Abstract
Radiated testing of massive multiple-input-multipleoutput
(MIMO) devices in fading radio channel conditions is
expected to be essential in development of the fifth generation
(5G) base stations (BS) and user equipment (UE) operating at or
close to the millimetre wave (mm-wave) frequencies. In this paper
we present a setup upgrading the multi-probe anechoic chamber
based system designed originally for 4G UE.We describe methods
for mapping radio channel models onto the probe configuration
and discuss the differences to the former 4G case.We also propose
metrics to assess the accuracy of the test setup and find key design
parameters by simulations. The results with the utilized channel
models indicate that at 28 GHz up to 1616 planar arrays can
be tested with range length of one meter and with at minimum
eight active dual polarized probes.
