WG3 dealt with both propagation (at microwave and mm-waves) and system
aspects. The group concentrated on high data rate (>10 Mbit/s) short range
communication in the indoor environment, both from a theoretical (modelling and
simulation) and experimental standpoint, using millimetre wave radio frequencies
(>30 GHz) where there is adequate bandwidth available. Attention has also been
paid to outdoor environments and infrared wavelengths, with particular reference to
High Performance Radio Local Area Networks (HIPERLAN), considering typical
classes of application. Attention was also given to the safety aspects for both
millimetre wave and infrared radiation and to study the performance of possible
system configurations for wireless optical systems (and relevant constraints).
