WCDMA Radio Network Planning

ELP 0161  ★★★★

WCDMA Radio Network Planning introduces the principles of the WCDMA air interface. First, the course presents spread spectrum technology, physical layer of the radio interface and network planning aspects. Next special attention is put on the description of WCDMA radio network planning process including coverage and capacity planning, interference analysis and network optimisation. Also the effect of the propagation environment, base station solutions and GSM co-planning are discussed as well as the new UMTS service architecture and Quality of Service (QoS).

Target audience – Who should attend and benefit

It is recommended for those who are involved in the cell planning and optimisation process.

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

Ability to understand technical subjects is required. General knowledge in GSM and UMTS is recommended before attending the course. Participation in the GSM Cell Planning Flow (ELP 0104) or equivalent knowledge is beneficial.
