Summary:
This report presents the results of the evaluation conducted by ANACOM between May and July 2011 on the quality of voice and video-telephone services and of coverage provided by the GSM and WCDMA (UMTS) networks of OPTIMUS, TMN and VODAFONE in the main urban centres - Ponta Delgada, Angra do Heroísmo and Funchal - and along the main roads of all islands - Corvo, Faial, Flores, Graciosa, Pico, S. Jorge, S. Miguel, Santa Maria, Terceira, Madeira and Porto Santo - of Portugal's Autonomous Regions of the Azores and Madeira. The study was conducted with the analysis of technical parameters which reflect the perception of quality from a consumer standpoint.

GSM - Global System for Mobile Communications: 2G mobile telephone. Standard used in 2G digital mobile communication systems in Europe and Asia which specifies how data is encoded and transferred through the spectrum. GSM digitalises and compresses data related to a connection, transmitting it through a channel together with that of other users, using time-division multiplexing.
QoS - Quality of Service: Term used for a set of parameters which characterise the performance of a circuit, a network or a service.
UMTS - Universal Mobile Telecommunications System: One of the 3G mobile communications systems which will be used, particularly in Europe, and which is integrated in a much larger family (IMT-2000).
