This part of IEC 62002 is a radio access specification for mobile, portable and hand-held portable devices capable of receiving DVB-T/H services. It includes informative system aspects as well as specifications for minimum RF-performance. It covers terminals in three main classes, namely integrated car terminals, portable digital TV sets and hand-held portable convergence terminals. Interoperability with integrated cellular radios is also considered. The specification covers the following areas.

  • Frequency ranges

  • Supported modes

  • Definition of receiving conditions

  • Definition of the receiver RF-reference model

  • Definition of degradation criteria

  • Antenna characteristics

  • Channel models

  • C/N-performance with different channels

  • Minimum and maximum input levels

  • Immunity to interfering signals

  • Definition of an ensemble of interference patterns

  • Tolerance to impulse interference

  • SFN-performance

  • Transmitter minimum performance

  • Interoperability of cellular radios

  • EMC aspects
