In this chapter we discuss the problem of calculating line-of-sight (LOS) between objects located at different points of a given digital-elevation-model. This problem finds practical application in many areas of civil engineering, military tactical command and control, cellular operators, wind-turbine positioning and even ray-tracing.

THE DILEMMA TURNS US AROUND and distorts our priorities. As a result, we end up pursuing goals and outcomes that are not necessarily important, valuable, or consistent with what we care about. Accelerating this “creep and drift” is one of the dilemma’s specialties.

Terrestrial line-of-sight links
2012This chapter describes propagation issues relating to outdoor terrestrial line-of-sight (LOS) links, which are a widely used example of, in ITU terminology, a 'fixed service'. The significance of 'fixed' in this context is that both ends of the radio path terminate in equipment used under controlled conditions, unlike broadcasting or mobile services ...
