On the Capacity of a 5G Network for URLLC

—The ability to support ultra-reliable low-latency communications (URLLC) is one of the main features of fifth-generation (5G) networks. Strict requirements to the quality of service (QoS), which are typical for URLLC traffic, significantly reduce the wireless network capacity compared to the capacity for mobile broadband traffic. Using simulations, we study the dependence of the URLLC traffic network capacity on the main network parameters such as the used channel bandwidth, cell radius, and the packet delivery time as well as the packet loss ratio that are admissible for URLLC traffic.
