Abstract

In this thesis, the performance analysis of millimeter wave MIMO systems 60 GHz V-band wireless local area network communications in LOS and NLOS evaluated. This work based on capacity evaluation; coverage area compression; enhancement of channel bandwidth by using channel bonding methods; compare the received signal strength and compare the path loss of wireless local area network communications for 2.4 GHz, 5 GHz and 60 GHz frequencies. The evaluation of capacity in SISO and MIMO different antenna systems in numbers also compared for those three frequencies. In addition, the coverage area comparison between above frequencies used LOS and NLOS WLAN. For comparisons, 2.4 GHz IEEE 802.11n, 5 GHz IEEE802.11ac, and 60 GHz IEEE802.11ay may be using in path loss model are preferred for their respective frequencies because the equations can be formulating by IEEE802.11 standards for wireless local area network LOS and NLOS environments on this thesis study. This performance of millimeter wave MIMO systems 60 GHz V-band wireless local area networks communications computed by MATLAB. The capacity of those three frequencies compared in this study, so the capacity of 60 GHz is very high as compared with 5 GHz and 2.4 GHz. The 60 GHz 16x16 MIMO systems 12.96 GHz bandwidth value obtained 699.54 Gbps for LOS and 654.95 Gbps for NLOS by utilizing channel bandwidth bonding methods. The received signal strength and path loss of 2.4 GHz IEEE802.11n, 5 GHz IEEE802.11ac and 60 GHz IEEE802.11ay wireless local area network based LOS and NLOS environment analyzed. From this study the coverage area of 60 GHz, 5 GHz, and 2.4 GHz NLOS are 4.8 m, 17.9 m, and 25.7 m and for LOS of those frequencies are 9.75 m, 27.4 m, and 39.7 m respectively. In this study, the received signal strength value achieved 60 GHz - 38.0048 dBm, 5 GHz -66.42 dBm and 2.4 GHz -70.04 dBm for LOS and 60 GHz -38.1015 dBm, 5 GHz -66.5176 dBm and 2.4 GHz -70.1427 dBm for NLOS. Finally, this thesis achieved the path loss 60 GHz for WLAN LOS 85.29 dB and NLOS 100 dB respectively. Generally, 60 GHz have higher capacity, high channel bandwidth, high-received signal strength and lower coverage area compared to the aforementioned techniques.
