  • Coordinated+Multi-Point

    Mobile communication has gained significant importance in Today’s society. As of 2010, the number of mobile phone subscribers has surpassed 5 billion [ABI10], and the global annual mobile revenue is soon expected to top $1 trillion [Inf10]. While these numbers appear promising for mobile operators at first sight, the major game-changer that has come up recently is the fact that the market is more and more driven by the demand for mobile data traffic [Cis10].

  • Core+and+Metro+Networks

    It is commonly accepted Today that optical fiber communications have revolutionized telecommunications. Indeed, dramatic changes have been induced in the way we interact with our relatives, friends, and colleagues: we retrieve information, we entertain and educate ourselves, we buy and sell, we organize our activities, and so on, in a long list of activities. Optical fiber systems initially allowed for a significant curb in the cost of transmission and later on they sparked the process of a major rethinking regarding some, generation-old, telecommunication concepts like the (OSI)-layer definition, the lack of cross-layer dependency, the oversegmentation and overfragmentation of telecommunica- tions networks, and so on.

  • EMI+Protection+for+Communication+Systems

    Communication Today is not as easy as it was in the past. Protecting numerous com- munication services, which are operating in the same or adjacent communication channels, has become increasingly challenging. Communication systems have to be protected from both natural and manmade interference. Electromagnetic interfer- ence can be radiated or conducted, intentional or unintentional.

  • From GSM to LTE-Advanced Pro and 5G

    Wireless technologies like GSM, UMTS, LTE, Wireless LAN and Bluetooth have revolutionized the way we communicate by making services like telephony and Internet access available anytime and from almost anywhere. Today, a great variety of technical publications offer background information about these technologies but they all fall short in one way or another. Books covering these technologies usually describe only one of the systems in detail and are generally too complex as a first introduction. The Internet is also a good source, but the articles one finds are usually too short and super- ficial or only deal with a specific mechanism of one of the systems. For this reason, it was difficult for me to recommend a single publication to students in my telecommunication classes, which I have been teaching in addition to my work in the wireless telecommunication industry. This book aims to change this.

  • GSM, GPRS and EDGE Performance Evolution

    The wireless market has experienced a phenomenal growth since the first second- generation (2G) digital cellular networks, based on global system for mobile communications (GSM) technology, were introduced in the early 1990s. Since then, GSM has become the dominant global 2G radio access standard. Almost 80% of Today’s new subscriptions take place in one of the more than 460 cellular networks that use GSM technology. This growth has taken place simultaneously with the large experienced expansion of access to the Internet and its related multimedia services.

  • Interactivity+in+Social+Media

    When digital media is perceived only as a tool to deliver content the potential for using its affordances to explore meaning is lost. Rather than seeing media only as an access point, we can view it as a way to enhance the expressiveness of content. Today blogs, wikis, messaging, mash-ups, and social media (Facebook, Twitter, YouTube and others) offer authors ways to create narrative meaning that refl ects our new media culture. We can look to the past for similarities and parallels to better understand how to use social media as a creative tool with which to dialogue, collaborate, and create interactive narratives.

  • LTE, WiMAX and WLAN

    For nearly a hundred years telecommunications provided mainly voice services and very low speed data (telegraph and telex). With the advent of the Internet, several data services became mainstream in telecommunications; to the point that voice is becoming an accessory to IP-centric data networks. Today, high-speed data services are already part of our daily lives at work and at home (web surfing, e-mail, virtual private networks, VoIP, virtual meetings, chats...). The demand for high-speed data services will grow even more with the increasing number of people telecommuting.
