One of our demonstrations at MWC17 is with ASTRI, the Hong Kong Applied Science and Technology Research Institute. This organization has the mission of enhancing Hong Kong's competitiveness in technology-based industries through applied research.

Astri demo description

Our collaboration has resulted in a live Centralized Radio Access Network (C-RAN) virtual cell demonstration running on a MaxCore™ platform, showcased in the Sunnada booth (5G70).

The demonstration shows live video streaming and real-time data traffic on a high density wireless network deployed with ASTRI's C-RAN virtual cells. Artesyn's MaxCore platform supports the Baseband Unit (BBU) pool processing - connected to Sunnada Remote Radio Units (RRUs), enabling Joint Transmission (JT) and Joint Reception (JR). The mobility of the terminals is also tracked inside the BBU pool to avoid handover.

ASTRI's C-RAN virtual cells reference design is based on the Intel X86 CPU architecture and can use Network Functions Virtualization (NFV) frameworks. The design supports LTE release 9 and above, and is scalable to support up to 96 LTE cells. It also supports flexible partitions of BBU pool and RRUs trading off network latency and cell-coordination requirements.

The design also supports live migration, where the system can flexibly configure the processor resources for different traffic loads. The unused processor resources could support other applications such as Mobile or Multi-Access Edge Computing (MEC). This design could also support High Availability (HA) by using the Artesyn MaxCore™ HA platform.
