Sixth generation (6G) radio access technology is expected to support extreme communications requirements in terms of throughput, latency and reliability, which can only be achieved by providing capillary wireless coverage. In this paper, we present our vision for short-range, low power 6G ‘in-X’ subnetworks, with the ‘X’ standing for the entity in which the cell is deployed, e.g., a production module, a robot, a vehicle, a house or even a human body.
