Distributed wireless environmental noise monitoring systems

Kurt Veggeberg

Wireless technology extends the concept of PC based data acquisition beyond the limits of cables and wired infrastructure for new remote or distributed measurement applications. This is an overview of wireless networking basics and how to deploy reliable wireless measurement in a variety of outdoor or harsh environments for reliable and secure data acquisition systems. Case applications of distributed outdoor noise monitoring systems will illustrate networking layers and topologies for specific applications using IEEE 802.11 networks for reliable and secure wireless data acquisition systems. One example is a 10-node autonomous, distributed wireless monitoring system placed in various locations throughout the Historic Center of Mexico City. It takes permanent measurements of the noise levels and streams the data back to a main monitoring station every five minutes along with the measurements of noise produced during takeoff at the International Airport of Mexico City. Another example from France called SAVE (Surveillance of Acoustics and Vibration in the Environment) is a noise and vibration management system for construction site managers. It is based on multiple laptop based front ends placed throughout a construction site and connected wirelessly to a central supervisor for continual monitoring and reporting.
