Popis: | The historical evolution of major wireless access systems in Europe (similarly world- wide) shows that there is a major introduction of wireless access technology in each decade (Fig. 9.1). In the 1990s we have witnessed worldwide introduction of 2G wireless systems dominated by the GSM standard and voice/SMS applications. In the beginning of the new millennium many operators have extended existing 2G system for supporting data applications (e.g. GPRS and EDGE) and next to that 3G wireless access systems were introduced such as UMTS (later enhanced with advanced packet-data features such as HSPA). |
