As cellular mobile networks evolve from enhanced GSM to next generation systems by pro- viding faster data connections, personal area networks (PAN) and wireless local area networks (WLAN) are also gaining popularity. Several wireless technologies are emerging, the success of which is unclear due to complex market dynamics, technology development and risks related to both. WLANs have already proved their effectiveness in the indoor business usage by extending the evolution of fixed LANs but the transition from voice to data in mo- bile networks has so far been slow despite the high expectations. Do we see in the outdoor data usage a complementary development of wireless and mobile tech- nologies or does a single radio interface take a dominant role in the future like in the case of GSM? The experiences gained so far indicate that it is very difficult to predict the demand of new technologies and related services. Nevertheless, the launch of a service or R&D project usually requires large investments which imply big risks. The devel- opment of end user behaviour is more incremental than discontinuous. That is why it seems that we need parallel incremental evolution of services during the revolu- tion of radio related technologies. Another important issue is to realize that each emerging radio interface has its own strengths and weaknesses both in economic and technical terms. It is likely that the future network environment is a heterogenic multi-radio network which provides the end user a single subscription with differ- ing service quality depending on the geographic area in question. This publication is a collection of research reports written during the course Re- search Seminar on Telecommunications Business at Helsinki University of Tech- nology. The course is especially designed for students taking Telecommunications Management for their major but is as well suitable for all students that like to de- velop their techno-economic analysing skills in the telecommunications area. The aim of the Telecommunications Management major is to help the students to under- stand the structure and dynamics of economic life and industry with a special focus on the telecommunications by combining business and technology studies. The course provides an opportunity to rehearse scientific writing and presentation skills. The goal of the spring 2003 seminar was to investigate the challenges service providers face when updating their network infrastructure to offer emerging mobile and wireless data services taking into consideration both business and fast develop- ing technology requirements and possibilities. One major challenge is to move from a technology-oriented to a business/service-oriented approach. As a result of hard work we have now a collection of interesting papers of several possible technological scenarios in the mobile and wireless data network evolution. I want to thank all the contributors from excellent papers as well as lively discus- sions during the seminar sessions.
