ANRITSU CORPORATION announced that it has jointly verified AI-based antenna optimization technologies with SK Telecom, South Korea’s leading mobile network operator, Pohang University of Science and Technology (POSTECH), and Bluetest of Sweden.
Using Anritsu’s Radio Communication Test Station MT8000A and Universal Wireless Test Set MT8870A, the team captured real?world MIMO measurement data in typical user environments. AI?driven analysis and optimization confirmed that antenna performance can be significantly improved under realistic conditions.
The verification analyzed antenna behavior using throughput and ECC (Error Correlation Coefficient) data collected from real user scenarios, including free?space use, handheld operation, and head?proximate situations. By covering a range of grip conditions, it quantitatively assessed performance variations under time?varying RF environments.
Using AI, the team modeled RF performance differences across various antenna tuner states and automatically identified the optimal antenna?switching configuration. This enabled dynamic antenna optimization that maintains communication quality while adapting to real?world conditions.
Measurement?driven results showed meaningful throughput gains across different user scenarios in an 8Rx (eight?receive?antenna) setup. In a 4Tx (four?transmit?antenna) configuration, throughput improvements of more than two times were observed.
Verification overview
The team demonstrated an AI?based antenna optimization workflow grounded in real Over?the?Air (OTA) measurement data.
The process included:
- Analyzing RF performance variations across user scenarios and tuner states
- Comparing power and performance characteristics for each antenna path
- Deriving optimal switching states from throughput and ECC data
- Validating performance gains through AI?based analysis of measurement data
This approach moves beyond traditional static, antenna?design?centric evaluation, enabling data?driven optimization that reflects actual environmental conditions.
