Cellular Communication
Coverage Concept
he cellular systems is made up of numerous transmitting and receiving sites, whose
individual coverage areas partially overlap. The concept of frequency re-use, same
frequency is used by several sites, allows a high traffic density in a wide area. Due to the
limited transmission range of the terminals, cellular systems are based on a large
number of base stations on the infrastructure side, scattered over the area to cover, with each
covering a fairly small geographical zone called cell. Cells are often represented by hexagons
(see figure 1.1.).
