Automotive Test Chamber

The rapid development of connectivity in the automotive industry and the trend towards autonomous driving is leading to a demand for premium wireless performance. With the Automotive Chamber, KYOCERA AVX can support customers by validating the connectivity on the roughest conditions when the antennas are integrated within the vehicle.

The Automotive Chamber is a semi-hemispherical anechoic chamber capable of testing wireless devices from 600 MHz to 6 GHz. The system consists of a rotating platform of 4.5m diameter, supporting vehicles weighing up to 2.5 tons, and an arc of 10 dual polarized horn antennas. The size of the chamber is 9.6 meters length, 8.6 meters wide and has a height of 6 meters. The automotive chamber is located at the antenna design center in Nice (France), in the technology park of Sophia Antipolis.

​The chamber is operating using the complete antenna software suite, including:
• Antenna Measurement (Measurement Control and Data Acquisition)
• Antenna Viewer (Post-processing and tabular/graphical data output)

Different frequency ranges can be measured in the automotive chamber
(passive measurements for all frequencies and active measurements for cellular bands):
• Cellular from 700MHz to 6 GHz (3G, 4G, LTE, 5G, NB-IoT, LTE-M)
• Satellite (GNSS)
• Wi-Fi & BLE
• DSRC / V2X 

*For RADAR frequencies, refer to mmWave Chamber

Although the principal DUTs (Devices Under Test) are vehicles, with the increase of connected devices in the IoT industry and thanks to the large dimensions of the chamber, the automotive chamber has been widely used by manufacturers or large and/or heavy IoT devices to optimize the connectivity. Examples of DUTs measured in the Automotive Chamber are white goods (refrigerators, washing machines, etc.) or park meters.
