Ground-breaking resource offers you a detailed description and specifications for EDGE, a critical system for web browsing and multimedia messaging in the burgeoning field of mobile internet technology.

GSM, GPRS and EDGE Performance - Second Edition provides a complete overview of the entire GSM system. GSM (Global System for Mobile Communications) is the digital transmission technique widely adopted in Europe and supported in North America. It features comprehensive descriptions of GSM’s main evolutionary milestones - GPRS, (General Packet Radio Services) is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the Internet for mobile phone and computer users. AMR and EDGE (Enhanced Data GSM Environment), and such developments have now positioned GERAN (GSM/EDGE Radio Access Network) as a full 3G radio standard. The radio network performance and capabilities of GSM, GPRS, AMR and EDGE solutions are studied in-depth by using revealing simulations and field trials.
Cellular operators must now roll out new 3G technologies capable of delivering wireless Internet based multimedia services in a competitive and cost-effective way and this volume, divided into three parts, helps to explain how:

Bluetooth is a standard for wireless integration of small devices. Bluetooth for Java
is specifically about using Java to program Bluetooth-enabled devices.
The specification for Java and Bluetooth was released in February.
However, vendors are implementing the specification now and most won’t
be ready/available until Fall 2002. Bluetooth is a technology for
wireless communication. It is similar in functionality to the way
laptops connect to the Internet from home/office, but is typically used
for short burst communications instead of a continuous connection.
Because of this difference, Bluetooth is more typically found supported
in wireless phones and personal devices. What Bluetooth for Java
offers is not an overview of what Bluetooth is. Instead, Bruce Hopkins
and Ranjith Antony describe how to develop wireless Java applications
using Bluetooth for a variety of platforms. This includes an API
overview of the Java library, development of Bluetooth-based services,
highlights of security concerns, and walkthroughs for development with
some of the different tools available. Programs will not be just J2ME
(micro devices) based, but will also be for J2SE (client/desktop).

Mobile Interaction Design shifts the design perspective away from the technology and concentrates on usability; in other words the book concentrates on developing interfaces and devices with a great deal of sensitivity to human needs, desires and capabilities.
Presents key interaction design ideas and successes in an accessible, relevant way
Exercises, case studies and study questions make this book ideal for students.
Provides ideals and techniques which will enable designers to create the next generation of effective mobile applications.
Critiques current mobile interaction design (bloopers) to help designers avoid pitfalls.
Design challenges and worked examples are given to reinforce ideas.
Discusses the new applications and gadgets requiring knowledgeable and inspired thinking about usability and design.
Authors have extensive experience in mobile interaction design, research, industry and teaching

Two
of the world�s most powerful technology trends, the Internet and mobile
communications, are redefining how and when people access information.
With the majority of information and new services being deployed over
IP, the use of devices such as cellular phones, PDAs, and laptops for
accessing data networks is pushing the need for �always on� IP
connectivity. The evolution of mobile computing points to a coming
together of the best of desktop computing and cellular
communications�the predictability and “always connected” experience of
the desktop combined with the ease of use and mobility of the cell
phone.

�

One
challenge to mobile data communication is moving data across different
networks. The solution to this problem is a standards-based protocol:
Mobile IP. Mobile IP is an open standard that allows users to keep the
same IP address, stay connected, and maintain ongoing applications
while roaming between IP networks.

�

Mobile IP Technology and Applications
is the first book to address the practical application of Mobile IP in
real-world environments. Cisco IOS� Mobile IP configuration,
troubleshooting, and management are covered in depth and supported by
real-world examples. Mobility solutions addressed in this book include
enterprise campus wireless LANs and metropolitan mobility for both
individual devices and whole networks. Each example is designed to
teach configuration, management, and troubleshooting in a manner that
is directly applicable to common mobility needs.

A guide to programming Symbian OS smartphones using OPL (The Open Programming Language): a simple to learn, open-source scripting language, ideal for fast-track development of enterprise applications. This book provides a hands-on development environment for both the experienced and aspiring programmer, demonstrating the ease of use of Symbian OS technologies through the utilization of OPL. OPL has a shallow learning curve which allows bespoke corporate tools to be developed in house by technical staff who aren’t necessarily trained programmers. Rapid Mobile Enterprise Development For Symbian OS provides a clear guide on both how to program, and understanding the structure of the language through a keyword dictionary. Any bespoke OPL application can grow with a company, eventually providing access to more advanced C++ code through OPX extensions. From the home programmer who wants to do more with their phone, to the enterprise developer, Rapid Mobile Enterprise Development For Symbian OS is the ideal starting point for simple, innovative application design using OPL.
