The Intelligent Energy Sustainability Optimiser rApp helps mobile operators understand and reduce energy consumption across the radio access network without compromising service performance. Built for automated, data-driven network operations, the solution analyzes energy and performance information to identify inefficient sites, equipment, and operating patterns. It supports targeted optimization actions, ongoing measurement, and sustainability reporting across complex RAN environments. The brochure explains how intelligent energy management can lower operating costs, improve visibility, and advance network modernization and carbon-reduction goals.
