Frequently asked questions
A rack-mountable over-the-air (OTA) chamber offers a compact, integrated solution for testing wireless devices without the space and cost requirements of a traditional lab benchtop system. Because it is designed to fit into a standard equipment rack, it can be installed directly alongside network emulator, common interface unit, remote radio heads, and other instruments in a lab bench or rack environment. This saves floor space and enables streamlined workflows where multiple systems can be used in parallel.
These chambers are particularly valuable for protocol and functional testing of small wireless devices, such as smartphones, IoT sensors, wearables, and modules. They provide the required shielding and absorber-lined interior in a much more manageable form factor. By keeping the test environment close to the instruments, rack-mountable OTA chambers reduce cable lengths, minimize loss, and simplify integration into automated test setups. Compared to larger chambers, they also tend to have faster setup times and lower operational overhead, making them well-suited for R&D verification and Repair labs.
Shielding is critical in any OTA chamber, whether it is full-size or rack-mountable. The goal is to ensure that external signals, such as cellular, Wi-Fi, or Bluetooth traffic in the building, do not leak into the chamber and interfere with the measurements. At the same time, shielding prevents test signals generated inside the chamber from radiating outward and causing unintended interference with other equipment.
The level of shielding required depends on the frequency range and sensitivity of the device under test, but in general, shielding effectiveness of 70 decibels or more is desirable for wireless device testing. Rack-mountable chambers are designed with high-performance shielding materials, absorbers, and RF-tight door seals to achieve this level of isolation. When properly specified and installed, they can deliver good shielding performance, ensuring that measurements reflect only the controlled test conditions.
