(Transparent standard radio zones )
The design process for DSRC installation is
divided into the following five steps (Steps 1-5).
Step 1
Determine communication areas
Step 2
Radio zone design
Transparent Sheet
Small range (for zone design)
Step 3
Channel layout in the new system
(in the case of multiple zones)
Step 4
Verify interference with
other systems
Step 5
Re-design radio zone
Transparent Sheet
Wide range (for interference verification)
