Performance comparison of exploiting different millimetre-wave bands in 5G cellular networks

Millimetre-wave (mm-wave) bands are considered an interesting candidate in the fifth generation (5G) mobile networks due to the high available bandwidth at these bands. Understanding the propagation performance of different mm-wave frequencies is an important issue to enhance the futuristic cellular networks. This paper investigates and compares the propagation performance of different mm-wave bands with the ultra-high frequency (UHF) by evaluating coverage and rate trends. The proposed scenario applied a map-based model for the base stations (BSs) deployment in university campus with a random distribution of users. The path loss models are determined by specifying the actual buildings' locations within the real campus map. Simulation results showed that the dense deployment of BSs will enhance the coverage of all mm-wave frequency bands and will offer limited noise networks. Comparison results showed that although the 73 GHz bands could provide good coverage with the lowest interference effects, it is still limited to small cell size. Also the 73 GHz bands results showed the higher rate achieved due to the large available bandwidth in this band.
