[Summary form only given]. As more and more low-cost high-quality devices appear on the market and new applications emerge every day, short-range wireless personal area networks (WPANs), both low and high-data-rate, are on the horizon. Two major efforts of IEEE are underway to enhance the development of WPANs. One is the specification of IEEE 802.15.3a, also known as ultra wideband (UWB), used in...
This paper presents both stationary and mobile signal strength measurements for a wearable UWB radio channel in a hospital environment. The measurements were made using RF-over-fibre technology to eliminate unwanted electromagnetic effects associated with the use of co-axial cables. The results show that received signal strength values depended on whether transmit and receive antennas are in relative...
Knowledge of the error process and related channel parameters in wireless networks is invaluable and highly instrumental in a broad range of applications. Under the IEEE 802.15.4 Low Rate-Wireless Personal Area Networks (LR- WPAN) standard, compliant devices are capable of providing two pieces of information about the channel conditions along with each received packet, the Link Quality Indication...
