Today no one doubts that the introduction of GSM represented a revolution in mobile communications. As this book goes to press, there are more than 773 million GSM users worldwide and the number is growing by the minute. This revolution, which has taken
place over the last 12 years, has had an enormous impact on our daily lives. Mobile telephony has changed the way we communicate and the way we do business. Friends and colleagues can be reached almost anywhere at any time, we are no longer tied to desk-top machines for e-mails and faxes, and the mobiles themselves are replacing not only telephones but also dictaphones, personal organizers and phone books.
"Convergence" has been the buzzword in recent years. The above is just the beginning and GPRS is the key. As multifunction mobile devices replace cellphones, PDAs and notebook PCs, there will be an ever increasing demand for bandwidth. Home Internet
users are used to the level of service offered by 64 kbits?1 ISDN or the higher rates offered by the various DSL services. These users will increasingly demand the same level of service from their mobiles, and as the volume of users goes up, content and service providers will respond and the network operators will have to provide the capacity. Originally, 3G was seen as the means to satisfy the demand for bandwidth and GPRS was viewed by many simply as a stepping stone on the way from narrowband GSM to wideband UMTS. However, the worldwide delay in 3G rollout has led to GPRS being seen in a different light, particularly with the development of E-GPRS. The promise of low-cost reliable mobile Internet access has led to many operators implementing GPRS, but, whereas GSM was seen as a communications technology, GPRS is seen more as an enabling technology. The ability to run an application on a mobile device that can send and receive packet data at high speed makes possible such things as mobile Internet, remote device control, multi-player gaming, location-dependent information services, and m-commerce.
GPRS will continue to change the way we live, just as GSM has already done.

Internet without wires. Think about that for a minute. All of the entertainment, utility, and performance of the Internet yours, without being tied to a desk.Without even being tied to the home or office. Internet without wires...anywhere! Wireless is a growing revolution changing the way people communicate and share ideas. From cell phones to PDAs to mobile computers, wireless access puts you instantly in touch with millions of other people around the planet.Wi-Fi, in particular, is changing how people access the Internet from laptops and PDAs. It’s emerging as an alternative for cellular service, and it may even replace regular telephone lines as voice conversations begin to be re-routed over Wi-Fi networks in larger numbers. Wi-Fi is that subset of wireless communications designed for high-speed Internet access. Sometimes simply referred to as “wireless,” or known by its many-lettered specification IEEE 802.11b, a, g, and so on,Wi-Fi allows compatible devices to connect without cables or physical connections.
With speeds far in excess of most cable modem, DSL, and even T1 service,Wi-Fi is rapidly becoming the standard for Internet access. The store shelves are flooded with Wi-Fi access points, clients, music players, network hubs, and printers, and myriad other consumer devices sport Wi-Fi access.Take the Xbox, Playstation 2, and TiVo-these all have Wi-Fi ability now. Remember when people were saying how everything in the house will eventually be wired? How anything from a toaster or refrigerator to a stereo system or television would have Internet access? Well, it’s been some time coming, but with wireless in the home, these are now possibilities. Refrigerators are being sold with Wi-Fi connections, and several products will now connect your digital media from your computer to your television over Wi-Fi. I wonder when my toaster will send me a wireless e-mail when the toast pops?
Wireless is awesome, but it is also somewhat limited. The hardware you can buy in the store is mass-marketed and mass-produced. So it doesn’t have that extra edge that power users are looking for. Extra edges like longer range, sharing with friends, saying no to power lines, and finding every access point on your street can be yours with the projects in this book.
Wi-Fi Toys was written to help you take wireless to the next level. Go beyond the user manual and build your own projects using this book as your guide.
Few things are more liberating than a Wi-Fi connection.

The Internet era started in 1969. A family tree of the Internet is shown in Figure 1.1. The key driver for the Internet protocol (IP)-based network is a common application and service environment across multiple types of networks. In fact, the IP has created an open platform for innovative, flexible, and fast service creation, has enabled existing services to be supported, and has provided IP-based mobility for all types of wired and wireless transport in both the access network and the core network.
The target setting is to (1) create a world class all-IP system with rapid time-to-market and future-proof design, (2) enable flexibility for providing new, revolutionary services while ensuring smooth network evolution and service continuity, (3) provide access independent design for globally seamless services, and (4) enable growth of revenue-generating systems now by leveraging the newly emerged wireless data market.

This isn’t the kind of book you pick up and read from start to finish, as if it were a cheap novel. If I ever see you reading it at the beach, I’ll kick sand in your face. This book is more like a reference, the kind of book you can pick up, turn to just about any page, and start reading. It has 30 chapters, each one covering a specific aspect of networking - such as printing on the network,
hooking up network cables, or setting up security so that bad guys can’t break in. Just turn to the chapter you’re interested in and start reading.
Each chapter is divided into self-contained chunks, all related to the major theme of the chapter. For example, the chapter on hooking up the network cable contains nuggets like these:
- What Is Ethernet?
- All About Cabling and Stuff
- Attaching Connectors to UTP Cable
- Hubs and Switches
- Wall Jacks and Patch Panels
You don’t have to memorize anything in this book. It’s a “need-to-know” book: You pick it up when you need to know something. Need to know what 100BaseT is? Pick up the book. Need to know how to create good passwords?
Pick up the book. Otherwise, put it down and get on with your life.

Welcome to Wireless Home Networking For Dummies. Wireless networking for personal computers is not really a new idea; it’s been around for at least five years. The emergence of an industry standard, however, has caused the use of wireless networking technology to explode.
One of the most appealing things about the current crop of wireless networking equipment is the ease with which you can set up a home network, but its reasonable price might be the most attractive aspect of all. Setting up a wireless home network can be both inexpensive and easy. In some cases, it’s almost as simple as opening the box and plugging in the equipment; however, you can avoid many gotchas by doing a little reading beforehand. That’s where this book comes in handy.

В предлагаемой книге авторы постарались отразить наиболее важные на их взгляд проблемы преобразования сетей связи общего пользования в пакетные. Начало книги посвящено анализу трафика на сетях связи Российской Федерации, в дальнейшем уделено внимание сетевым вопросам пакетизации сетей и построению систем коммутации. Как основные элементы модернизации сети связи общего пользования, описываются мультисервисные узлы и сигнальные коммутаторы. Подробно рассмотрены также основные новые протоколы, обеспечивающие функционирование пакетной сети общего пользования.
В книге также рассматривается вопрос организации взаимодействия между административными доменами провайдеров, без которого пользователи оказываются практически изолированными в пределах различных доменов. Организация взаимодействия доменов требует обмена служебной информацией посредством определенного междоменного протокола OSP, применению которого также уделено некоторое внимание.
Авторами также сделана попытка определить основные терминологические аспекты применительно к рамкам рассмотрения предлагаемой вниманию читателей работы.
