Abstract
There is a major expansion in the market of wireless communications services in urban areas. New regulatory environments as well as rivalry in the communications industry necessitate that these systems be arranged quickly and at low cost. Computer-based radio propagation prediction tools are strong candidates for this goal. This paper provides an extension of pathloss analysis in urban environments in Oman. The paper addresses the applicability of Okumura-Hata model in an area in Oman in GSM frequency band. Trigonometric Regression Model is used for data prediction at unknown nodes. These can be used to make desired forecasts. The results are acceptable, can be used primarily for OMAN, and can be extended for other regions.

Summary
Mobile communications is currently at its fastest growth-period in history; due to enabling technologies, which permit wider deployment. Propagation models are useful for predicting signal attenuation or path loss which may be used as a controlling factor for system performance or coverage so as to achieve perfect reception [1]. It has been found that the mechanisms behind electromagnetic wave propagation are diverse and characterized by certain phenomena such as reflection, refraction and diffraction of waves. These phenomena induces signal scattering, fading and shadowing along the signal path and their effects can best be described (in a large scale) by the path loss exponent which defines the rate of change of attenuation that the signals suffers as it propagates from the transmitter to the receiver. The key idea of modern cellular systems is that it is possible to serve the unlimited number of subscribers, distributed over an unlimited area, using only a limited number of channels, by efficient channel reuse
