Planning tasks and network

Pre-planning activities are high especially when operator isGreenfield or deploying a new technology

Main focus in existing operators are in coverage and capacityas well as configuration planning

Optimisation is main task in overall network planning and it isalways recommended to be done and kept as a veryim ortant task of network o eration

1. Make sure that there is enough coverage

Low drop call rate with good quality

2. Put sites close to the users

No blocking if all cells collect some traffic low Interference if UEs are near to the cell

3. Avoid unnecessary overlapping between the cells

Faster, moreeconomic SiteAcquisition &rollout with

Coverage and capacity dimensioning

Dimensioning process has two main parts:

Coverage dimensioning which is handled mainly in Link Budget

Capacity dimensioning

Mainly calculation are for shared DCH + HSPA carrier, but more and morefocusing also on dedicated carriers and multi-carriers

Link budget and Capacity dimensioning are connected to each other inorder to model coverage and capacity iteration and impact on both parts
