Environmental Changes ◦ New Buildings, New Highways, Trees etc Ageing ◦ Reduction in Power, Cable loss Interference Issues and Unpredicted Noise Floor. ◦ Over-shooting, Reflection ,Inter-technology Carriers.
- 18. Increasing Network Quality. Deals with Speech and Data Quality (i.e.. RXQual, BLER ) to increase customer satisfaction. Increasing Network Availability. Deals with call performances, i.e. DCR, HFR. Increasing Network Capacity. Deals with capacity management efficiently. INCREASED REVENUE !
