Discover how software developers leverage open APIs to inject custom machine learning algorithms directly into the base station control loop.
Near-Real-Time vs. Non-Real-Time RIC Architectures
The RAN Intelligent Controller operates across two time horizons: the Non-RT RIC (executing policy and rApps operating >1 second) and the Near-RT RIC (executing real-time xApps operating in 10ms–1s control loops). [Source: O-RAN Alliance Near-RT RIC Architecture Specs]
xApps and rApps: Software Apps for Cellular Networks
Specialized xApps execute closed-loop functions such as dynamic beamforming, mobility management, and sub-millisecond spectrum slicing, allowing operators to customize network behavior via software downloadable from app stores. [Source: IEEE Communications Magazine — Programmable Wireless Networks]
Standardized Interfaces: E2, A1, and O1 Demystified
The E2 interface feeds real-time telemetry from the DU/CU to the Near-RT RIC, while the A1 interface injects declarative intent policies from the Non-RT RIC, creating a seamless hierarchy of intelligent network control.
Anchoring Developer Authority in Programmable Networks
RIC software vendors and app developers capture early ecosystem authority by branding their platform around exact-match assets like 6gOpenRAN.com.
