| at&t weak signal solution: Mobile Networks Made Easy A Ghayas, Commsbrief Limited, 2017-08-28 Mobile cellular networks can be hard to understand especially for those who are new to the industry. Even if you are not that new, the nature of this high-tech industry can pose new challenges for you every now and then. The one thing that we all do when presented with such challenges is to go online and do some research. Interestingly, the problem that we usually come across is not the lack of information but actually the abundance of information. There is so much information available online that it becomes really hard to cut to the chase especially if you don't have a lot of time to do the research. Why this book?The intention of this book is to save time for those looking for professional information quickly. It means that you don't have to read hundreds of pages to develop a basic understanding of mobile networks. It is written by someone who already has spent a lot of time reading hundreds (or thousands) of pages of academic and professional documentation whilst working full-time in the industry just to come to this conclusion: I wish someone had explained it in a simpler and quicker way. Hopefully, the 50 pages of this book give you the core understanding that you must develop before getting into the details of mobile networks. This book is mainly for those new and prospective telecom professionals who would like to develop industry-specific understanding of the mobile networks. It can also be used by young graduates or students ahead of a job or apprenticeship interview. It covers the following topics: What is a mobile network?Fundamental concepts1G-First Generation2G-Second Generation3G-Third Generation4G-Fourth GenerationMacrocellsSmall cellsMicrocellPicocellFemtocellMobile phoneFeature phoneSmartphoneIMEISIM cardIMSISiteUplinkDownlinkARFCNHandoverBTSNode BeNodeBBSCRNCBSS (GSM)RANBackhaulMobile core networkMSCEPCHLR/HSSSGSNGGSNOSSBSS |

| at&t weak signal solution: Multimedia Richard Wise, 2005-07-15 Multimedia: A Critical Introduction is a comprehensive guide to the new media form which has resulted from the application of computer technology to existing techniques of broadcasting and telecommunications transmission. The rapid growth of multimedia technologies such as the internet, e-mail and digital television holds the promise of a new 'information age' in which individual tastes are catered for, citizens become better informed, and new wealth is created. But are new media technologies really designed to achieve these utopian aims? Multimedia: a critical introduction provides a historical, cultural and political context to the development of multimedia, as both a technology and a concept. Individual chapters address: * the origins of multimedia in the unlikely interaction between the military and 1960s counter-culture: how the phenomenal US budgets allocated to US military research resulted in the microchip, and why the efforts of counter-culture computer hobbyists evolved into a multi-billion dollar industry. *the wider democratic and cultural implications of multimedia in the wake of the deregulation of the media industries by 'new right' governments in the 1980s, which has led to the domination of the media by transnational conglomerates. * issues of privacy and censorship in relation to new media, including discussion of cryptography, electronic surveillance, and attempts to regulate material such as pornography on the internet. * the use of digital technology to create special effects in feature films. |

| at&t weak signal solution: Submarine Cables and the Oceans L. Carter, 2009 There are many things and services in our everyday life that we take for granted, and telecommunications is one of them. We surf the internet, send emails to friends and colleagues abroad, talk to family members in foreign countries over the phone, book airline seats and make banking transactions without actually realizing and appreciating the sophisticated technology that enables us to do so. This report covers the history and nature of cables, their special status in international law, their interaction with the environment and other ocean users and, finally, the challenges of the future. It is an evidence-based synopsis that aims to improve the quality and availability of information to enhance understanding and cooperation between all stakeholders. UNEP-WCMC in collaboration with the International Cable Protection Committee and UNEP has prepared this new report to provide an objective, factual description of the sub-marine cable industry and the interaction of submarine telecommunications (which route 95% of all international communications traffic) with the marine environment. This important report seeks to focus and guide deliberations and decision making on the wise conservation and protection of the oceans in concert with their sustainable management and use. |
| at&t weak signal solution: Understanding the Linux Kernel Daniel Pierre Bovet, Marco Cesati, 2002 To thoroughly understand what makes Linux tick and why it's so efficient, you need to delve deep into the heart of the operating system--into the Linux kernel itself. The kernel is Linux--in the case of the Linux operating system, it's the only bit of software to which the term Linux applies. The kernel handles all the requests or completed I/O operations and determines which programs will share its processing time, and in what order. Responsible for the sophisticated memory management of the whole system, the Linux kernel is the force behind the legendary Linux efficiency. The new edition of Understanding the Linux Kernel takes you on a guided tour through the most significant data structures, many algorithms, and programming tricks used in the kernel. Probing beyond the superficial features, the authors offer valuable insights to people who want to know how things really work inside their machine. Relevant segments of code are dissected and discussed line by line. The book covers more than just the functioning of the code, it explains the theoretical underpinnings for why Linux does things the way it does. The new edition of the book has been updated to cover version 2.4 of the kernel, which is quite different from version 2.2: the virtual memory system is entirely new, support for multiprocessor systems is improved, and whole new classes of hardware devices have been added. The authors explore each new feature in detail. Other topics in the book include: Memory management including file buffering, process swapping, and Direct memory Access (DMA) The Virtual Filesystem and the Second Extended Filesystem Process creation and scheduling Signals, interrupts, and the essential interfaces to device drivers Timing Synchronization in the kernel Interprocess Communication (IPC) Program execution Understanding the Linux Kernel, Second Edition will acquaint you with all the inner workings of Linux, but is more than just an academic exercise. You'll learn what conditions bring out Linux's best performance, and you'll see how it meets the challenge of providing good system response during process scheduling, file access, and memory management in a wide variety of environments. If knowledge is power, then this book will help you make the most of your Linux system. |

| at&t weak signal solution: The Book of Broken Promises Bruce Kushnick, 2015-02-20 Broken Promises is the third book in a trilogy spanning 18 years. Bruce Kushnick, author, senior telecom analyst and industry insider, lays out, in all of the gory details, how America paid over $400 billion to be the first fully fiber optic-based nation yet ended up 27th in the world for high-speed Internet (40th in upload speeds). But this is only a part of this story. With over four million people filing with the FCC to 'Free the Net', one thing is abundantly clear -- customers know something is terribly wrong. Every time you pay your bills you notice that the price of your services keeps going up, you don't have a serious choice for Internet (ISP), broadband or cable service, much less competitors fighting for your business, or maybe you can't even get very fast broadband service. Worse, over the last few years, America's ISPs and cable companies have been rated the most hated companies in America. While Net Neutrality concerns (detailed in Broken Promises) are important, the actions are only a first step and will most likely be tied up in court for the next few years. More importantly, it does not resolve most of the customer issues and there is nothing else on the horizon that will fix what's broken. Broken Promises documents the massive overcharging and failure to properly upgrade the networks, the deceptive billing practices, the harms caused from a lack of competition, the gaming and manipulating of the regulatory system, from the states to the FCC, and exposes the companies' primary strategy: How much can we get away with? There has been little, if any, regard for the customers they serve.--From http://newnetworks.com/bookbrokenpromises/ --(viewed on June 12, 2015). |

| at&t weak signal solution: Mobile and Wireless Communications Salma Ait Fares, Fumiyuki Adachi, 2010-01-01 Mobile and wireless communications applications have a clear impact on improving the humanity wellbeing. From cell phones to wireless internet to home and office devices, most of the applications are converted from wired into wireless communication. Smart and advanced wireless communication environments represent the future technology and evolutionary development step in homes, hospitals, industrial, vehicular and transportation systems. A very appealing research area in these environments has been the wireless ad hoc, sensor and mesh networks. These networks rely on ultra low powered processing nodes that sense surrounding environment temperature, pressure, humidity, motion or chemical hazards, etc. Moreover, the radio frequency (RF) transceiver nodes of such networks require the design of transmitter and receiver equipped with high performance building blocks including antennas, power and low noise amplifiers, mixers and voltage controlled oscillators. Nowadays, the researchers are facing several challenges to design such building blocks while complying with ultra low power consumption, small area and high performance constraints. CMOS technology represents an excellent candidate to facilitate the integration of the whole transceiver on a single chip. However, several challenges have to be tackled while designing and using nanoscale CMOS technologies and require innovative idea from researchers and circuits designers. While major researchers and applications have been focusing on RF wireless communication, optical wireless communication based system has started to draw some attention from researchers for a terrestrial system as well as for aerial and satellite terminals. This renewed interested in optical wireless communications is driven by several advantages such as no licensing requirements policy, no RF radiation hazards, and no need to dig up roads besides its large bandwidth and low power consumption. This second part of the book, Mobile and Wireless Communications: Key Technologies and Future Applications, covers the recent development in ad hoc and sensor networks, the implementation of state of the art of wireless transceivers building blocks and recent development on optical wireless communication systems. We hope that this book will be useful for students, researchers and practitioners in their research studies. |

| at&t weak signal solution: Good Strategy Bad Strategy Richard Rumelt, 2011-07-19 Good Strategy/Bad Strategy clarifies the muddled thinking underlying too many strategies and provides a clear way to create and implement a powerful action-oriented strategy for the real world. Developing and implementing a strategy is the central task of a leader. A good strategy is a specific and coherent response to—and approach for—overcoming the obstacles to progress. A good strategy works by harnessing and applying power where it will have the greatest effect. Yet, Rumelt shows that there has been a growing and unfortunate tendency to equate Mom-and-apple-pie values, fluffy packages of buzzwords, motivational slogans, and financial goals with “strategy.” In Good Strategy/Bad Strategy, he debunks these elements of “bad strategy” and awakens an understanding of the power of a “good strategy.” He introduces nine sources of power—ranging from using leverage to effectively focusing on growth—that are eye-opening yet pragmatic tools that can easily be put to work on Monday morning, and uses fascinating examples from business, nonprofit, and military affairs to bring its original and pragmatic ideas to life. The detailed examples range from Apple to General Motors, from the two Iraq wars to Afghanistan, from a small local market to Wal-Mart, from Nvidia to Silicon Graphics, from the Getty Trust to the Los Angeles Unified School District, from Cisco Systems to Paccar, and from Global Crossing to the 2007–08 financial crisis. Reflecting an astonishing grasp and integration of economics, finance, technology, history, and the brilliance and foibles of the human character, Good Strategy/Bad Strategy stems from Rumelt’s decades of digging beyond the superficial to address hard questions with honesty and integrity. |

Today that number is less than one percent. What went so wrong? Losing the Signal is a riveting story of a company that toppled global giants before succumbing to the ruthlessly competitive forces of Silicon Valley. This is not a conventional tale of modern business failure by fraud and greed. The rise and fall of BlackBerry reveals the dangerous speed at which innovators race along the information superhighway. With unprecedented access to key players, senior executives, directors and competitors, Losing the Signal unveils the remarkable rise of a company that started above a bagel store in Ontario. At the heart of the story is an unlikely partnership between a visionary engineer, Mike Lazaridis, and an abrasive Harvard Business school grad, Jim Balsillie. Together, they engineered a pioneering pocket email device that became the tool of choice for presidents and CEOs. The partnership enjoyed only a brief moment on top of the world, however. At the very moment BlackBerry was ranked the world's fastest growing company internal feuds and chaotic growth crippled the company as it faced its gravest test: Apple and Google's entry in to mobile phones.
