5G Technology world will host a discussion of Open RAN technology on June 16, 2021. Register here to view the recorded webinar.
Open radio access networks (Open RAN) are all the rage in the 5G community and engineers should know how they work. Open RAN rips open the proprietary baseband units (BBU’s) that connect base-station radios to digital networks. Breaking the BBU into three parts — Radio Unit (RU), Distributed Unit (DU), and Centralized Unit (CU) — frees network operators from proprietary systems. Operators can then choose software suppliers for each unit, potentially running everything about the radio itself on COTS hardware. This open system also lets operators choose the supplier that best need its needs. Open RAN brings forth opportunities for niche functions with on the RAN that can’t happen with proprietary BBUs.
This panel of open RAN experts — covering software, network equipment, and test — will break down the technology in engineering terms, giving engineers insight into the technology. The panel will cover how open RAN disaggregates functions formerly encapsulated into proprietary boxes called baseband units.
The discussion takes place on Wednesday, June 16, 2021 at 11:30 ET, 8:30 PT, 16:30 UK, 17:30 CET.
Opening the RAN into RUs, DUs, and CUs offers flexibility in network design and opens the door for new applications and functions. This openness brings interoperability concerns. Industry organizations are working on standardizing the interfaces between units. Still, the opportunity for interoperability issues can hinder Open RAN adoption. The good news is that the telecom industry knows how to deal with interoperability. This panel will discuss:
- The radio. As the gateway to the network, 5G radios must connect seamlessly to the distribution units. Some radio functions, particularly at baseband, and reside in the radio or further up the network. That leads to tradeoffs and decisions on where to place these functions.
- The software. How does a distribution unit work? How does a centralized unit work? Open RAN software providers will discuss more than what goes in and what comes out. They won’t treat the open units as black boxes.
- Interoperability. This will require testing of the interfaces between units. Someone has to verify standards compliance and test for interoperability. The test industry will be the arbiter.
- Testing. The panel will look at baseband for the radio unit. Do the radio units, distribution units, and centralized units function as intended? Who will perform these tests?
