Abstract:

Wireless technology extends the concept of personal computer 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. Examples 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. These include a distributed, synchronized data acquisition system for the extended measurement of sonic booms and a portable noise and vibration management system with multiple front ends connected wirelessly throughout a construction site to be compliant with local regulations and contractual obligations for noise and vibration levels.
