Link Budget Analysis and Throughput Measurement for Multi-Antennas WiMedia UWB Systems

This paper examines a WiMedia UWB product by performing comprehensive throughput measurements and a path loss and link budget analysis based on the measured data in office and residential environments. The UWB product conforms to WiMedia's multi-band orthogonal frequency division multiplexing specification. The link budget analysis results together with detailed throughput versus range measurements demonstrate the impressive performance of the WiMedia UWB module for high speed data transfer under very low power constraint, e.g., 0 dB fade margin and capable of supporting up to 324 Mb/s in iPERF.
