1. A method, the method comprising:
- selecting a subset of positions of antenna elements from a plurality of potential positions of antenna elements around a device under test on the basis of a simulated radio channel of a plurality of paths in an over-the-air test; and
connecting only the antenna elements in the subset and a radio channel emulator together for physically realizing the simulated radio channel.

Abstract
An emulating system of an over-the-air test comprises a radio channel emulator, a selector, a connector and a plurality of antenna elements placed around a test spot for an electronic device under test. The selector receives data on a simulated radio channel from the radio channel emulator and selects a subset of a plurality of positions of antenna elements on the basis of the data. The connector connects only the antenna elements in the subset and the radio channel emulator for physically realizing the simulated radio channel.
