context: Since the PC1 FWA market does not yet exist, it is unlikely that there are off the shelf components optimized for such a device. This data is being provided for information and is not intended to demonstrate that off the shelf hardware exists for the FWA devices. A filter example is presented below with input power capabilities of 43 dBm which obviously is more than needed for PC1 operation even considering the post PA-losses, but this demonstrates that capable technology is available. Band 12 duplex-filter UMD012A (ctscorp.com) In addition to the above filter with 43 dBm capability, there are also filters with input power capabilities of 38 dBm, which is also more power than is needed for PC1 FWA Nonetheless, the filters are still very large and may not be suitable even for large form factor FWA. Further size reduction will likely be required even for filters for larger FWA devices. Band 12 duplex-filter USD012A (ctscorp.com)
description: The Indoor Anechoic Chamber (IAC) is a specialized testing environment used in telecommunications to measure the performance of base stations and user equipment. It minimizes electromagnetic reflections and provides a controlled setup for accurate measurements.
explanation: The IAC is explicitly described as a testing environment within the context of 3GPP specifications, designed to provide controlled conditions for evaluating telecommunication device performance.
