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.).
