- Studying the feasibility and viability of various future infrastructure architectures and potential road-maps of their deployment is the focus of the 4th Generation Wireless Infrastructures (4GW) project within the strategic Personal Computing and Communication (PCC) program (Molin 1998). In attempting to realize the PCC vision “mobile multimedia to all at today's prices for fixed telephony”, a difficult problem arises. In contrast to the process of solving engineering and business problems in current or imminent wireless systems, where system concepts, requirements and markets are reasonably well known, very little is known about these things over a 10 year horizon. The approach used in the project to tackle this problem, is to use various scenario techniques. Plausible scenarios which describe the telecommunication scene in 2010 and which are used to determine potential technological and other bottlenecks in order to find key areas for research in this field are a very important element in these studies. Some of these scenarios are presented in this paper, together with some implications regarding bottlenecks and key research issues. The results are presented in terms of working assumptions (WAs) used with the project. The WAs are also proposed to provide a framework for interrelating different research activities within PCC.

Key Research Issues in 4th Generation Wireless Infrastructures
- 1998
-
Konferensbidrag (refereegranskat)abstract
- The world of communication is now developing faster than ever. Telecommunication infrastructure deployment in contrast is a slow and costly process demanding along-range strategic perspective in decision making. As aconsequence, R&D efforts are concerned with problems on a time horizon of 10 years or more. Studying the feasibility and viability of various future infrastructure architectures and potential road-maps of their deployment is the focus for the 4th Generation WirelessInfrastructures project within PCC. Determining technological and other bottlenecks to find key areas forr esearch in this area is a very important element in these studies.The methods used for this purpose are various scenario techniques. Plausible scenarios, describing the telecommunication scene in 2010, have been designed based on a number of global trends in technology,economy and politics. The scenario trends have also been verified by using a Delphi survey among leading industrials and scientists in Sweden. Based on these trends, three vivid scenarios are built which implicitly describe the different trends that have been created, for instance, the Big Brother, the Anything Goes, and thePocket Computing. At the end of the paper, the implications of the scenarios to the infrastructure research areas are discussed. In particular, the working assumptions and key research problems in each PCC/4GW work package are revisited and prioritized according to the scenarios. The scenarios are also proposed to provide a framework for inter-relating different research activities within PCC.

Scenarios - A tool for starting a research process
- 1998
-
Ingår i: Proceedings PCC Workshop, Stockholm. ; , s. 6-10

Konferensbidrag (refereegranskat)abstract
- Scenarios can be used as a tool for starting a research process within a group. When putting together a research group of people with different backgrounds, differentcompetencies and different preconceived ideas, special attention has to be put on the problem of integration.Many different "tools" can be used to help merging thedifferent approaches of the individuals constituting thegroup. One such tool is scenario work. Trends arecreated by analyzing and structuring the environment around the project. Combining and extrapolating the trends gives a basis for creating the scenarios. The scenarios are then used to help refining research issues. Both the process and the result are hence of importance. The process aims at revealing the different approachesand possible conflicts due to the different scientific andresearch traditions among the members of the group. Theresult forms a basis for refining and limit the researchquestion. The work within the 4th Generation Wireless Infrastructure project group of the PCC-project aims atfinding important design issues for the infrastructure of a future wireless communication system. Using the scenarios as a starting point the research questions originally put, have been successfully challenged andrefined.

Telecom scenarios for the 4th Generation Wireless Infrastructures

Konferensbidrag (refereegranskat)abstract
- Telecommunication infrastructure deployment, incontrast to the rest of the communication area, is a slowand costly process, demanding a long-range strategic perspective in decision making. Determining key issues for strategic research in this area is thus very important. This paper describes detailed work to that aim, within the PCC project. The aim was to find possible scenariosfor the 4th Generation Wireless Infrastructures (4GW)around year 2010 and to determine their implications onthe direction of research in wireless communications. In this scenario work, a number of trends were created based on the current state of technology, economy and politics. These trends are verified by using Delphi methods. Based on these trends and additional research,three vivid scenarios are built, which picture differentways the trends may develop, The scenarios are called:"Big Brother Scenario", "Anything-Goes Scenario" and"Pocket Computing Scenario". At the end, the paper discusses the implications of the scenarios on thewireless communication research areas. In particular, the working assumptions and key research problems in eachwork package in the 4th Generation Wireless Infrastructure project are verified and prioritized according to the scenarios.
