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.
