The equipment, originally, was developed to be used in fixed environments, so it was adapted so that it could be used in conditions of mobility. From the Mobile Measurement Reports (MMRs) RF coverage and the handover process are analyzed. The MMRs enable the identification of the serving cell and the list of the closest neighboring cells monitored by the mobile. This work analyses only data referent to the serving cell and the two closest neighboring cells. Inter-cell and intra-cell handovers are identified. The frequency planning and quality of service offered by the network related to the regions are discussed as well / Esta disserta??o apresenta a aplica??o de um aparelho port?til, PlugData MG100G, equipado com um m?dulo celular, para an?lise de cobertura de radiofreq??ncia em uma rede GSM na cidade de Jo?o Pessoa - PB em quatro regi?es distintas. O equipamento, originalmente, foi criado para uso em ambientes fixos, e para isso, tornou-se necess?ria sua adapta??o para que fosse utilizado em condi??es de mobilidade. A an?lise de RF ? feita atrav?s do Mobile Measurement Reports (MMRs) que s?o usados com prop?sitos de avaliar o handover na rede. Por interm?dio do Measurement Reports ? poss?vel identificar a c?lula que serve o m?vel e uma lista de c?lulas vizinhas mais pr?ximas monitoradas pelo pr?prio m?vel. Neste trabalho s?o analisados apenas os dados referentes ? c?lula servidora e ?s duas c?lulas vizinhas mais pr?ximas. Verificam-se tanto handovers inter c?lulas (entre c?lulas) como handovers intra c?lulas (no interior das c?lulas). Atrav?s dos resultados obtidos pode-se fazer uma an?lise em rela??o ao planejamento de freq??ncias criado para as regi?es onde as medidas foram realizadas e ? qualidade de servi?o oferecida pela rede
