TAILIEUCHUNG - GSM and UMTS (P23)

GSM’s Success Factors Friedhelm Hillebrand 1 Acceptance in Europe, the First Step The first big step was the success and acceptance in all European countries. GSM was certainly the right product at the right time. There were countries like France and Germany who needed capacity in the early 1990s. Other countries like the UK, Italy, the Nordic countries had high capacity analogue systems. They were attracted by superior GSM features like small hand-held terminals as well as superior services like international roaming, SMS and data services. Also the high security, capacity and quality played an important role | GSM and UMTS The Creation of Global Mobile Communication Edited by Friedhelm Hillebrand Copyright 2001 John Wiley Sons Ltd ISBNs 0-470-84322-5 Hardback 0-470-845546 Electronic Chapter 23 GSM s Success Factors Friedhelm Hillebrand1 Acceptance in Europe the First Step The first big step was the success and acceptance in all European countries.

Other countries like the UK Italy the Nordic countries had high capacity analogue systems. They were attracted by superior GSM features like small hand-held terminals as well as superior services like international roaming SMS and data services. Also the high security capacity and quality played an important role. In addition the newly licensed operators put forward demanding requirements. These demanding market requirements led to an advanced future proof system design and specification and evolution. The way all players in Europe worked together towards a common goal and the energy this created was essential. In this process a capability was developed to reach decisions even on the most controversial questions which had not been anticipated. A key activity to build momentum was the co-ordinated infrastructure procurement by the operators in 1988 which lead to ten contracts which convinced manufacturers to take GSM Globalisation by World-wide Opening For the globalisation again the principle the right product at the right time was the key. In the early 1990s GSM existed in many networks. Advanced terminals and infrastructure were available. International roaming was in operation. This worked together due to the comprehensive GSM system standard. There was no real competition in digital systems by other standards. Therefore the advantages over existing analogue systems became the key for the countries outside Europe. And GSM was future-proof. The globalisation of GSM .
