The study will involve two Path Loss Path loss models describe the signal attenuation between a transmit and a receive antenna as a function of the propagation distance and other parameters. Some models include many details of the terrain profile to estimate the signal attenuation, whereas others just consider carrier frequency and distance. Path loss is sometimes categorized as a large scale effect (in contrast to fading which is a small scale effect). According to the WINNER-II model the path loss can be calculated as: WINNER-II Path Loss Equation. Here d is the separation between the transmitter and receiver in meters, f c is the frequency in GHz, A is the path loss exponent, B The power law model is a commonly used empirical path loss model in indoor environment.

Consequently, a model is preferable that accurately captures the signal attenuation, allowing to estimate the impact of radio range and contact duration. A new path loss model is proposed for the 28 GHz and 38 GHz frequency bands.

This model was derived from real-world data on UHF and VHF television transmissions in several large cities. This calculator is used to calculate Land Mobile Path Loss.

loss corresponding to each measurement. Path loss can be defined as the ratio of the transmitted to received power, usually expressed in decibels. The equation for the Least Square (LS) regression analysis shows the path loss at distance d in the form PL(d)=PL(d0)+10nlog10 d d0 (1) where, d0 is the reference point at 1 km and n is known as the path loss exponent.
