    When it comes to preventive maintenance, electric motors are pretty obliging. The vibration they produce is not just the source of an irritating noise. It is also a handy guide to the health of the motor. And for a new generation of sensors that can detect tell-tale changes in vibration, it acts as a source of energy. Energy harvesting is making it possible to power sensors from their environment.... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (815 KB)

    IP telephony is not just the transport of voice-over IP instead of TDM, but also includes all aspects of a telephony service based on the IP protocol suite, including transport and signalling. In addition, it covers inter-working of the new and old worlds, which includes handsets, PABXes and call centre activity. The term may also be considered to cover integration with the higher level applicatio... View full abstract»

    Many customers may already be experiencing frustration with call quality when they speak to their bank or building society. A recent survey reveals a worryingly low appreciation of the impact of poor voice quality in enterprise IP telephony systems. As consumers and enterprises alike begin to abandon regular fixed-line telephones in favour of VoIP and IP telephony (IPT) products, it is important t... View full abstract»

    In this paper, the latest developments in the new world of mobile TV are discussed. Most mobile TV is an extension of traditional television by other means, offering familiar channels on the same schedule but to a personal and/or portable device. The DVB project is an industry-led consortium of nearly 300 broadcasters, manufacturers and network operators in 35 countries aiming to create interopera... View full abstract»

    The worldwide development of thousands of terrestrial broadcasting networks over the past 90 years depended crucially upon the prediction and measurement of radio field strength. The coverage of these services was quantified by the signal/noise ratio at the receiving end, information needed to specify the transmitting sites, radiated powers, antenna heights, and frequency allocations. The paper di... View full abstract»

    Mobile operators need to adopt an approach that allows them to target specific users with relevant advertisements, and at the same time manage the overall ad-related user experience including user privacy and charging aspects. The mobile device is potentially the most effective advertising media ever developed. It is personal, always-on and enables precise targeting of advertising based on context... View full abstract»

    The paper discusses BGAN (broadband global area network) service from Inmarsat carried by their latest 14 satellites allows data rates of up to about 500kbps per channel in both uplink and downlink. In view of the greater capability and more flexible use, costs can be dramatically reduced, thereby bringing affordable access to many more people. The Thales satellite communications transmitter recei... View full abstract»

    Oliver Heaviside (1850-1925) was a reclusive figure, who did most of his research at home. His recognition as a scientific figure came about from his work on an important scientific text: 'Maxwell's Treatise on Electricity and Magnetism'. Heaviside applied Maxwell's theories to the practical problem of sending an electric signal down a wire, central to the growing telecommunications industry. Over... View full abstract»
