Abstract : The AirLand Operations warfighting concept requires reliable tactical communications worldwide. Achievement of reliable line-of-sight (LOS) radio communication links worldwide requires a propagation reliability model, including the effects of climate, for use in planning, engineering, and operation. The importance of propagation and climate has been demonstrated by recent experience in Southwest Asia. A CECOM LOS working group has developed a propagation reliability model, including a climate factor, that relates the reliability of an LOS radio link to path length, radio frequency, equipment capability, and geophysical and meteorological variables. Consequently, geophysical and meteorological variables for regions of any country can be included in the planning of tactical LOS communication links thereby helping achieve satisfactory propagation reliability. This report introduces a new application concept, monthly climate factors, since propagation reliability can vary significantly from month to month. In commercial practice, only annual or worst-month climate factors have been utilized. This report concentrates on the methodology by which monthly climate factors are developed which will provide coverage for regions of the world where climate factor information has not been available. Examples are given for Saudi Arabia, Germany and the U.S.. The propagation reliability model has been incorporated into a new battlefield automated radio planning system, the Mobile Subscriber Equipment Network Planning Terminal.
