“…Several formulations have been proposed to scale long-term attenuation statistics, each with applications and limitations [12,27]. Most of these relations are intended for scaling attenuation statistics (that is, for calculating SAR), not for instantaneous (real-time) scaling of attenuation: I. SAR-based method: Instead, in real-time applications, the frequency scaling principle has been proposed to provide static scaling attenuation.…”

“…The drawback of this technique is that it needs the coefficients k and α derived through the frequency and the DSD. This procedure was simplified in [27], and through the empirical formula, ITU-R ( 25) can be adopted. The polynomial-based frequency scaling technique was proposed in [43,44]; i. ITU-R model: ITU-R has adopted a model to predict frequency scaling as [45]:…”

“…H(Φ 1 , Φ 2 , A 1 ) = 1.12(Φ 2 /Φ 1 ) 0.5 (Φ 1 A 1 ) 0.55 (27) The applicable frequency of this model [45] is limited to 7-55 GHz; ii. Use of the specific attenuation relation: Using the power-law-based specific attenuation relationship, we can write:…”

The scaling of rain attenuation methods is promising to quickly estimate power degradation in radio links due to rain with known findings from previous measurements. Although the frequency scaling of rain attenuation technique was introduced ages ago, it has not been addressed adequately. Furthermore, some emerging scaling techniques have recently been proposed in the literature through polarization, elevation angle, and pathlength parameters. A survey paper might play a vital role in order to comprehend all these study areas systematically. However, a survey paper on this research field is currently unavailable in the literature. This review categorizes all the research works using the inherent properties of scaling techniques. Furthermore, this study presents a comparative investigation of parameter-based scaling techniques by considering their working procedure, applicable frequency ranges, and innovative ideas incorporated with all of these models.
