CUESTA RAMIREZ, Jhouben Janyk; OROZCO GUTIERREZ, Álvaro Ángel  e  ALVAREZ LOPEZ, Mauricio Alexánder. Analysis of the expansion of a GSM network using Gaussian Processes. Iteckne [online]. 2013, vol.10, n.2, pp.149-157. ISSN 1692-1798.

The expansion plan of a Global System Mobile (GSM) network requires the analysis of some important variables known as key performance indicators (KPI) on the network. Network operators have tools for analyzing a KPI behavior on a particular network cell. This paper proposes a tool that illustrates graphically the behavior-in-time of a KPI in a whole geographical zone (including cell positions). A Gaussian process repressor is used over a real data set and time-space inference is performed. Finally we observe how a particular region presents high-KPI values most of the time. This alerts the network operator for including a solution in the formulation phase of the network expansion plan.
