Propuesta para la ampliación de cobertura LTE en zonas suburbanas mediante la implementación de un sistema radiante en la banda APT700.

Abstract

In this degree work, a study was carried-out whose purpose was to develop a proposal for an LTE radiant system that offers better coverage performance in suburban areas, which guarantees stability in packet switching services and coexists with deployed LTE physical systems. For this purpose, the APT700 band was selected as the operating frequency and a standard configuration was set for the physical and radiation parameters for a cell. We interacted with LTE systems (AWS / APT700) through tasks established in UE for PS services in order to establish criteria and comparisons. The levels of RSRP, RSSI, RSRQ, CQI, SINR were collected by means of RF engineering instruments (scanner, UE, GPS, antenna). Accuver professional software was used: for reading the XCAL air interface, and for the XCAP data post processing. The results show that there is a notable improvement in the distribution of RSRP levels, greater coverage footprint than AWS, stability in packet switching and acceptable channel quality estimates. Therefore, it is concluded that the LTE operation over the 700 MHz band has positive results for the deployment of coverage and advantage in suburban environments, becoming the best option for national coverage.
