Abstract: Some factors which could or should affect frequency allocations and assignments in the future are considered. These include propagation predictions, modulation, coding and information processing. In addition a forecast of the use of cables as replacements for Broadcast TV and microwave relay is presented.
Keywords: spectrum efficiency; propagation prediction; frequency assignment; broadcast television; frequency allocation; ground wave
