Q: What is a clutter?
� Clutter refers to a Land Use/Land Cover classification of surface features which impact on radio wave propagation. These features are classed according to their physical and electrical properties.

Q: What is a cluster?(in GSM)
� The number of cells per cluster is restricted by the requirement that the clusters must fit together like jig-saw pieces. The possible cell clusters are the 4-,7-,12- and 21-cell clusters.

Q: What are heights in MAP?
� clutter altitude: aka Digital Terrain Model (DTM) is a continuous model of ground-level land surface, represented by a digital raster grid with each grid cell holding an elevation value. A DTM is a fundamental data input for radio propagation studies in that terrain blocks and reflects radio waves.
� clutter height: the average building height on clutter.
� 3D building: the shape and height of real buildings
