Overview
CrossFire M2RU is a digital transport platform supporting cellular and wideband public safety technologies on fibre optic cable using the CPRI protocol. The power amplifier technology adopts Digital Pre-Distortion, allowing for a significant improvement in power consumption compared with analogue technology. This platform is ideal for multi-operator multi-band deployments of cellular services into underground tunnels & outdoor coverage areas.
