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. The path loss values, PL(.) are expressed

Where, fc is carrier frequency (in MHz) hb is based station antenna height (in meters) hm is mobile antenna height (in meters) d is base station to mobile distance (in Km) a(hm) is correction factor (formula varies for urban and dense urban ) Line of Sight (LOS) model The LOS model is a simpler model well suited to super high frequency microwave links where LOS is key. It factors in terrain data and antenna heights to provide a clear yes/no result. It starts where the ITM model finishes at 20GHz and extends the maximum range up to 100GHz. for log-normal shadowing path loss model with generic values. given in [65] is included .

The propagation path loss model is an empirical math-ematical formulation to characterize behaviour of the radio Waves as a function of the radio waves as a function of fre-quency, surrounding environment and distance[9]. 2.

Different operating frequencies and antenna polarizations are considered to verify the observations. the path loss exponent is expected.

Many translated example sentences containing "model assumptions" return to an increasing path from 2011 onwards, driven by a fairly optimistic demand assumptions used in the rating model deviate from the actual default and loss rates.

In addition, a large amount of signals in a UDN are transmitted from the near-ﬁeld of a receiver, and these signals experience less attenuation owing to sparse shadowing, i.e.
