Free-Space Optics
Free space optics is a telecommunications technique which is already being used for everyday exchange of information and has many advantages over other techniques (bandwidth, low cost, mobility of the equipment, security, etc.); within the next decade, it is likely to become an integral and essential part of data-processing architectures and telecommunications. A history of wireless optical telecommunications is given, together with a recapitulation of the application of the principles of electromagnetism to free-space optics. Coverage is also given to the transmitters and receivers of optical beams, whih are the basis of any optical communication system. These devices were responsible for the first truly significant advances in the performance of these systems. Special attention is given to the problems associated with the propagation of photons, both in the presence and absence of obstacles, since these are key issues in gaining an understanding of future telecommunication systems based on wireless optics. Finally, the authors considwer standards, as well as safety and confidentiality issues.
GPRS in Practice
Professionals quickly discover that, although the technical specifications for GPRS cover all parts of the engineering functions in detail and depth, they are lacking in one important feature; the conceptual framework within which the specifications sit – GPRS in Practice fills this gap. By beginning with an explanation of why GPRS is necessary and describing the core concept of GPRS operations, the TBF (Temporary Block Flow), a revision section then covers the GSM Air Interface with its Radio, Physical and Logical channels and this progressively leads to the GPRS logical channels – what they do and how they do it. The book then moves on to a brief introduction of the GPRS protocol stack which provides a launch pad for a detailed trip into all the layers of this stack, with detailed diagrams and explanations of each layer integrated into an overall understanding of how the GPRS service operates in practice. Provides descriptions of why procedures are specified and then clearly explains how the specifications work in practice Provides a layered view of the GPRS protocol and deals in detail with each layer separately Includes numerous acronyms and abbreviations accompanied by their full meaning An invaluable resource for Mobile network operators, Development and deployment engineers and Handset designers.
Location-Based Services
Location-based Services (LBSs) are mobile services for providing information that has been created, compiled, selected or filtered under consideration of the users’ current locations or those of other persons or mobile devices. Typical examples are restaurant finders, buddy trackers, navigation services or applications in the areas of mobile marketing and mobile gaming. The attractiveness of LBSs is due to the fact that users are not required to enter location information manually but are automatically pinpointed and tracked. This book explains the fundamentals and operation of LBSs and gives a thorough introduction to the key technologies and organizational procedures, offering comprehensive coverage of positioning methods, location protocols and service platforms, alongside an overview of interfaces, languages, APIs and middleware with examples demonstrating their usage. Explanation and comparison of all protocols and architectures for location services In-depth coverage of satellite, cellular and local positioning All embracing introduction to 3GPP positioning methods, such as Cell-Id, E-OTD, U-TdoA, OTDoA-IPDL and Assisted GPS Explains the operation of enhanced emergency services such as E-911 Identifies unsolved research issues and challenges in the area of LBSs This comprehensive guide will be invaluable to undergraduate and postgraduate students and lecturers in the area of telecommunications. It will also be a useful resource to developers and researchers seeking to expand their knowledge in this field.
Multiple User Interfaces
Multiple User Interfaces allow people using mobile phones, lap tops, desk tops, palm tops or PDAs to access and read information from their central server or the internet in a coherent and consistent way and to communicate effectively with other users who may be using different devices. MUIs provide multiple views of the information according to the device used and co-ordinate communication between the users. Multiple User Interfaces: Engineering and Applications Frameworks is the first work to describe user interface design for mobile and hand-held devices such as mobile phones. Given the proliferation of books on web site design in the late '90s, this promises to be the forerunner in a new wave of books dealing with the issues specific to small screens, limited memory and wireless transmission. It also deals with problems relating to multi-user functionality and sharing the same application over various platforms. Offers a comprehensive account of state-of-the-art research Combines human and technical aspects including social interaction, workflow, HCI, & system architectures. Provides practical toolkits, guidelines and experience reports Includes contributions from leading experts at all the key institutions – Virginia Tech, Concordia University, Lancaster University, Ericsson & Intel With such a unique and cutting-edge approach researchers and developers working on user interface design in companies manufacturing handsets and other portable devices, university HCI groups and companies providing web-based information services for delivery to hand-held devices will find this indispensable.
Phishing and Countermeasures
Phishing and Counter-Measures discusses how and why phishing is a threat, and presents effective countermeasures. Showing you how phishing attacks have been mounting over the years, how to detect and prevent current as well as future attacks, this text focuses on corporations who supply the resources used by attackers. The authors subsequently deliberate on what action the government can take to respond to this situation and compare adequate versus inadequate countermeasures.
