The test will verify data transmission and operational performance required to remotely control the cart from a long distance via the extra-high speed, large capacity, low latency and massive-device connectivity. This will be the firms' second joint trial of 5G technologies, following a trial conducted in Japan in 2017 to test the real-time transmission of high-definition video via a 5G system to a 4K digital-signage system fitted to the outside of the cart.

The New Concept Cart SC-1 is a highly conceptual vehicle that incorporates artificial-intelligence (AI) and robotics technologies developed by Sony. Image sensors that exceed human vision are mounted on the vehicle's front, rear and both sides to provide the remote driver with high-quality video of the surrounding area, and also to on-board passengers, for example, to show them entertaining augmented-realty scenes of the surrounding area.

The 4K digital-signage system can be used for displaying advertisements and other content in high-quality resolution to passersby.
