38 HiPath Cordless IP, Service Manual
3.4.1.2 In Steel/Concrete Buildings
For interiors of brick or light construction materials (Figure 10)
Horizontal direction
A base station must be installed at least every 50 m.
Central installation in the building
The general rules must be observed.
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.
Stairwells,
elevator shafts and
supply shafts
in these buildings usually have strongly-reinforced concrete walls and
stairs. Areas such as these, with poor propagation conditions, often
require additional base stations.
If additional base stations are needed because of a large number of
mobile telephones, see Figure 10.
