With the imminent deployment of ultra wideband (UWB) wireless transmission systems, it becomes fundamental to analyse and predict possible drawbacks of current technologies with the help of propagation measurements. Now that multi-band orthogonal frequency division multiplexing (MB-OFDM) is preferred for cable replacement, wireless universal serial bus (USB) - version 2.0 - in particular, its analysis is of critical interest. This paper presents measurements of the frequency dependent path loss for an indoor residential location, and then shows the performance of MB-OFDM under the worst case scenario conditions. Results show that for a frequency hopped transmission, design alternatives are necessary to maintain the expected data throughput.
