Build awesome and complex robots with the power of Arduino
WHO THIS BOOK IS FOR This book is for anyone who has been curious about using Arduino to create robotic projects that were previously the domain of research labs of major universities or defense departments. Some programming background is useful, but if you know how to use a PC, you can, with the aid more » of the step-by-step instructions in this book, construct complex robotic projects that can roll, walk, swim, or fly. ABOUT THIS BOOK * Develop a series of exciting robots that can sail, go under water, and fly * Simple, easy-to-understand instructions to program Arduino * Effectively control the movements of all types of motors using Arduino * Use sensors, GSP, and a magnetic compass to give your robot direction and make it lifelike IN DETAIL Arduino is an open source microcontroller, built on a single circuit board that is capable of receiving sensory input from the environment and controlling interactive physical objects. Arduino Robotic Projects starts with the fundamentals of turning on the basic hardware and then provides complete, step-by-step instructions that allow almost anyone to use this low-cost hardware platform. You'll build projects that can move using DC motors, walk using servo motors, and then add sensors to avoid barriers. You'll also learn how to add more complex navigational techniques such as GPRS so that your robot won't get lost. « less

A cell phone’s roaming feature allows the user to get service when traveling beyond the boundaries of his/her service provider. Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological more » problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services. « less

IP, UMTS, EGPRS and ATM
The merging of voice and data on a single network opens powerful new possibilities in communications. Only a fundamental understanding of both technologies will ensure you are equipped to maximise their full potential. "Convergence Technologies for 3G Networks" describes the evolution from cellular to more » a converged network that integrates traditional telecommunications and the technology of the Internet. In particular, the authors address the application of both IP and ATM technologies to a cellular environment, including IP telephony protocols, the use of ATM/AAL2 and the new AAL2 signalling protocol for voice/multimedia and data transport as well as the future of the UMTS network in UMTS Release 5/6 All-IP architecture."Convergence Technologies for 3G Networks" explains the operation and integration of GSM, GPRS, EDGE, UMTS, CDMA2000, IP, and ATM. It provides practical examples of 3G connection scenarios. It describes signalling flows and protocol stacks. It covers IP and ATM as used in a 3G context. It addresses issues of QoS and real-time application support. It includes IP/SS7 internetworking and IP softswitching. It outlines the architecture of the IP Multimedia Subsystem (IMS) for UMTS. "Convergence Technologies for 3G Networks" is suited for professionals from the telecommunications, data communications and computer networking industries. « less

A Companion to the Specifications
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 more » 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. « less

GPRS is a packet based wireless communication service that offers data rates from 9.05 up to 171.2 Kbps and continuous connection to the Internet for mobile phone and computer users. GPRS is based on GSM communications and complements existing services such as circuit switched cellular phone connections more » and the Short Message Service (SMS). GPRS represents the bridge between 2G and 3G mobile telecommunications and is commonly referred to as 2.5G. Implementation of GPRS requires modification of the existing GSM networks in that GSM is a circuit switched technology while GPRS is packet oriented. GPRS enables packet data (the same as is used by an Ethernet LAN, WAN or the Internet) to be sent to and from a mobile station - e.g. mobile phone, PDA or Laptop. WAP and SMS can also be sent using GPRS and individuals working with GPRS need to learn and understand how the mobile stations, the air interface, network architecture, protocol structures and signalling procedures must be modified. GPRS offers much higher data rates than GSM and can be combined with 3G technologies such as EDGE to give even higher bit-rates. It offers many benefits for customers and network operators: such as volume (rather then time) dependent billing and more efficient use of network resources. « less
