In order to participate more activities of O-RAN community, LIONS is now a member of O-RAN Alliance. LIONS’ end-to-end RANathon O-RAN solution, including O-CU, O-DU, FHGW, and O-RU, is compatible with O-RAN standards. It is also suitable for operator or private 5G applications. We are eager to develop products based on customer’s request.
Open5GS is a popular open source 5G core network software for many deployments. Tested products include LIONS RANathon O-CU and O-DU, RANathon RS8601 Indoor O-RU, and RANathon XG8600 Fronthaul Gateway. 5G UE can connect to Open5GS via the RAN network successfully with good performance. Reader can check the list in Open5GS GitHub.
LIONS RANathon 5G O-RAN end-to-end products successfully connect to Nokia and Ericsson, separately, and finish all related IoT items. The IoT last a few days due to hardware connection issues. No significant obstacle found in the process. We also log performance data for up-link and down-link communication.
“RANathon” is a compound word of RAN and Marathon. Naming process includes internal nomination, propoganda and general election by all LIONS team members. The official name is “LIONS RANathon 5G O-RAN product line”.
LIONS O-CU and O-DU can smoothly connect to open source Open5gs 5GC. The performance is enough for PoC, evaluation, and small scale network. Setting up Open5gs and connecting to LIONS O-CU and O-DU takes just a few hours work. Simple and easy!
For many early 5G private networks, implementation is indoor to avoid spectrum conflict. LIONS RS8601 indoor O-RU supports 4T4R, 250mW per channel, and stylish industrial design. It supports wall and ceiling mounting. Also there is built-in unidirectional antenna for easy indoor deployment.
DSUUU frame structure performs well in uploading scenario, thus is suitable for hi-definition video uplink transmission, DSUUU frame structure. Massive video up-streaming is popular in private 5G applications. As of now, the end-to-end performance of LIONS gNB is recorded as:
DL MIMO layers: 4
UL MIMO layers: 2
|Downlink 256QAM||Uplink 64QAM|
|DDDSUUDDDD (Japan TDD-Sync)||1.57Gbps||165Mbps|
|DDDSUUDSUU (Japan Semi-Sync)||916Mbps||331Mbps|
Responded to customer’s requests, LIONS O-CU and O-DU can support additional NR frame structures. DDDSUDDSUU is adopted by some mobile carriers. And private 5G customers in Japan use DDDSUUDDDD and Semi-sync DDDSUUDSUU frame structures . These frame structures support various scenarios. LIONS finish the upgrade in a short development and integration time.
Considering coverage is the initial priority for many private 5G customers, LIONS has Fronthaul Gateway (FHGW) in its product line. FHGW, coupled with BBU, can link up to 8 O-RUs per unit simultaneous. Also FHGW can be stacked with another FHGW that a cell can support max. 16 O-RUs for coverage enhancement. FHGW can support remote site deployment for a cell.
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.
