Relationships Between Radio Waves and Building Structure and Materials
•
The SIP-CS coverage area is affected more by the building materials and their thickness than the number
of obstacles.
•
Radio waves tend to be reflected or diffracted by conductive objects and rarely penetrate them.
•
Radio waves tend to penetrate insulated objects and are rarely reflected by them.
•
Radio waves penetrate thin objects more than thick objects.
•
The table below shows the transmission tendency of radio waves when they reach objects made from
various materials.

Transmission Tendency
The thicker they are, the less radio waves
penetrate them.
Radio waves can penetrate them, but the more
iron there is, the more radio waves are reflected.
Radio waves usually penetrate them.
Radio waves can penetrate them, but tend to be
reflected.
Radio waves are weakened considerably when
they penetrate windows.
Radio waves can penetrate them, but the more
iron there is, the more radio waves are reflected.
Radio waves are reflected and rarely penetrate
them.
Radio waves usually penetrate them.
