Description: Learn about Ultra-wideband (UWB) transmission - the most talked about application in wireless communications. UWB wireless communication is a revolutionary technology for transmitting large amounts of digital data over a wide spectrum of frequency bands with very low power for a short distance. This exciting new text covers the fundamental aspects of UWB wireless communications systems for short-range communications. It also focuses on more advanced information about networks and applications. Chapters include: Radio Propagation and Large Scale Variations, Pulse Propagation and Channel Modelling, MIMO (Multiple Input, Multiple Output) RF Subsystems and Ad Hoc Networks. Platform: |

Description: The main objective of the project was to address the above
mentioned trends and to form a consistent concept of an All-IP telecommunications
network with wireless access. The project took into account both the user’ s and the
network’ s perspectives. In particular, the following areas have been addressed:
• existing implementations and concepts of All-IP wireless networks
• resource allocation and management in wireless systems, both existing and
planned
14
• traffic management and modelling, with special focus paid to the IP-based
services
• modelling for radio wave propagation
• positioning in wireless systems, especially for indoor environment
• network architectures and configurations, including mobile solutions
• dependability studies
• human-technology interaction.-The main objective of the project was to address the above

Description: To improve the performance of short-range wireless communications, channel quality must
be improved by avoiding interference and multi-path fading. Frequency hopping spread
spectrum (FHSS) is a transmission technique where the carrier hops frequency to
frequency. For frequency hopping a mechanism must be designed so that the data can be
transmitted in a clear channel and avoid congested channels. Adaptive frequency hopping is
a system which is used to improve immunity toward frequency interference by avoiding
using congested frequency channels in hopping sequence. Mathematical modelling is used
to simulate and analyze the performance improvement by using frequency hopping spread
spectrum with popular modulation schemes, and also the hopping channel situations are
investigated.-To improve the performance of short-range wireless communications, channel quality must
