[show abstract][hide abstract] ABSTRACT: The paper presents a wireless integrated services communications system for indoor and campus use. Whereas most current indoor wireless systems are distinct solutions for different services, our network, WISCS, covers the entire range from low-rate mobiles to high-speed portables. The system employs a picocellular structure in the 60 GHz band to provide capacity demanded by broadband services. The system concept and the employment of simple transponders connected via an optical fibre to a central base station allow a cost effective implementation. Virtual clustering of different number of cells is applied to allow coexistance of low rate mobile users and high rate portable users in one common system. WISCS uses adaptive modulation to yield an optimised performance in both the mobile and portable environment. The project is carried out at Communications Laboratory at Dresden University of Technology. Research includes new optical devices, flexible, efficient and error protected transmitting schemes, mm-wave circuits, antennas, and protocols. A demonstrator is currently under development.
