• For interiors with concrete and steel dividing walls (Figure 13)
– Central installation in the building
The general rules must be observed.
– Horizontal direction
Because of the relatively high attenuation of concrete and steel dividing
walls, a base station must be installed in these buildings at least every 25
m.
– Vertical coverage
Care must be taken to ensure that not more than one reinforced concrete
ceiling is in the direct propagation route between the base station and the
area where the mobile telephones are used. Adequate coverage cannot
otherwise be guaranteed. For
– stairwells,
– elevator shafts and
– supply shafts
additional base stations are also often necessary.
In the case of elevators, a base station can be installed in the elevator
cabin itself.
– If additional base stations are needed because of a large number of
mobile telephones, see Figure 13.
