Описание: Global mobile satellite communications (GMSC) are specific satellite communication systems for maritime, land and aeronautical applications. It enables connections between moving objects such as ships, vehicles and aircrafts, and telecommunications subscribers through the medium of communications satellites, ground earth stations, PTT or other landline telecommunications providers. Mobile satellite communications and technology have been in use for over two decades. Its initial application is aimed at the maritime market for commercial and distress applications. In recent years, new developments and initiatives have resulted in land and aeronautical applications and the introduction of new satellite constellations in non-geostationary orbits such as Little and Big LEO configurations and hybrid satellite constellations as Ellipso Borealis and Concordia system. This book is important for modern shipping, truck, train and aeronautical societies because GMSC in the present millennium provides more effective business and trade, with emphasis on safety and commercial communications. Global Mobile Satellite Communications is written to make bridges between potential readers and current GMSC trends, mobile system concepts and network architecture using a simple mode of style with understandable technical information, characteristics, graphicons, illustrations and mathematics equations. Global Mobile Satellite Communications represents telecommunications technique and technology, which can be useful for all technical staff on vessels at sea and rivers, on all types of land vehicles, on planes, on off shore constructions and for everyone possessing satellite communications handset phones.
Описание: Making processing information more energy-efficient saves money, reduces energy use, and permits batteries that provide power in mobile devices to run longer or be smaller. The book addresses the need to investigate new approaches to lower energy requirement in computing, communication, and sensing.
Описание: The revolution in wireless communication technology was initiated in the nineties, leading to the development of new mobile communication systems including GSM, GPRS, EDGE, WCDMA, WLAN, HSDPA, WiMAX and recently LTE-Advanced. These technologies have revolutionized the way and manner modern communication is undertaken. The revolution is not only in network design but also in new devices, handsets and Internet enabled devices. It is impossible for these technologies to be created without the support of other fields such as advanced signal processing techniques including OFDM, MIMO, coding, voice, image and video compression. These developments have also created the migration in focus from fixed telephony to IP telephony with complimentary consequences in the use of social networking and online retail and sales. As welcome as the new developments are, the overwhelming depth of technical expertise required to understand and follow the progress in technology advancement makes it harder and harder for the telecommunication engineer to follow without a logical and detailed compendium of the major concepts leading to these advancements.This book is a detailed compendium of these major advancements focusing exclusively on the emerging broadband wireless communication technologies which support broadband wireless data rate transmissions. Several applications of the wireless communication networks including health care, underground communication, biomedical and bio-telemetry systems are detailed in the book. Technical topics:Cellular communication concepts.CDMA, WCDMA, WiMAX, LTE-Advanced and Zigbee.Fading, diffraction and propagation models.Block and error control coding in modern communication networks including msequences, OVSF, Gold and Golay codes.OFDM and MIMO.Multi-carrier and cooperative communication techniques.Applications of wireless communication networks.Optical networks.Electromagnetic interference.
Описание: This book discusses global mobile satellite communications (GMSC) for maritime, land (road and rail), and aeronautical applications.
