Aerial CUDA-Accelerated RAN Features for 5G gNB#
The 5G gNB capabilities, procedures, and interfaces have dependencies on Aerial CUDA-Accelerated RAN PHY Layer. The purpose of this section is to ensure that the Aerial CUDA-Accelerated RAN provides support for gNB capabilities, procedures, and interfaces.

Feature |
Supported |
|---|---|
Supports switching to secondary FH port within same BF3 card on primary FH port failure, transitioning C/U/S-Plane traffic from primary port to secondary FH port without stopping L1 |
