Abstract
In this research paper, a signal propagation for microcells, based on building heights and distance from base station, is examined. The tests were carried out in an urban area. There were measured the signals’ path losses from two mobile network base stations depending on buildings highs and distances to them. The “Anritsu Cell Master MT8212A” spectrum analyser was used for signal strength measurements. The results are compared with well-known models. Based on experiment results a new propagation model is proposed for the examined area. DOI: http://dx.doi.org/10.5755/j01.eee.21.4.12786

For the past decade the networks of telecommunications have been expanding at a tremendous speed so older cellular technologies are becoming obsolete and updated by newer ones, for example, the Advanced Long Term Evolution (LTE-A)

The aim of this paper is to propose an empirical signal propagation model for microcells at 900 MHz frequency range based on the distance between user equipment (UE) and base station (BS) and different building heights
Summary
For the past decade the networks of telecommunications have been expanding at a tremendous speed so older cellular technologies are becoming obsolete and updated by newer ones, for example, the Advanced Long Term Evolution (LTE-A). The demand for newer, more reliable higher capacity and high-speed information access networks is growing exponentially, especially in densely populated city areas [1]. In order to create a reliable, high capacity cellular network with wide coverage, one of the first steps is to predict how radio signals will travel in the selected environment from transmitter (Tx) to receiver (Rx). These predictions are made using different propagation model types: deterministic, empirical or half empirical. The easiest model type to apply for a selected environment is empirical because it is based on experiments and some simple calculations. Different frequency signals propagate differently in the same environment, experiments are carried out using a limited frequency range of signals
