Choosing the best site for the CS requires careful planning and testing of essential areas. The best location
may not always be convenient for installation. Read the following information before installing the unit.
Understanding Radio Waves
Characteristics of Radio Waves
The transmission of radio waves and the CS coverage area depend on the structure and materials of the
Office equipment, such as computers and fax machines, can interfere with radio waves. Such equipment
may create noise or interfere with the performance of the PS.
The illustration below shows the special transmitting patterns of radio waves.
Radio waves are reflected by objects made of materials such as metal.
Radio waves are diffracted by objects such as metallic columns.
Radio waves penetrate objects made of materials such as glass.
Relationships Between Radio Waves and Building Structure and Materials
The CS coverage area is affected more by the building materials and their thickness than the number
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
