High-Power Remote Radio Unit (mRRU)


The HELIOS High-Power RRU is a digital transport platform supporting cellular technologies on fiber optic cable using the CPRI protocol. The power amplifier technology adopts DPD (Digital Pre-Distortion), allowing for a significant improvement in power consumption compared with analogue technology. This platform is ideal for underground tunnels & outdoor coverage deployments of cellular services.


  • High power output: 2T2R MIMO, up to 40W per port
  • Massive MIMO antenna array of 2 x 2, external antenna
  • DPD, CFR, and AGC for better sensitivity and communication quality
  • Low modulation EVM, ALCR, and spurious emission
  • High uplink sensitivity
  • Frequency band by SKU
  • Support Cascading
  • Support FDD & TDD
  • Low Power consumption and high efficiency
  • IP-65 Ingress protection
