LIONS 5G O-RAN products support 3GPP R15 which emphasizes eMBB characteristics. In this PoC, customer applications includes AR for material sorting and high definition video transmission for AGV navigation. The factory is located in north Taiwan and is owned by a world class company.
LIONS implements DDDSU frame structure first as it performs better in downloading application. In August, product development reaches reliability and stability targets that end-to-end downloading and uploading throughput is recorded. In this stage, performance is still not optimized and more improvements are to be introduced.
LIONS 5G SA O-CU and O-DU is tested with 5GC (5G Core Network) from various vendors. Polaris is a mainstream 5G testing platform 5GC. While III (Institute for Information Industry) is a Taiwan government supported research tank for software and information technology. And QCT (Quanta Cloud Technology) is world’s No. 1 infrastructure provider for cloud and data center market. End-to-end connection with popular 5G mobile phone is also carried out.
There are many radio shielding objects in this case. To ensure performance, the arrangement of O-RU should be carefully tested and verified. We help customer to evaluate throughput requirement of remote surgery. This trial is exercised in a hospital in middle Taiwan.
LIONS decides to develop SA technology and products after communicating with customers. 5G NSA product development is suspended. And following development focus on 5G SA O-RAN technology. Target product categories are outdoor O-RU and integrated O-CU and O-DU on COTS server.
LIONS’ NSA BBU cooperates with 4G LTE EPC core network. The first implement follows O-RAN standards and O-CU and O-DU definition. The package is running on COTS (Commercial off-the-shelf) server. LIONS O-CU and O-RU finishes Interoperability test with CISCO 4G EPC in a short time. Minor problems are solved with minimum modification to BBU.
Upon accomplishing 2G/3G/4G products R&D and business in 2018, LIONS team members were focusing on the O-RAN 5G technology. We believed the 5G open standard will bring another wave of Taiwan success in standard-based industrial business. The team rolled sleeves and went working on it. Lions 5G O-RAN gNB architecture and HLD were done before establishing LIONS companies in 2019 to carry the mission.
