The deployment of 5G could bring a new user experience of faster data speed, higher reliability and lower latency. However, the limited propagation of mmWave in 5G would need to be supported with densified networks. Therefore, 5G mobile broadband small cells, which target for short range wireless transmission, play a big role in densified networks. This project will investigate new features to support 5G mobile broadband small cells.

The 5G mobile broadband small cell reference design for this project will support both non-standalone (NSA) and standalone (SA) 5G small cell networks with key features of (1) cell discovery; (2) sniffer based synchronization; (3) mmWave radio access; (4) mmWave digital beam tracking.

Through various business models, the technologies and reference design can be transferred to industries for different types of 5G small cell applications. A number of companies have shown strong interests in collaborating with ASTRI and adopting our technologies to be developed from this project. Initial customers, including network infrastructure equipment vendors Wireless Systems Solutions (WSS) and HK Shiju, have already committed to support this project. Many other companies such as Casa Systems, Telrad, Contela, and Anktion have approached us for potential technologies licensing from this project.
