name: QZ
full_form: Quiet Zone
context: of the QZ when the source is located at the focus of the mirror. In case of our example, the nominal QZ extends from (x=1.5, y= 0.2) to (x=1.5, y= 0.5). Beam tilt causes the illuminated spot in the plane of the QZ to move off the nominal QZ location. When multiple sources illuminate the mirror, the effective QZ size reduces to the common area across the beams from all sources. Beam tilt consequently has the effect of reducing the effective QZ size. See figure 5.3.2.2.1-4. The reduction in size is a function of both, the angular offset between source and focus, and the distance of the QZ from the mirror.

For power class 1, 3dB beam widths are expected to be between 5 and 10 degrees as an extreme example. A beam tilt in the range of a few degrees could cause a PC1 UE to select a different beam for an off-focus source, relative to a
description: Quiet Zone (QZ) refers to a specific area or region in the context of beamforming and antenna systems in 5G networks. It is related to the quality of the quiet zone (QoQZ) and is affected by factors such as beam tilt, source location, and UE power classes.
explanation: The provided context describes Quiet Zone (QZ) within the technical domain of 5G network beamforming and antenna systems. This falls under a specialized area not directly categorized as network functions, protocols, or services.
