Abstract
With the widespread deployment of 5G gaining pace, there is increasing interest in deploying this technology beyond traditional Mobile Network Operators (MNO) into private and community scenarios. These deployments leverage the flexibility of 5G itself to support private networks that sit alongside or even on top of existing public 5G. By utilizing a range of virtualisation and slicing techniques in the 5G Core (5GC) and heterogeneous Radio Access Networks (RAN) at the edge, a wide variety of use cases can be supported by 5G. However, these non-typical deployments may experience different performance characteristics as they adapt to their specific scenario. In this paper we present the results of our work to model and predict the performance of millimeter wave (mmWave) backhaul links that were deployed as part of the Liverpool 5G network. Based on the properties of the 802.11ad protocol and the physical characteristics of the environment, we simulate how each link will perform with different signal-to-noise ratio (SNR) and Packet Error Rate (PER) values and verify them against real-world deployed links. Our results show good convergence between simulated and real results and provide a solid foundation for further network planning and optimization.
Highlights
The ongoing deployment of 5G networks marks the start of evolution wireless networking as technologies converge and use cases extend beyond traditional home/business use
The vast range of technologies and techniques that represent 5G, both in the core and at the edge, make it very complicated to define exactly what 5G ‘looks like’ and how it performs in every situation
In Liverpool, a 5G network has been deployed by a consortium including the local council and healthcare providers, technology firms and academic institutions to support healthcare and community care services
Summary
The ongoing deployment of 5G networks marks the start of evolution wireless networking as technologies converge and use cases extend beyond traditional home/business use. This has implications for a range of environments, from dense urban deployments right through to sparse rural usage. 5G deployments are being considered by providers beyond traditional Mobile Network Operators (MNOs) to provide connectivity and services for a wide range of uses These include private 5G for use in Industrial Internet of Things (IIoT) and Industry 4.0 use cases, and community-based efforts such as those delivered by Liverpool 5G. Millimetre wave (mmWave) techniques ranging from 30 to 300 GHz have become a feasible alternative, with larger bandwidth and unprecedented peak data
