- Important parameters that will determine the solution of the data channel assignment problem are the desired service ceiling and service floor altitudes. The achievable service floor is largely determined by the intersite spacing. If the spacing between any two sites is large, the bottom of the coverage between them will be high. To achieve a low service floor will require close spacing. That, in turn, may require a large number of ground sites to cover a given geographical region.
- A similar analysis for pattern (7) shows that the ratio of service ceiling to service floor would be 13. For example, if the service ceiling were 39 000 feet the service floor would be 3 000 feet. This may appear to be the limit of service floor/ceiling performance given the restriction to no more than 8 DCBs; however, there is a way to extend this range by adopting a tiered approach.
