WCDMA Radio Network Optimisation

ELP 0607  ★★★★   Public schedule

The success of optimisation process depends a lot on the understanding of the coverage and capacity requirements, the use of different functionalities as well as a clear understanding of KPIs to evaluate network performance. The course discusses important WCDMA functionalities with emphasis on relevant parameters. The course also discusses counters and KPIs used in the network performance analysis. To support general troubleshooting, the course also presents important parameter setting and typical optimisation cases.

Target audience – Who should attend and benefit

The course is addressed to network engineers involved in optimisation process.

Prerequisites – What you are supposed to know prior to the course

Participants are recommended to have prior knowledge on existing 2G and 3G systems. The course does not discuss WCDMA network basics.
