Download or read book TErrestrial Trunked RAdio TETRA written by Peter Stavroulakis and published by Springer Science & Business Media. This book was released on 2007-05-20 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial Trunked Radio (TETRA) has become the tool to design any type of public security systems, in particular due to the strongly increased security demands for mobile systems. In this book, the authors show how TETRA can be strongly improved and these improvements will most probably be part of future TETRA standards. The areas examined include channel assignment and multiple access techniques, video transmission, wireless LAN integration, and the establishment of multiple wireless mesh networks. Since the requirements for these networks is security, the authors show that innovative techniques such as those based on chaotic signals can be used in order to maximize security. The book is a vital reference point for researchers with ambition to find the general solution for modern problems of public safety.

Available in PDF, EPUB and Kindle. Book excerpt: 1.1 COMMUNICATION WHILE TRAVELLING The pace of our daily life has been increasing for several decades. Our needs have multiplied as new products have appeared and then been replaced after a few years, or even months, of existence by a more fashionable product or one of higher performance. The life cycles of the technologies used in consumer and professional electronic products are also becoming shorter. This acceleration is an inherent fact of our consumer society. and the relationship between people and machines are Lifestyles due to the multiplicity of ephemeral consumer products. Objects changing no longer have a history; they are merely tools which fulfil a predetermined function. Personal portable products are of a new type which has appeared among pens, wallets, these impersonal objects. This category includes watches, handbags, calculators, portable radios and pocket telephones. As these products for the pocket are carried on one's person, they belong in a very personal way and have, therefore, a speciftc identity corresponding to the image which they are given. In the evolution of lifestyles, the explosive increase of travel and time management are major factors. The pocket telephone is, therefore, remark able for two reasons. It is not only an impersonal tool or product but is also very much a personal portable product. The possibility of distant com munication while travelling, being able to call or be called at will anywhere at any time permits the pocket telephone to be often considered as a desirable, almost magic, personal item.
Download or read book Handbook of Telemedicine written by Olga Ferrer-Roca and published by IOS Press. This book was released on 1998 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to one of the numerous definitions of telemedicine "providing medicine at a distance" any doctor being trained in the use of some telematic devices could effort that practice. The reality is far from this because, to assure a safe practice, people have to learn and bear a minimum understanding of a wide range of topics: from economics to telecommunications and from medicine to legal aspects Technology learning is not limited to technology itself but linked to its social practical consequences in all their aspects. To guarantee that none of the aspects related with telemedicine are missed, this minimum knowledge has to be fixed, organised and in some way standardised. The main purpose of this book is to structure the basic knowledge linked to teaching to provide or practising telemedicine as well as an overview of the technology developments linked to this new discipline. As expressed in the title, the book is precisely structured as a "handbook" ( the only existing one ) whose main value is the joint opinion of all the participating authors of what are the minimum teaching requirements for anyone that would like to learn telemedicine. It is not a full treatise nor a complete recollection of all telemedicine applications or telemedicine basics. It was built with the aim of creating awareness to the academic authorities and health care community representatives on the fact that telemedicine practices in any of their aspects (technology development, telecommunications approach, law and regulations, medical practice), require a minimum knowledge that has to be respected in order to guarantee safe and appropriate medical practice. Nowadays this fact is enhanced by the evidence that welfare expenses cannot be endlessly increased, whilst an efficient health provision system in the context of the information society, will mark a new trend to configure health care practice in the next century. If training and teaching schemes are to cope with the demands of society it seems obvious that those careers and professions that are purvey to the Body of Knowledge BoK of telemedicine should consider structured and sufficient training in telemedicine.
