GSM, UMTS, HSPA and LTE Overview

Course description

Mobile networks of today are true multimedia networks, providing telephony, data and video services to mobile end-users. Historically, mobile networks have been optimized for mobile telephony services. The data related traffic has surpassed the telephony generated traffic.In addition, the end-user expectations on the mobile data services, in terms of high quality, lead to tougher requirements on network performance, such as bandwidth availability, packet loss and delay.Some mobile operators are facing the challenges of managing several different generations of mobile technologies simultaneously; 2G, 3G and 4G. The course “GSM, UMTS, HSPA and LTE” covers all these network technologies but with the emphasis on LTE.

Target audience

The target audience is engineers, project leaders, marketing staff or others, who need an efficient and thorough introduction to the mobile telecom technologies.
