Ubiquitous homelinks based on IEEE 1394 and ultra wideband solutions

This article investigates a home entertainment and computing network proposal, which takes advantage of ultra wideband (UWB) impulse radio technology and the IEEE 1394 system. We first compare various present home networking technologies. Then we introduce an overview of the IEEE 1394 high-performance serial bus. After that, we describe the network architecture of the proposed home networking scheme, IEEE 1394-based UWB home entertainment and computing networks connected by a wireless 1394 bridge. The IEEE 1394 backbone network and UWB impulse radio subsystem are discussed in detail, as well. Summaries are also provided.     

Ultra-Wideband Signal Impact on the Performances of IEEE 802.11b and Bluetooth Networks

This paper presents the results of a coexistence study investigating the impact of ultra-wideband (UWB) interference on IEEE 802.11b and Bluetooth networks. The results are based on the experimental test measurements made at the University of Oulu, Finland. Simple high-power UWB transmitters are used to interfere with victim networks. Preliminary results show that only under extreme interference conditions with thousands of equivalent Federal Communications Commission– (FCC)-compliant devices in close proximity, will the IEEE 802.11b and Bluetooth networks experience significant performance degradation. The impact of the UWB interference on the IEEE 802.11b network was insignificant if the distance to UWB transmitters was greater than 40 cm. The impact on Bluetooth was even less noticeable. In our study, several high-power UWB transmitters that greatly exceed the FCC radiation regulations have been used, and the measurement settings presents the worst case scenario because of the very short distance between the interferers and the victim system. Effectively our study approximates the use of thousands of FCC-complaint UWB devices in the same space.     

Performance of BICM-OFDM systems in UWB interference

In this paper, we develop an analytical framework for performance analysis of generic bit-interleaved coded modulation orthogonal frequency-division multiplexing (BICMOFDM) systems impaired by ultra-wideband (UWB) interference. For practical relevance we consider multi-band OFDM (MB-OFDM), direct-sequence UWB (DS-UWB), and impulseradio UWB (IR-UWB) interference formats following recent IEEE/ECMA standards or standard proposals. Besides the exact analysis we calculate the bit error rate (BER) for the case when the UWB interference is modeled as additional Gaussian noise. Our results show that in general the BER of the BICM-OFDM system strongly depends on the UWB format and the OFDM sub-carrier spacing. While the Gaussian approximation is very accurate for DS-UWB, it may severely overor underestimate the true BER for MB-OFDM and IR-UWB interference. Our analysis is applicable to e.g. IEEE 802.11 wireless local area networks (WLANs), IEEE 802.16 wireless access systems (WiMAX), and 4th generation mobile communication systems. Furthermore, since the ECMA MB-OFDM standard is also based on the BICM-OFDM concept, our analysis can also be used to evaluate the impact of other UWB signals on ECMA MB-OFDM UWB systems.     

Ultrawideband wireless body-area sensor networks

The operation principles of wireless body-area networks (WBANs) and requirements to their infrastructure are described. The new IEEE 802.15.6 WBAN standard, in which an ultrawideband (UWB) signal is used as an information carrier, is discussed. The general properties of the given standard and its distinctions from the existing wireless personal communications standards are analyzed. It is demonstrated that UWB direct chaotic transceivers are promising for use in the wireless sensor networks based on the new standard.
