5G Small Cell O-DU Platform
O-RAN Alliance has defined reference distributed architecture to enable next generation RAN infrastructure, consisting of DU and RU. CIG has developed a series of hardware platform specially targeted for 5G small cell deployment for indoor 5G coverage and capacity enhancement. The platform is fully programmable based on general purpose ARM Processor and FPGA. A 3-tier architecture is adopted to carry out the gNB functionality, i.e. SC-60 O-DU, SC-70x O-RU and SC-640 O-Bridge. The number of each component can be flexibly configured to meet various application demands.
The O-DU is the center of the platform. Partial or all 5G air interface functions can be implemented within the O-DU, including L1, L2 and L3, according to the networking requirements.
