Understanding RAN Interference in the 5G Era
Advanced RAN interference analysis is a critical component of Radio Access Network optimization, helping engineers understand how signals interact and affect performance in 5G deployments. You will learn how interference degrades performance and how controlled testing environments can help identify and mitigate these issues before live deployment
A Deep Dive into Interference and RAN Analysis
In contemporary cellular networks, interference between adjacent cells, out-of-sync timing, or improperly configured neighbor relationships can all significantly degrade throughput, reliability, and user experience. The 5G RAN environment is especially complex in Time Division Duplex (TDD) systems, where uplink and downlink share the same frequency band and depend on precise time-slot separation.
This makes proper synchronization and interference reduction techniques essential. Interference analysis is critical for detecting uplink timeslot issues and maintaining frame alignment, particularly in dense network deployments
What Orbis Systems Offers to Ensure Accurate Control and Testing
Orbis Systems leads the way in providing 5G OTA testing solutions that allow interference to be tested accurately in controlled environments. Their 5G antenna positioning solution uses absolute position sensors to keep antennas precisely aligned even after a power loss. Engineers can adjust height, distance, and polarisation in real time, enabling repeatable interference scenarios across multiple test conditions.
This level of precision is critical not only for standard testing but also for automated testing in modern telecom networks, enabling teams to systematically identify, validate, and mitigate interference before deployment
Advanced test considerations and technical terms
In radio testing, terms such as OTA (Over-The-Air), DUT (Device Under Test), and REST API integration are essential for enabling automated and repeatable test processes. Orbis Systems provides a complete solution that encompasses OTA chambers, DUT and antenna positioning, and calibration for accurate signal analysis.
The system’s ability to maintain antenna positions even after a power loss demonstrates its reliability during extended interference testing and analysis.
Driving Reliable 5G Performance with RAN Interference Analysis
Suffice it to say that knowing RAN interference analysis in the case of a 5G Radio Access Network is essential to making sure the network operates at its best and users are satisfied. Interference issues can be identified and resolved beforehand by engineers with the assistance of sophisticated OTA testing tools such as those offered by Orbis Systems.
These tools provide engineers with the precision and reproducibility they require. Get in touch with Orbis Systems to learn more about their OTA chambers and antenna positioners solutions.

Questions and Answers
Q1: What is RAN interference analysis?
RAN interference analysis is the process of detecting, measuring, and evaluating unwanted radio signals that overlap or disrupt communication within a Radio Access Network (RAN). In 4G and 5G systems, interference can come from sources such as co-channel interference, adjacent channel leakage, timing misalignment (especially in TDD networks), or external signals.
By analyzing these interference patterns, engineers can identify performance issues like low SINR, reduced throughput, dropped calls, and poor coverage, and then apply mitigation techniques such as power control, beamforming, interference coordination, or advanced scheduling.
Q2: Why is frame synchronisation critical in 5G RAN testing?
Frame synchronization in 5G RAN testing is critical to avoid uplink/downlink conflicts, reduce interference, and ensure accurate performance measurements. Without it, both real-world networks and lab test environments would suffer from unstable and misleading results.
Q3: What are the building blocks needed for an OTA testing solution?
An OTA setup usually includes a chamber that protects RF signals, an antenna and DUT positioners, calibration equipment, and control interfaces like REST APIs through which you can make test scripts automated.
Q4: How does the antenna positioning system of Orbis Systems assist in interference testing?
The system provides precise control over three parameters, such as height, distance, and polarization and uses absolute position sensors to maintain alignment even after a power loss. This ensures repeatable and consistent measurements, which are essential for reliable interference analysis.
