Wireless links are characterized by fluctuating quality leading to variable\npacket error rates which are orders of magnitude higher than the ones of wired\nlinks. Therefore, it is of paramount importance to investigate the limitations\nof using 5G wireless links for internet of things (IoT) applications. 5G\nwireless links in IoT need to assure determinism of process flows via realtime\ncommunication anytime and anywhere, which is an utmost requirement for multiple\nverticals like automotive, industrial automation and aerospace. Based on a\nspace-time approach, in this work, we provide novel definitions of wireless\nlink availability and reliability, assuming a number of access points (APs) and\nend points (EPs) deployed over a fixed area. Our objective is to analyze the\navailability of a service in both domains. In the space domain, we characterize\nspatially available areas consisting of all locations that meet a performance\nrequirement with confidence. In the time domain, we propose a channel\nallocation scheme accounting for the spatial availability of a cell. To\nemphasize the incurred space-time performance trade-offs, numerical results are\npresented, also highlighting the effect of different system parameters on the\nachievable link availability and reliability.\n
