This paper presents some of the results of the Fourth Generation Wireless project (4GW) of the Personal Computing and Communications program (PCC), the major Swedish academic research effort on future communications systems, launched in late 1997.In the 4GW project, scenarios have been used as a tool for formulating relevant research topics related to future wireless systems.
By working with scenarios the project group has been able to challenge some of the assumptions commonly made in the field of wireless. Since the project group is multidisciplinary, the work has also helped the members of the project group to understand the differences between the research traditions they belong to.
The scenarios, as well as the ensuing research into various wireless related topics, point to a vision of fourth generation systems where ?low-hierarchy?, user-deployed infrastructures are the prime candidate. Fourth generation systems will offer short-to-moderate range communications with very high data rates (>100 Mbit/s). They will employ array signal processing, and ad-hoc operation to provide the required coverage. A key aspect of their design will be the fact that they will be deployed in environments where large scale wireless, and wired, infrastructures are already in operation.
