- Complex DU Processing
- Limited MIMO Layers
- Inefficient 7-2x Split
Tech Features
- Reduced Front-Haul Load
- Distributed CSI-RS Processing
- Simplified O-DU/RU Compute
- Scalable Massive MIMO
- Optimized Sequence Mapping
- Orthogonal Weight Superposition
Target Audience
- O-RAN Equipment Vendors
- 5G Network Operators
- Front-haul Infrastructure Providers
- Research & Development
- Centralized RAN Deployers
