Imperatives for Optimisation
3
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.
Optimisation Overview
4
Need for optimisation
Perceived reduction in network quality.
Maximising the use of existing infrastructure.
Introduction of new services.
Indications from network performance monitoring.
Subscriber's experience of using the network.
Operators wants to ensure the best returns on investment.
Maximise existing resources to accommodate new services such as GPRS.
Flawed original design in format.
Original design information has changed.
Change in original design parameters.
Network issues that may generate a requirement
