3G Networks and the Handset Capabilities Analysis

3G networks and the handset capabilities analysis

(senegal – tigo)

Ericsson Internal | 2011-02-09 |

3G networks trend

Constant data and voice traffic growth


3G networks trend

With the increase of traffic, throughput has decreased


3G networks trend

With the increase of traffic, we got high blocking


3G networks trend

With the increase of traffic, deterioration of RAB accessibility


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)


Smartphone terminals capability trend

Activating of data inactive Smartphones and shift in data handsets are key for revenue growth
