Over-the-air testing in a virtual electromagnetic environment

Tests/measurements:

• Mobile communication systems (LTE, LTE-A, UMTS, 5G)
• Global navigation systems
• Industrial communication systems
• Cognitive radio systems
• C2I (car to infrastructure), C2C (car to car) systems

Especially suited for:

• Multi-antenna systems
• MIMO (Multiple Input Multiple Output) equipment
• Direction finders
• Communictation systems with integrated antennas
• Beam forming antennas
• Controlled-reception-pattern antennas (CRPA)

Virtual electromagnetic environments:

• Realistic multipath propagation environments including spatiotemporal characteristics of the electromagnetic field
• Mobile scenarios (incl. high-speed)
• Arbitrary radio environments and application scenarios
• Coexistence and interference scenarios

Advantages:

• Reproducibility compared to field tests
• Cost-efficient
• Available at any time and weather independent
• No interference to licenced users (shielded chamber)
• Virtually any location/scenario/prognostic testing in still unavailable bands or uncommissioned systems, incl. “whatif” scenarios
• Non-destructive assessment of integrated multi-antenna system performance
