z X–ray rooms in hospitals protected by lead walls, computer rooms in banking buildings
protected against unwanted interference, etc. do not allow radio signals to enter.
z Exhibition halls or production halls may give reflections due to huge metal structures. This
causes interference which reduces the capacity and coverage area per Base Station.
3.4 Departmental Differences
z More traffic is generated in sales, purchasing, technical support departments, cafeterias, etc.
than finance & administration or research & development. Consequently, a higher traffic
capacity is needed in these areas requiring additional Base Stations to be installed. More
details follow in Chapter 5.
3.5 Architecture
z Central areas giving access to stairs and elevators may require extra Base Stations due to
heavier constructions.
z Coverage in elevators may require Base Stations closer to or in the elevator shaft.
z Corners and irregularities in the construction (partial renovation, extensions of older buildings
etc.) have an influence.
z Concentration of air–conditioning ducts, etc. may influence the coverage.
