Abstract

We examine interference and coexistence testing issues, test methods, and the need to update and develop new test methodologies related to the use of wireless devices in critical infrastructure systems. A case study on interference is presented along with measurements of the ambient electromagnetic environment near banks of electricity meters in a high-rise apartment building. We discuss the challenges to characterizing complex electromagnetic environments, emulating these environments in the laboratory, and designing test methods that adequately evaluates the ability of a device to perform in that environment. We also discuss current electromagnetic compatibility and coexistence standards and suggest future research that is needed to update or develop interference and coexistence test methods for wireless devices and systems.
