GSM/GPRS Radio Network Optimisation

ELP 0202  ★★★★

The GSM/GPRS Radio Network Optimisation starts from describing the Quality of Service concept and optimisation process. Next the course discusses in details algorithms with their parameters which control various aspects of the Mobile Station (MS) in the radio network and which change impacts the Quality of Service.

The training also presents tools which are used in radio network optimisation. From the tools on the MS side the course included TEMS Investigation log-files analysis and report generation. From the tools on the network side the radio network statistics of accessibility, retainability and service integrity are analysed.

Target audience – Who should attend and benefit

It is recommended for those who are involved in tuning activities of the GSM/GPRS network.

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

Participation in the GSM Cell Planning Flow (ELP 0104) course is recommended or equivalent knowledge of the cell planning process is required.
