llite networks (number of broadband subscriptions per 100 inhabitants). Regarding the practical implementations, SSC services are all based on the ICT dimension, including fixed and mobile/wireless access networks as well as deployed SSC services. Considering the focus of 5G mobile network to network slicing, one may expect wider deployment of SSC services with the 5G deployments in the 2020s and beyond. How- ever, different SSC services may use different network slices which are dependent upon their QoS requirements as well as end-points (e.g. human users or machines/devices) [15]. eMBB is convenient for using tourist guide SSC service based on video services with different video resolutions (e.g. HD, Full HD, 4K) and augmented or virtual reality. Similarly, V2I (vehicle to infrastructure) infotainment services based on video stream- ing to passengers or vice versa (by using cameras on vehicles) may utilize eMBB in 5G (or mobile broadband in 4G or 3G). V2I assisted driving has strict QoS requirements such as guaranteed bitrate, very low delay, and very high reliability. This service belongs to critical IoS services, for which are the most convenient URLLC network slices in 5G. However, as one may assume, most of the SSC services will be based on non-real-time machine type communications, which will include many devices per square kilometer (massive deployments) connected via the mobile network such as 5G (Table 7.7). The mMTC services require minimum connectivity bitrates, have higher tolerance to delays (e.g. delays can be in range of seconds), and are served in best-effort manner through the mMTC network slices. Overall, the SSC services can be provided by using different standardized fixed and mobile access technologies. Having in mind that SSC will typically use mMTC commu- nication (for most of SSC services) the mobile networks are primarily in the focus for such use. However, WiFi access networks (best-effort or IEEE 802.1 for QoS support) are also convenient for mMTC services or generally for best-effort
