Chapter two, Technologies and applications, provides an overview of the key technologies for the mobile internet, and their position vis-a-vis alternative network technologies such as Wireless LANs, and Bluetooth. The chapter also looks at security issues and how the mobile internet is impacting the workplace.

Chapter three, Demand, market structure and economic implications, looks at the commercial challenges involved in creating a mass market for mobile Internet services. What are the prospects for market development, and what lessons can be learned from the early experiences with 2.5G and 3G systems?

Chapter four, Regulatory and policy aspects, looks at the challenges to policy-makers and regulators in creating the right environment for the market to develop. This includes processes of licensing but also dealing with issues that arise in the post-licensing environment, for instance related to competition policy, interconnection and network sharing.

Chapter five, Case studies, reviews how policy-makers and regulators in a range of countries have responded to the challenges. This chapter draws on case studies on the licensing of 3G mobile systems in a range of countries at different levels of socio-economic development, and draws a number of lessons from the diverse experiences these cases present.

Chapter six, Conclusions: Towards a mobile information society, looks ahead to the broader challenges to society that are posed by the mobile Internet. In so doing, the chapter considers some of the issues that will be debated at the World Summit on the Information Society (WSIS) to be held in two phases, in Geneva, 10-12 December, 2003 and in Tunis in 2005.
