Mobile operators are deploying millimetre wave (mmWave) 5G networks in crowded urban areas, such as sports arenas, stadiums, airports, concerts and other large venues. Operating at frequencies of 24 GHz and higher, these 5G Frequency Range 2 (FR2) networks are able to deliver multi-gigabit data rates and very low latency . The mmWave bands offer a 10-fold increase in available contiguous bandwidth compared to sub-6 GHz 5G Frequency Range 1 (FR1) bands. As a result, mmWave networks can handle a greater number of connections with greater peak individual data rates. This document looks at the technical mitigation strategies to improve the performance of 5G mmWave networks in both indoor or outdoor scenarios.
