Which statement is true about Radio Resource Management (RRM)?
RRM operates as two parallel systems. The global optimization system is cloud-based and analyzes long-term statistics and baselines across an entire site, applying channel and power changes only once per day, typically during a low-usage window (around 2:00–3:00 AM local time), to avoid disrupting users during business hours. In contrast, the event-driven (local) RRM system runs continuously at the access point level and reacts immediately to real-time triggers, such as radar detection or capacity service-level deviations, rather than operating on a fixed hourly or daily schedule. This makes the statement that the global optimization system runs once a day the accurate description of RRM behavior.
