Nokia's ReefShark silicon cuts massive MIMO antenna size and power consumption

Nokia unveiled its ReefShark 5G chipsets for radio frequency (RF) units such as the radio used in antennas. The chipsets, which were developed in-house, significantly improve radio performance resulting in halving the size of massive MIMO antennas. Nokia says its ReefShark chipsets also reduce power consumption in baseband units by 64%, compared to current technology.


The ReefShark chipsets comprise:

  • ReefShark Digital Front End for LTE and 5G radio systems supporting massive MIMO
  • ReefShark RFIC front-end module and transceiver: massive MIMO Adaptive Antenna solution
  • ReefShark Baseband Processor: All-in-one compute heavy design, capable of supporting the massive scale requirements of 5G. This is the brain power of baseband processing.

The ReefShark chipsets for compute capacity are delivered as plug-in units for the commercially available Nokia AirScale baseband module. The new plug-in units triple throughput from 28 Gbps today to up to 84 Gbps per module. Additionally, AirScale baseband module chaining supports base station throughputs of up to 6 terabits per second. Nokia said this level of performance will allow operators to meet the huge growing densification demands and support the massive enhanced mobile broadband needs of people and devices in megacities.

Nokia also announced that it is working with 30 operators using ReefShark and will ramp up field deployments during the third quarter of 2018.

Henri Tervonen, CTO of Nokia Mobile Networks and head of R&D Foundation said: "With ReefShark, Nokia has created a clear competitive advantage. Its combination of power, intelligence and efficiency make it ideally suited to be at the heart of fast arriving 5G networks."
