Chapter 1 Introduction
1.1 Background
The signal strength received on the MS (Mobile Station) from the BS (Base Station) is generally affected at 3 stages. The first stage is signal generation at the BS (Base Station), the second stage is propagation, and the third stage is the MS (Mobile Station). Until now, there has not been an empirical calculation of signal propagation, which is currently used is prediction based on experiment and research (no theory). One of them is Okumura-Hata where researchers from Japan surround urban, suburban, and rural areas, trying certain distances and measuring the signal obtained by MS (Mobile Station) from BS (Base Station). To measure signal strength using Okumura must provide many tables based on the situation of the area. Even though using Okumura is accurate, it wastes time because we have to check the tables. Hata derived the calculation formula from Okumura but it also took a long time to compute manually. In this paper, calculations will be made from BS (Base Station) to MS (Mobile Station) based on the Hata formula in MATLAB software based on some data. What is calculated is the RX (Received) Power at MS (Mobile Station) in Urban, Suburban, and Rural areas from a distance of 1 km to 20 km.
1.2 Problem
What are the results of the calculation of receiver power in MS (Mobile Station) from transmitter BS (Base Station) in urban, suburban, and rural areas based on the Hata formula using MATLAB software?
1.3 Objective
To make signal propagation calculations from BS (Base Station) to MS (Mobile Station) based on Okumura-Hata in MATLAB.
1.4 Benefit
It is more energy and time efficient to find signal propagation calculations.
