Résumé:
As part of our project graduation MASTER "Planning transmission links ," we started this memory
by recalling the various cellular generations with their access techniques, then it was spread over the
media transmission which is explained the operation of microwave and digital multiplexing hierarchies .
In the last section, we outlined the parameters of the antennas that play a substantial role in the planning,
which we explained the basic steps for creating a 3rd generation network and the results achieved with
the Mentum Elipse software.
