The original proposal of Advanced Metering Infrastructure based on short-range communication (wM-Bus) is suggested for the continuous monitoring of Particulate Matter within Smart Cities. A prototype of water meter equipped with a low cost off-the shelf PM sensor has been developed as remote node to be adopted in the radio Local Area network. Result of the metrological characterization against the quality requirements of the PM measurement according to European regulations as well as the simulation of a typical Smart Metering scenario in terms of communication performance confirm the feasibility of the proposed AMI for an effective adoption within urban areas
