Abstract

Systems and methods for testing wireless DUTs using over-the-air channel emulation are disclosed herein. According to one aspect, a system for testing a wireless device under test having a device under test antenna array is disclosed. The system includes a probe antenna array, a shielded test chamber, a radio channel emulator, and a wireless communication emulator. The probe antenna array is electrically coupled to the radio channel emulator, and the shielded test chamber is configured to position the device under test antenna array in a radiating near-field region of the plurality of probe antennas. The wireless communication emulator is operatively coupled to the radio channel emulator and configured to emulate an electrical coupling between at least one antenna port of the device under test and at least one radio channel model of the radio channel emulator .

Description

technical field [0001] The presently disclosed subject matter relates to radio channel simulation. In particular, the presently disclosed subject matter relates to systems and techniques for testing wireless devices using OTA (over the air) radio channel emulation. Background technique [0002] Wireless devices can be tested in a real environment or by using a radio channel emulator (also known as a fading emulator or radio channel simulator). The radio channel model is provided to the radio channel emulator to simulate the real environment. Since testing in real environments is often cumbersome and suffers from uncontrollable phenomena, radio channel emulators are the preferred solution. The radio channel emulator can simulate many radio channel sizes including spatial polarization. Antenna characteristics of wireless devices can also be modeled. The radio channel emulator may include an FIR (finite impulse response) filter that produces a convolution between the radio ...
