3.4 Grouping radio areas into cells
Since the cell is the mechanism by which the PBX locates the mobiles, it is necessary to group
the radio areas into cells. The following criteria used to group radio areas into the same cell do
not taken into account whether the area is homogenous or special, but consider only geographic
proximity:
• Maximum number of base stations (and therefore radio areas) in one cell = 8. The
recommended maximum is actually 6 to allow for an additional 2 base stations in case the
initial number of base stations is not sufficient to handle the required traffic (example: if the
number of mobile users increases or if the environment is modified after installation).
