En Sensors (Basel) (Vol. 21, Número 19). https://doi.org/10.3390/s211966081424-8220http://repositoriobibliotecas.uv.cl/handle/uvscl/3023The 5G cellular network is no longer hype. Mobile network operators (MNO) around the world (e.g., Verizon and AT&T in the USA) started deploying 5G networks in mid-frequency bands (i.e., 3-6 GHz) with existing 4G cellular networks. The mid-frequency band can significantly boost the existing network performance additional spectrum (i.e., 50 MHz-100 MHz). However, the high-frequency bands (i.e., 24 GHz-100 GHz) can offer a wider spectrum (i.e., 400 800 MHz), which is needed to meet the ever-growing capacity demands, highest bitrates ( 20 Gb/s), and lowest latencies. As we move to the higher frequency bands, the free space propagation loss increases significantly, which will limit the individual cell site radius to 100 m for the high-frequency band compared to several kilometers in 4G. Therefore, the MNOs will need to deploy hundreds of new small cells (e.g., 100 m cell radius) compared to one large cell site (e.g., Macrocell with several km in radius) to ensure 100% network coverage for the same area. It will be a big challenge for the MNOs to accurately plan and acquire these massive numbers of new cell site locations to provide uniform 5G coverage. This paper first describes the 5G coverage planning with a traditional three-sector cell. It then proposes an updated cell architecture with six sectors and an advanced antenna system that provides better 5G coverage. Finally, it describes the potential challenges of 5G network deployment with future research directions.en-US5G5G COVERAGEANTENNA ARRAY MASIVEMILLIMETER-WAVEMIMOSINRArticulo
