Abstract
An apparatus for measuring over-the-air (OTA) wireless communication performance in an automotive application of a device under test arranged on or in a vehicle is disclosed. The apparatus comprises a chamber and a platform for supporting the vehicle within the chamber. The platform is a rotatable platform that can rotate the vehicle, and the floor is inwardly reflective, and optionally covered with a top layer to resemble asphalt or other road covers. In one embodiment, the chamber is a reverberation chamber, simulating a multi-path environment, and preferably a rich isotropic multipath (RIMP) environment. In another embodiment, the chamber has inwardly absorbing walls, simulating a random-LOS environment.
Claims36
An apparatus for measuring over-the-air (OTA) wireless communication performance in an automotive application of a device under test arranged on or in a vehicle, comprising:
- a chamber defining an internal cavity therein, and
- a platform for supporting the vehicle,
- wherein the chamber is adapted to enclose the platform,
- wherein the platform is a rotatable platform that can rotate the vehicle, and
- wherein the floor of the chamber is inwardly reflective, and optionally covered with a top layer to resemble asphalt or other road covers.
A method for measuring over-the-air (OTA) wireless communication performance in an automotive application of a device under test arranged on or in a vehicle, comprising:
- providing a chamber defining an internal cavity therein;
- arranging the vehicle within the internal cavity;
- and
- measuring over-the-air wireless communication performance while horizontally rotating the vehicle intermittently or continuously during the measuring.
