Operator Challenge

The operator had invested notablyto network quality & capacity, andexpected to obtain the #1 position in the national network benchmark.  However an objective benchmark campaignproved the operator’s average DL speed was actually 3Mbps behind the best network. This result was unexpected, as the operator hadthe mostdensesite-grid with the highest LTE-A capacity, and almost all performance KPIslooked favorable to the Operator

Omnitele Assignment

Quantify the reasons why there isgap to the other operator and provide an action plan for optimisation& expansions that will secure the winner position in the next benchmarkcampaign

Solution

Predictive analytics for drive-test measurement data, to quantify the true reasons behind the benchmark gaps and to provide concrete action plan to close the gap.

Input data to the analysis: Raw drive-test logs

Analysis

Step 1: Quantify cell-level root-causes' net impact on the operator gaps  

Operator 1 gets almost 4Mbps advantage from the lower LTE interference, and also smaller gains from better coverage, spectrum, MIMO. However, the disadvantage with lower modulation scheme alone turns the net difference into negative.

Step 2: Quantify cell level improvement potential from different actions

Achievable KPI improvement, and the resulting impact on the benchmark, is quantified for each sector. The action can include:

• Coverage or dominance optimisation
• Parameter optimisation
• Spectrum expansions and new features

Step 3: Create the most feasible action plan to close the benchmark-gap

• Network wide parameter-optimisation
• Radio optimisation in 7% of cells
• Capacity expansions in 5% of sectors
