Abstract

Abstract Summary

Overview

Fixed wireless access (FWA) is presented as a competitive alternative to fiber deployments, offering cost savings and utilizing the mmWave bands, specifically the unlicensed 60 GHz frequency. This study conducts a thorough evaluation of FWA network deployments in both urban and rural settings within Belgium.

Methodology

The research involved the development of a sophisticated network planning tool that leverages the IEEE 802.11ay standard. This tool is designed with multi-objective capabilities that aim to maximize user coverage and achieve a minimum bit rate of 1 Gbps, while also minimizing the necessary network infrastructure.

Findings

The selection of optimal locations for edge nodes (EN) is crucial for attaining more than 95% user coverage, particularly in urban areas affected by street canyons.
In rural areas, approximately 75 ENs per km2 are necessary, while urban environments may require up to 300 ENs per km2.
Environmental elements such as vegetation and rain have significant effects on network performance, with potential coverage reductions up to 5% due to heavy rain and infrastructure increases by up to 15% depending on deployment strategies.

Conclusion

The study highlights the importance of strategic EN placement and addresses the impact of environmental conditions on network efficacy. Through extensive simulations, it provides vital insights for optimizing FWA deployments in differing geographic and climatic conditions.
