This paper illustrates "MisuraInternetMobile", a national project which has the aim to monitor the QoS performance provided by Italian mobile network operators. This is obtained through measurement campaigns performed on the entire national territory. The main purpose of the project is to give users the possibility to verify the performance that can be achieved in different areas by each mobile network. Furthermore, the large amount of data collected during the campaigns allows many in-depth analyses about mobile broadband access. In this regard the work also reports some results obtained from dynamic measurements aimed to investigate the impact of mobility on the performance and QoS delivered to users.
