Hypothetical Range of Radio Zone
When designing the image of a radio zone provided by a ZT, the radio zone can be drawn by using a specific
prefixed distance characteristics value. Provided that a ZT is installed on a wall, the hypothetical distance
characteristics range of the radio zone are as follows:
Indoor (general):
Indoor (floor and corridor with unobstructed view):Radius of 65 feet (20 meters) approximately
Outdoor:
imately
The range shown represents model values. Adjustment of the radio zone should be needed to design the
final drawings as the radio wave fluctuates unpredictably. It is fundamental that each radio zone be assigned
to ensure sufficient overlap as shown below.
Radius of 49 feet (15 meters) approximately
Radius of 164 to 196 feet (50 to 60 meters) approx-
