Abstract
  • Although recent advances in wireless system technologies have provided ever increasing throughputs, end user demand continues to increase unabated. The research investigates the performance of a system harnessing two relatively new but powerful technologies, Multiple-Input and Multiple-Output (MIMO) and Ultra Wideband (UWB) transmission as a possible solution to meet the growing demand for capacity. Each of these technologies in its own right has been subject to a large volume of research and has been proven to bring an increase in throughput. Nevertheless the predicted future demand will outstrip what each strategy can provide individually. MIMO-UWB systems are thus an emerging wireless solution with, in particular, the potential to satisfy short distance, high speed transmission requirements within indoor environments. Before any system is deployed it is important to characterise performance within representative operating environments. The study therefore emulates appropriate indoor environments, defines an experimental protocol to execute a range of measurements that provide robust evidence of the behaviour of the combined system within indoor scenarios. The application scenario dictates that the transmitter represents a gateway device attached to the ceiling and the receiver, a user device set on a table. The sequence of measurements relate to different positioning of the user device, with different angles and ranges to the gateway device, the layout of antenna placements being important. The output of the study is an accurate model for engineers and, the foundation for the design of MIMO-UWB systems for indoor services.
