Key Technology Areas Driving 6G Requirements and KPIs

Technology Areas Impacting 6G Needs and KPIs

As the telecom sector moves past 5G, research and standardization groups are laying the groundwork for 6G networks, which should be here around 2030. Unlike 5G that was all about speed and capacity, 6G will focus on intelligence, sustainability, precision, and reliability.

The diagram provided shows how various 6G needs, tech enablers, and KPIs (Key Performance Indicators) are connected. By examining these links, we get a clear sense of how 6G will be crafted to support next-gen applications like holographic communications, autonomous mobility, industrial IoT, and the metaverse.

Core 6G Requirements

On the left side of the diagram, there are six main requirements that are key to 6G development:
