With 3G mobile technologies already rolled out by over 200 operators in over 80 countries, standards bodies, manufacturers and operators are looking towards the next generation of mobile technology. The UMTS standards body, 3GPP has created a plan to achieve ambitious goals for where mobile communications should go. This is Long Term Evolution LTE.
For technicians and technical professionals to stay in touch with this evolution, a good grounding in the technology and terminology of 2G, 3G and 4G systems is needed. The key conceptual design philosophies of each generation need to be understood in order to build effective networks as they evolve. Transition will not occur overnight. Indeed it may be many years before every network has transitioned every part to 4G. The mechanisms of linking the different technologies must be appreciated.
The increased performance in the future will depend upon changes in the radio path. The new or changed areas include the use of MIMO antenna systems, OFDM-based multiple access as well as the architectural changes.
This course describes the technical features of 2G GSM, 3G UMTS and the evolution of technologies that will change to support 4G LTE. This includes, notably, the core network which has its own evolution plan, SAE, System Architecture Evolution. Examples of switched configuration will be studied to illustrate practical aspects.
