The next industrial revolution, sometimes referred to as Industry 4.0, is already ongoing, fueled by technology advancements in big data, automation and cyber physical systems. To achieve their full potential, these new processes and operating models require high-performance connectivity. Ultra-reliable low latency communication (URLLC) is a new set of 5G NR capabilities, expected for 3GPP Release 16, that can enable operators and enterprises to address a diverse range of high-performance industrial use-cases. This webinar will investigate 5G NR, including the support for private industrial networks and URLLC capabilities. Using the "factory of the future" concept as an example, it will show how 5G NR can help to transform industrial IoT by making it more dynamic, flexible and adaptable to market demand.

5G expansion into new use cases & verticals
Reliability from spatial diversity
Spatial diversity can overcome radio shadowing
in challenging radio environments
Key technology to provide ultra reliability for
challenging industrial IoT applications
Capacity from spatial multiplexing
Allows multiple transmissions at the same time to
multiple location without interfering
Can also be used to by multiple operators to share
spectrum more efficiently

Theoretical tradeoff between multiplexing and diversity
Multiple transmit and receive antennas with uncorrelated signal paths create spatial dimensions

multiple spatial dimension from multi-path propagation
to increase capacity and coverage and cell edge.

capacity and/or spatial diversity for reliability
