Ceragon Networks, a provider of high-capacity, 4G/ LTE-Ready wireless backhaul networks, has announced a new product in its FibeAir RFU (Radio Frequency Unit) solutions range. The Green Mode RFU-HP makes for unique, energy-efficient 1Gb IP Trunk radio implementations. Featuring an adjustable power mode the Green Mode RFU-HP can reduce radio link power consumption by as much as 30% compared with existing solutions. The new RFU-HP is combined with Ceragon advanced FibeAir IP-10 platforms, for a complete, feature-rich IP solution with an unmatched, low total cost of ownership.

A critical design issue for current wireless networks is the development suitable architectures that can efficiently reduce power consumption, thereby increasing the operational lifetime of the network, while cutting operational expenditure. Ceragon’s Green Mode RFU-HP offers automatic control of both the power consumption as well as the transmission power, ensuring that no excess energy is used while the network operates in “steady state.” Under fading conditions the power is automatically increased to compensate for signal loss and to ensure the link continues to meet the required performance level.

Ceragon’s new radio system can provide additional and significant power savings across an entire telecommunication network, without compromising performance and availability. In addition, the New RFU-HP comes with the following unique capabilities:

  • Highest available transmit power – Supporting transmit power of up to 32dBm, both in split and all indoor configurations, the Green Mode RFU-HP offers unmatched performance, extending wireless links over longer distances with enhanced availability. This feature also allows carriers to use smaller, less costly antennas without compromising the link’s reach or performance.
  • High capacity – Operating in any standard channel bandwidth up to 56 Mhz, Green Mode RFU-HP delivers up to 500Mbps on a single channel, and up to 1Gbps using cross polarization Interference Canceller (XPIC).

Additional Power and Cost Saving Benefits

  • All-outdoor Trunk IP Networks – RFU-HP can be deployed in combination with Ceragon’s advanced FibeAir IP-10 solutions family in all-outdoor configurations. Allowing for zero footprint deployments, the combined solution can scale up to to 5 Gbps of guaranteed traffic. Requiring no heating or cooling devices, it helps operators to achieve additional power savings.
  • Support for asymmetric transmission – Unlike competing radio systems, RFU-HP can be used in asymmetric mode (higher bandwidths downstream, lower bandwidths upstream). This allows operators to design smarter network architectures with lower equipment costs and reduced power consumption across the entire network.
  • Adaptive Transmit Power & Adaptive Coding and Modulation (ACM) – Ensuring that each microwave radio is automatically optimized to provide the best performance under changing weather conditions. Adaptive transmit power is used to lower the signal output power when environmental conditions are good in order to reduce power consumption and network interference. ACM is a technology that allows the wireless link to adjust itself to changing weather conditions in order to support several types of availability for different types of service.

Ira Palti, President and Chief Executive Officer of Ceragon, commented: “By reducing the cost and power requirements of wireless long haul solutions, Ceragon enables operators to serve remote communities profitably.”
