Installation Preparation
1.
Prepare a drawing of the building where you want to install the Cell Station (CS).
(A drawing which shows the size or main structural material of the wall, partition wall or
ceiling is preferable.)
2.
Consider the service area required for the users.
3.
Examine the service area on the drawing.
a)
Make a circle around the installable area by determining the radio transmission range
(inside: 25 m – 50 m, outside: 70 m – 100 m). Note that a CS cannot be installed outside
a building.
b)
If more than one CS is required, the radio transmission ranges should overlap. The
overlapping range should be at least 5 to 10 meters.

Material
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 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.
Radio waves can penetrate them, but the more iron there is, the
more radio waves tend to be reflected or diffracted.
