Imperatives for Optimisation



 RF optimisation remains one of the key challenges in any network.



  Identifying potential faults in the network and resolving them before
  they affect network performance.



  Rectifying causes of faults affecting network performance.




  Leads to efficient use of the spectrum.




                                                                          3
Optimisation Overview




                        4
Need for optimisation

Network issues that may generate a requirement


   Perceived reduction in network quality.

                   Indications from network performance monitoring.

                   Subscriber's experience of using the network.


        Maximising the use of existing infrastructure.

                   Operators wants to ensure the best returns on investment.



    Introduction of new services.

                     Maximise existing resources to accommodate new services such as GPRS.

                     Change in original design parameters.
                                                 ▪ Flawed original design in format.
                                                 ▪ Original design information has changed.

                                                                                              5
