This deliverable explores the need for a Dynamic Channel Allocation (DCA) mechanism in WAND-like systems. In the context of this study, two main approaches are presented: a centralised and a distributed one. The deliverable describes the basic characteristics of both approaches from which possible advantages and disadvantages are extracted. For each… (More)
A 5.2 GHz gallium arsenide MESFET transmitter monolithic microwave integrated circuit is demonstrated. Gain and 1 dB compression point are as high as 14 dB and +11 dBm respectively.
In the IST (Information Society Technologies) project FITNESS: Fourth-generation Intelligent Transparent Networks Enhanced through Space-time Systems, the issues of re-configurability with Multiple Receive Multiple Transmit (MTMR) antenna systems in various channel, interference, traffic and user requirement conditions and transparent operation across… (More)
A Radio-over-Fibre system to distribute wireless LAN signals over multimode fibre has been designed and analysed. The system employs a novel frequency multiplication technique, to surmount modal-dispersion-induced bandwidth limitation in multimode fibre in general and in Graded Index Polymer Optical Fibre (GIPOF) in particular. This is achieved by frequency… (More)
