ITU-R BS.2214-3 3 1 Introduction This Report provides planning parameters for the following digital terrestrial broadcasting systems: system C (also known as HD Radio), system G (also known as DRM+), system A (also known as DAB) and RAVIS system in VHF Bands. DRM+ is designed for use in VHF Bands I, II and III. RAVIS is designed for use in VHF Bands I and II. DAB is designed for use in VHF Band III. HD Radio system is designed for use in VHF Band II. The Report defines a framework for calculating all relevant network planning parameters that are very similar for the systems. The system characteristics of digital System A, System C and System G are included in Recommendation ITU-R BS.1114 and the description of RAVIS is contained in Report ITU-R BT.2049. Framework for evaluation of planning parameters is given in §§ 2 to 3. Section 4 gives planning parameter for DRM+. Section 5 gives planning parameter for RAVIS. Section 6 gives planning parameters for HD Radio. Section 7 gives planning parameters for DAB. Normative and technical references are given in Annexes 1 and 2 respectively. To calculate the relevant planning parameters minimum median field strength and protection ratios, firstly receiver and transmitter characteristics, system parameters as well as transmission aspects as common basis for concrete digital broadcasting transmission network planning are determined. All parameters are either derived or the reference to the source of origin is given. Various typical reception scenarios are taken into account to match as much as possible planning and prediction scenarios. 2 Reception modes A total of seven reception modes can be distinguished and include fixed, portable and mobile, where portable and mobile receptions are further sub-divided. Reception availability as addressed by ITU in [15] and [18] considers certain percentile ranges over time and locations but does not attempt to address the
