular network operators. Real Time Kinematic (RTK) is a technology that greatly improves precision of GNSS positioning, narrowing it from a few meters to mere centimeters. However, the challenge of RTK is in supporting all different devices that will be used in mass-market use cases, for example autonomous vehicles. LTE networks can now meet this challenge and provide users with precise positioning support.

Next stop: Zero-touch automation standardization

Future telecommunication networks and services will need to take human intervention out of the loop. Zero-touch automation will be imperative to manage increasingly complex networks and short service life-cycles.

In this post we discuss zero-touch network and services automation prospects and introduce the main aspects of the recently started ETSI ZSM standardization group: the organization, status, and the challenges that the ICT industry will face in the pursuit of a truly zero-touch automation of network and services.

New tech in wireless communication & the growth of ubiquitous radio

Availability of a ubiquitous high capacity radio that can provide sharing of data anywhere and anytime for anyone and anything is one of five key technology trends for the future listed by Ericsson’s CTO Erik Ekudden. In other words, wireless access is no longer just for people. In fact, wireless access will provide connectivity for any kind of device that may benefit from being connected. It should also be available anywhere, in the office, at home, on the street, in the forest…the list is almost endless.

Untangling Industrial IoT networking

Industrial IoT (IIoT) systems are rapidly growing larger, more distributed and gaining new capabilities. Similarly, the diversity of IoT applications will result in diversity in networking needs. Our Mobility Report forecasts 20 billion connected IoT devices by 2023, which will bring scale to the equation too. IIoT system designers and network engineers need to consider many different aspects when designing industrial networking systems. This includes the choice of networking technologies, that will lead to a successful network deployment.

Trust technologies for security assurance

The potential of the network platform where humans, machines, basic and AI-driven services will complement each other is so immense that it’s hard to grasp in all its aspects. Nevertheless, because our society will depend so heavily on this network platform to function properly, we are faced with a quite simple and highly relevant question: “is it secure?”

The emergence of the Internet of Skills

A next step in the connected world is to enable any human being to teach, be taught and execute actions remotely. In this way, human skills can be delivered or acquired without any physical boundaries, spreading knowledge globally at a faster and more efficient way. This is commonly referred to as the Internet of Skills and is expected to be a key component of the future digitalized world.
