CrossFire N3RU

N3RU stands for Nano Power Remote Unit 3.0, which is a nano-power remote unit of SUNWAVE’s 3rd-generation CrossFire platform system (CrossFire 3.0). It connects A3/E3 through fiber optic cables and converts the digital signals received from A3/E3 into RF signals before transmitting them through an antenna. One N3RU supports 8 channels, with a single channel capable of supporting a 300 MHz bandwidth, multiple frequency bands, and flexible networking. It has two versions: external antenna type and internal antenna type. It can support ORAN by upgrading its firmware.
