Millimeter Wave Channel in Urban Micro / Urban Macro Environments: Path Loss Model and its Effect on Channel Capacity

The wireless communication operating in sub 6GHz channel models is facing challenges like user demand and data traffic. So, the Millimeter wave (mmWave) frequencies are introduced in 5G communication, and it is operating in 6GHz to 100GHz band. The propagation nature of the mmWave channel models is more complicated and it is prone to path loss, shadowing effects, and other atmospheric conditions. So the channel modeling for indoor and outdoor communication is a more challenging one. Various channel models are proposed for 5G communication. This paper focuses on the 3GPP TR38.901 channel model in Urban Micro (UMi), Urban Macro (UMa) environments. The pathloss and channel capacity is analyzed up to 100GHz frequency, most preferably 28GHZ, 38GHz, 60GHz and 73GHz. Higher frequency provides high pathloss and less capacity, but it covers wide band of frequencies.
