This paper presents the optimization of a General Packet Radio Service (GPRS)/Global System for Mobile communications (GSM) network. A real scenario with real base stations emplacements has been simulated with the aim of making a diagnosis of the radioelectric coverage along a train path. Afterwards, new locations for new reflex isotropic stations are proposed in order to improve the coverage where the electric field level does not exceed the sensitivity or threshold of the receiver. The antenna radiation patterns have been synthesized from the characteristic parameters, such as gain, power, directivity of the original antennas. A modified Physical Optics (PO) approximation where not only perfect electric conductors (PEC) but also dielectrics are considered is used to calculate the first reflection contribution.
