Measurement Uncertainty, Channel Simulation, and Disturbance Characterization of an Over-the-Air Multi-Probe Setup for Cars at 5.9 GHz

Summary, in English

Over-the-air multi-probe setups provide an efficient

way to characterize the performance of today’s advanced wireless

communication systems. In this paper the measurement uncertainty

of such a setup using a car as a test object is characterized

through three experiments: measurement system analysis, channel

sounder measurements, and probe coupling measurements.

Four issues were in focus for the analysis; precision, realization

of the wireless communication channel, coupling between the

probes, and the influence of the test object size. The analysis

shows that a large test object such as a car in an over-the-air

multi-probe ring will affect the measurement uncertainty, but

only to a small degree. The measurement uncertainty expressed

as expanded uncertainty was below +/-1dB, a level that would

not violate best practice total uncertainty levels for comparable

over-the-air methods.
