  1. Here the estimates for VR target the highest user experience with 24K resolution and a frame rate of 120 (ref. 4). Note that different VR devices and user experience standards are estimated to coexist in future deployment. Thus, the user transceivers must be flexible to support different data rates and formats. The estimates for the connected car fleet is obtained by considering ‘AI drivers’ user cases, where the car fleets exchange information including raw sensor data, vehicles’ intention and coordination, enabling cooperative perception for AI drivers10. In contrast to conventional applications that predominantly require high bit rate for data transmission (for example, video streaming), the above time-critical applications require bounded low latency in conjunction with the ability to scale across a large number of consumer devices.
