Since the early 1970s, there has been an increasing number of cases of damage to communication structures from vandalism [6]. Communication structures are vulnerable to
vandalism due to their own nature, that is, many are located in remote locations making
access for protection difficult. Though communication structures can be a target for
those who fully disagree with the service they are providing, the scale of such vandalism
varies from carelessness to full terrorism. Carelessness should not strictly be considered
as vandalism, but more correctly covers any type of accidents that should be prevented,
