Abstract

This paper discusses physical dimensions for a multi
probe anechoic chamber based (MPAC) over-the-air (OTA) setup
aiming for base station (BS) testing. The target frequency of the
simulated massive multiple-input-multiple-output (MIMO) BS
arrays is 28 GHz. The assessment is performed with two metrics.
The first metric is a new power metric based on assumptions of
a code book of fixed beams and planar waves. The second one is
the multi-user (MU) MIMO sum rate capacity. The intention
is to evaluate physical dimensions in metres with respect to
different BS array sizes. Simulation results indicate that OTA
performance of a BS array with maximum dimension of 0.15m
could be measured with a setup having measurement distance of
approximately 1m
