8.10.2.3 Recommendations for installation
8.10.2.3.1 Standard Topology
The various building infrastructures are grouped into three types of geometric shape.
Coverage areas SQUARE: Coverage areas RECTANGU-
LAR :
Coverage areas ROUND
The distances quoted below give an idea of typical range of a base station. It is clear that a rectangular
zone requires more base stations to provide full coverage.
8.10.2.3.2 Layout technique
For structures with a number of floors, different solutions can be envisaged as a function of:
• the coverage obtained at each level.
• the position of the 4070 IO/EO (higher or lower level).
