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.).
