Hello Experts.
Why Is O-RAN Facing Headwinds?
What are the key challenges holding it back?
Bandwidth and Inter-compatibility
- Clocking and synchronization challenges between the O-RU and O-DU — this link is highly latency-sensitive.
- Due to packet bottlenecking on the DU side, TTI stretches are eventually observed.
Interoperability Issues
- Vendors such as Nokia and Ericsson are reluctant to face these challenges directly.
- Otherwise, their proprietary T-RAN solutions and OEM vendors risk significant financial losses.
It seems that both Mavenir and Radisys are no longer in the Open RAN competition.
They are still operating, but have laid off a significant portion of their employees. They continue to work with Dish, JMA, Charter, and Deutsche Telekom.
- Another major challenge involves Intel and AMD CPUs - now the industry is waiting for NVIDIA to step in with their GPUs.
