5G Economics Requires “Small Cell + MEC”Traditional Macro architecture could cover 80% of the outdoor space while leave indoor and some outdoor black-hole uncovered.
5G era, due to its spectrum characteristics, through MEC, Small Cells will carry 80% of total traffic, cover 80% indoor and 20% outdoor space

Baicells M-RAN indoor solution for sub6GHz
uBaicells M-RAN solutions are based on GPP and FPGA HW platforms, and support RAN virtualization to provide carrier grade solution with most flexibility
uSpecifically for indoor, support SW architecture of CU/DU/RRU, while co-platform for CU, DU, and MEC including local CN functionalityl Carrier grade GPP server with FPGA
acceleration for CU/DU and MECl Carrier grade timing support, such as GNSS,
OCXO, 1588V2 GM, and SyncEl Computing power scalable via
cloudification upon specific scenariol PicoExtending unit supports multiple
modes including CPRI and eCPRIl pRRU could be used as O-RU
