RAINBOW has been planned as the natural (experimental) continuation of several studies performed in the RACE II framework and concerning the UMTS functional and network architecture. The most qualifying objective of the RAINBOW project is investigating architectural and integration issues through a laboratory implementation of the transport and mobility control functions expected for UMTS. The implementation is based on a conceptual design effort that is part of the project. The radio access part of UMTS is implemented in order to study a "generic" UMTS access infrastructure, able to cope with different innovative radio access techniques (long term view) and, at the same time, to guarantee a soft migration from second to third generation systems (short term view). On the radio side, all the local transport and control functions tied to the terminal mobility (e.g. handover) are implemented on a platform emulating the radio behavior of the adopted radio access techniques. RAINBOW considers both second and third generation radio access mechanisms. Two second generation systems are considered: GSM and DECT. For the third generation radio interface, RAINBOW relies on the outcomes of the CODIT and ATDMA RACE II projects.
