When Liz Shaw's friend Jean goes missing, the Doctor and U.N.I.T. are drawn to the scene to investigate. Soon Liz discovers a potential alien invasion that will have far-reaching affects on her life, and the Doctor is unexpectedly re-united with an old enemy.

The authoritative, in-depth guide to the new Bluetooth 1.1 specification Bluetooth 1.1's dramatic improvements in interoperability and reliability Includes thoroughly revised coverage of Bluetooth security and power conservation New Bluetooth profiles–including the long-awaited Personal Area Networking profile! The first complete guide to the new Bluetooth 1.1 wireless specification! The Bluetooth specification has been updated to deliver dramatic improvements in both reliability and interoperability. Bluetooth 1.1: Connect Without Cables, Second Edition updates the industry's #1 Bluetooth guide to cover these critical new enhancements–and to offer detailed guidance on every aspect of Bluetooth 1.1 development. Bluetooth SIG committee members Jennifer Bray and Charles Sturman place Bluetooth 1.1 in context, covering markets, applications, complementary technologies, key development issues, and explaining every goal of the new release. They review the components of a Bluetooth system, explain how Bluetooth connections work, introduce essential concepts such as piconets and scatternets, and cover the Bluetooth protocol stack in detail from top to bottom. Interoperability between 1.0b and 1.1 Details of 1.1 improvements with explanations of the reasons behind each change Important changes to Bluetooth low-power modes, encryption, and authentication Bridging Ethernet and Bluetooth with Bluetooth Network Encapsulation Protocol How to use Universal Plug and Play with the Bluetooth protocol stack Profiles which will bring new products including: Human Interface Devices, Hands-Free Phone usage, Basic Printing, Basic Imaging, and Hard Copy Cable Replacement Technologies used by Bluetooth: OBEX, WAP, GSM TS07.10, UPnP, Q.931, and UUIDs Comparison of related technologies: DECT, IrDA, Home RF, HiperLAN, and 802.11 Whether you're experienced with V.1.0 or working with Bluetooth for the first time, Bluetooth 1.1: Connect Without Cables, Second Edition is your definitive resource for building interoperable, reliable wireless applications–right now!

This roadmap for implementation and application construction is aimed at the Bluetooth community that is currently developing applications on top of the Bluetooth Core. Gratton details the usage scenarios for Bluetooth, known as Profiles, essentially defining the end-user applications and their interoperability requirements.

With Bluetooth Low Energy (BLE), smart devices are about to become even smarter. This practical guide demonstrates how this exciting wireless technology helps developers build mobile apps that share data with external hardware, and how hardware engineers can gain easy and reliable access to mobile operating systems. This book provides a solid, high-level overview of how devices use BLE to communicate with each other. You’ll learn useful low-cost tools for developing and testing BLE-enabled mobile apps and embedded firmware and get examples using various development platforms—including iOS and Android for app developers and embedded platforms for product designers and hardware engineers. Understand how data is organized and transferred by BLE devices Explore BLE’s concepts, key limitations, and network topology Dig into the protocol stack to grasp how and why BLE operates Learn how BLE devices discover each other and establish secure connections Set up the tools and infrastructure for BLE application development Get examples for connecting BLE to iPhones, iPads, Android devices, and sensors Develop code for a simple device that transmits heart rate data to a mobile device

Until now, developers and researchers interested in the design, operation, and performance of Bluetooth networks have lacked guidance about potential answers and the relative advantages and disadvantages of performance solutions. Performance Modeling and Analysis of Bluetooth Networks: Polling, Scheduling, and Traffic Control summarizes t

Bluetooth technology has enjoyed tremendous success, and it's now employed in billions of devices for short-range wireless data and real-time audio or video transfer. In this book the authors provide an overview of Bluetooth security. They examine network vulnerabilities and provide a literature-review comparative analysis of recent security attacks. They analyze and explain related countermeasures, including one based on secure simple pairing, and they also propose a novel attack that works against all existing Bluetooth versions. They conclude with a discussion on future research directions. The book is appropriate for practitioners and researchers in information security, in particular those engaged in the design of networked and mobile devices.
