This document addresses the signal conditions that may be encountered with assessment of the potential impact upon the front-end portion of a receiver of A/153-based mobile digital television broadcasts. This document provides recommended performance guidelines that are intended to maximize reception. In general, the recommendations in this document build on those contained in A/74 (which applies to fixed terrestrial receivers), with the addition of new guidelines pertinent to mobile reception. Areas where the recommendations are new or different include: dynamic multipath, antenna configurations in mobile receivers, the effects of more limited power supplies, possible proximity to interfering signals, and presence of unlicensed devices radiating in the TV bands.
