| Abstract [eng] |
This work concerns about the signal propagation models used for the existing 4th Generation (4G) of cellular networks known as Long Term Evolution Advanced (LTE - A) and the comparison between UMTS technology. LTE - A is recognized as ITU 4G technology that has yet been used to provide public services. Therefore, there are a sufficient number of the issues, including those relating to the path losses, which are not solved yet. The signal propagation for microcells based on building heights and distance from base station, plays a very significant role in planning of any wireless communication systems, is examined. The experiments were carried out in an urban area. The “Huawei LTE CPE Modem E5186 – 22a” was used to carry out the experiments in the urban area. There were measured the signals’ path losses from two mobile network base stations depending on buildings highs and distances to them. The “R&S®FSH4 View Version 2.20” spectrum analyzer 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 and the results proved the new propagation model with accuracy ~97.8 %. |
