USING THE MOBILE NETWORK FOR TROPOSPHERIC DUCTING DETECTION

Abstract

The radio communications systems are affected by abnormal refractive conditions of propagation, which cause affectations to their availability. The regularity of appearance of the previously mentioned phenomena in our climatic area is very high, as well as the incidence of the degradation of mobile communications services. The objective of the present work consists of the possibility of detection of anomalies in the gradient of the refractive index of the troposphere using RTWP (Receive Total Wide Band Power) data is founded. The analysis is based on a statistical correlation study between the maximum daily level of interferences in RTWP base stations, reported by UMTS (Universal Mobile Telecommunications System) technology cells, and two sources of tropospheric duct parameters. In the first case, Key West's sounding station reports are used; in the second place, the data of re-analyses the ERA5 system. In the same way, these results correlate with the reports of the detection of external operator's signals compiled by the National Center of Spectrum Control. The results of the comparison of interference signals received, and tropospheric ducting detection are satisfactory and prove the capacity of the network to reflect the phenomenon under investigation.
