1.3 BASIC KNOWLEDGE ON ZT INSTALLATION
1. 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) : Radius of 49 ft (15 m) approximately
Indoor (floor and corridor with unobstructed view): Radius of 65 ft (20 m) approximately
Outdoor: Radius of 164 to 196 ft (50 to 60 m) approximately
The range shown represent 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.

INSTALLATION DESIGN
2. Image of ZT installation
Assuming a ZT is installed in a general office environment, one ZT can rarely cover the entire service area.
So, a general service area is composed of multiple ZTs. The diagrams below show the image of ZT
installation.
a. Single Floor Installation
ZTs are ideally installed at right angles or zigzag like spots on a dice.
b. Vertical Successive Floor Installation
It would be ideal to install ZTs at zigzag position alternately by even-number and odd-number floors so
that transparent radio waves penetrating floors or ceilings are sufficient enough to receive electric field
to be a radio zone and transparent radio wave between floors is sensed.
