Our NR RAN is 5G distributed small cell  which is a distributed 5G small base station designed based on the CRAN and ORAN standard architecture, BBU + HUBB + RU.

Product Features
Our company invested heavily and R & D personnel to successfully launch 5G NR RAN products which possess rich, open interfaces and application programming interface (API) capabilities Interoperability between components from different vendors through southbound interfaces. Develop rich applications and services through northbound interfaces to provide operators with flexible networking models and innovative business types; Accelerate software and hardware decoupling at the same time: In terms of software, the baseband unit (BBU) can be integrated with the existing software functions of the operator; In terms of hardware, through the generalization of hardware, operators can introduce cloud-based BBUs into general-purpose computing platforms to reduce equipment hardware costs.

Product innovations:

Intelligent wireless networks will be a key component of future communication networks. Signalwing gathers various aspects of R & D talents and integrates such advantageous technologies as cloud computing, big data, edge computing, artificial intelligence, and IT infrastructure with 5G Combined, the 5G NR RAN product integrates many aspects of technology and functions, and is an innovative product with absolute advantages in the current wireless communication.


  • Support X86 server platform, support all protocol stack functions of control plane and data plane, and support CU, DU and RU separation architecture.
  • Through the introduction of a Central Control Unit, on the one hand, it can achieve unified management of wireless resources and centralized control of mobility at the service level, thereby further improving network performance; on the other hand, at the architectural level, CU can be flexibly integrated When it comes to the operator's cloud platform, it can also be designed with cloudization on a proprietary hardware environment to achieve resource pooling and deployment automation, reduce OPEX / CPAX, and improve customer experience.
  • The product supports diversity reception of 4 uplink antennas, with a maximum of 4 streams per cell, and preferably supports 4 downlink antennas, with a maximum of 4 streams per cell.
