Wireless Works is a monthly newsletter that celebrates the success of EWA members in finding spectrum solutions, focusing on the ways that EWA has supported that success. In addition, it provides news about the private land mobile radio industry, including best practices and tips for using EWA tools, such as Cevo®.
A company that provides emergency monitoring services began experiencing “dark periods” during which it lost contact with the many units it monitors. EWA was requested to investigate possible sources of interference, and identified a large energy company, located four miles away, operating a properly licensed trunked system on an adjacent channel at 250 watts effective radiated power (ERP). The two companies had coexisted for years with no interference issues before this time. However, the energy company had recently changed to digital equipment.
