M3RU-L stands for Medium Power Remote Unit 3.0 (Low Frequency), which is a medium-power remote unit in SUNWAVE’s 3rd-generation CrossFire platform system (CrossFire 3.0). It connects to the A3/E3 via fiber optic cables and converts the digital signals received from the A3/E3 into RF signals before transmitting them through an antenna. Each M3RU is equipped with an 8-band combiner, 7 low-frequency modules, and reserves 1 interface for external 5G signals. It supports multiple frequency bands and flexible networking, and is ORAN-compatible with a firmware upgrade.
