Radiating Test Requirements Outgrew Existing Rooms
Millimetre wave and large antenna array devices cannot be tested through a cable, so measurement must be made radiating, and the far-field distance needed scales with both frequency and antenna aperture. Growth at 12.6% follows that geometry rather than any commercial argument. Laboratories either build physically larger chambers or install reflector-based compact ranges that fold the distance optically, and a great many discovered their existing rooms had become inadequate without anything changing inside them. A room that was adequate five years ago can be inadequate now without anything inside it changing.
Market Impact: Requires 100 dB attenuation testing
