CELL PLANNING CRITERIAS
When migrating
from FLEX™ to ReFLEX™, the height of the antennas has to
be lowered to avoid interference from adjacent cells.
Even though the normal output power of a Mobitex™ base station
is 3W, to get a balanced up- and down link, 6W output power is
required. This is achieved by adding an external amplifier.
EiRP is the actual signal strength, leaving the antennas. The
EiRP values of the base stations in the graph above represent
the signals generated by the base stations, and the EiRP values
of the devices, the signal generated by the pagers.
The calculated cell radius sizes are based on the above values. |
