2G/GSM to 4G/LTE Evolution

Ewolucja sieci od 2G/GSM, przez 3G (WCDMA, HSxPA) do 4G/LTE

This training event presents the evolutional path of mobile systems starting with 2G systems (GSM/GPRS/EDGE) th rough 3G systems (WCDMA, HSxPA) to LTE and 4G standards following 3GPP documentation and real world implementations. Among different aspects of a mobile systems major pressure is put on network architecture including radio access and core network. Additionally, the course also covers evolution of services.

Target Audience

Anyone willing to understand the differe nces between 2G,3G and 4G systems and the way they can coexist in telecoms environment providing high speed mobile access to diversified services.


Ability to understand technical subjects. Prior knowledge of mobile systems would a be an advantage when attending the course.
