MWC19 will be all about 5G: mobile service providers will officially announce commercial deployments; handset manufacturers will showcase 5G smartphones and the rest of the supply chain industry will announce new products and services to support these first network deployments. There will be many concepts and technologies developing in parallel to 5G at MWC19, including AR/VR, rich media, robotics, drones, and several other use cases across many end markets. Most of these will likely be proof of concepts or ideas rather than actual live implementations. The majority of 5G developments focus on mobile broadband now, and the US has a significant lead. Several mobile service providers, including AT&T have discussed that AI will be a critical technology to accelerate 5G deployments.
