3G networks trend
With the increase of traffic, throughput has decreased

3G networks trend
Overload control is essential to maintain network quality
• The network was not dimensioned to support this constant growth of traffic, causing degradation of radio kpi
• Actions to be taken to maintain customers experience:
1. Additional HW capacity in the network• RNC User capacity increase to 80000 (completed)• RNC TP capacity increase to 2 Gbps (completed)• DUW 20 swapped to DUW 30 ( 11 sites)
2. SW features to ensure best capabilities from Network• Payload package improvement ( temporary 2 months licenses planned on 50 sites)• EUL package implemented on 104 sites
3. Deployment of Second carrier (13/24 sites on air)4. Network settings correction for better performance
• max HSDPA / Eul users, code & power settings
5. WCDMA 900 spectrum re-farming (study for 14 sites ongoing)
