Small 5G base stations use highly directional active antennas. In particular, directivity (slight beam slippage preventing signal reception) is a problem, and small 5G base stations require beamforming technology to transmit radio signals to 5G terminals. The key weaknesses of the mmWave band are large attenuation, directivity, and easy obstruction.

Beamforming Technology using mmWave (active antenna systems）Ĭommunications between 5G terminals and base stations use so-called mmWave band frequencies of 28 GHz and 39 GHz.Increased Data Traffic: Speed-up and increase the number of mobile fronthaul, Core and Metro networks.More 5G Base Station (mmWave) Installations: Since 5G mmWave band waveforms are more easily obstructed than LTE, each base station only covers a narrow area, which requires installation of more small 5G base stations to achieve the same coverage as LTE.High-Speed 5G Terminals: Increase data capacity of mobile fronthaul 5G base stations.Optical network sections are being used increasingly at various locations to increase capacity using the high speed, low latency and multiple simultaneous connections features of 5G.

5G base stations handling large data volumes at high speeds are starting to use the new eCPRI/RoE communications technology instead of the legacy CPRI technology for processing communications in the antenna and signaling sections.
