Research on Personal Area Network Interference and Compatibility Issues for Public Safety Personal Protective Equipment [open pdf - 78KB]
"First responders have access to a rapidly growing array of wireless devices to help them collect time-sensitive, multifaceted data, including tactical and environmental in-formation. Increasingly, designers are configuring these devices into wireless personal area networks (PAN) -- body-worn computer networks integrating sensors, computers and voice and data communications devices. The need to share data in real time with incident commanders and onsite responders has increased research into the potential effects of radio frequency (RF) interference. This interference can be especially pronounced when multiple PANs and other transmitting devices are operating in close proximity. Consequently, the risk is especially disruptive during large multi-agency response missions, when data collection and sharing are most critical."
