Wireless Communications: The Future

Wireless Communications: The Future

---

Predicting the future is an essential element for almost everyone involved in the wireless industry. Manufacturers predict the future when they decide on product lines to develop or research to undertake, operators when they buy licences and deploy networks, and academics when they set PhD topics. Wireless Communications: The Future provides a solid, clear and well-argued basis on which to make these predictions.
Starting with a description of the current situation and a look at how previous predictions made in 2000 have fared, the book then provides the contributions of six eminent experts from across the wireless industry. Based on their input and a critical analysis of the current situation, it derives detailed forecasts for 2011 through to 2026. This leads to implications across all of the different stakeholders in the wireless industry and views on key developments.
Presents clear and unambiguous predictions, not a range of scenarios from which the user has to decide
Includes chapters covering existing wireless systems which provide solid tutorial material across a wide range of wireless devices
Offers a range of views of the future from high profile contributors in various areas of the industry and from around the globe, including contributions from Vodafone and Motorola
Provides a comprehensive guide to current technologies, offering keen analysis of key drivers, end user needs and key economic and regulatory constraints
This book, compiled by a renowned author with a track record of successful prediction, is an essential read for strategists working for wireless manufacturers, wireless operators and device manufacturers, regulators and professionals in the telecoms industry, as well as those studying the topic or with a general interest in the future of wireless communications.

Network Troubleshooting Tools

Network Troubleshooting Tools

Book description
Network Troubleshooting Tools helps you sort through the thousands of tools that have been developed for debugging TCP/IP networks and choose the ones that are best for your needs. It also shows you how to approach network troubleshooting using these tools, how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise so you can solve them more effectively.
Over the years, thousands of tools have been developed for debugging TCP/IP networks. They range from very specialized tools that do one particular task, to generalized suites that do just about everything except replace bad Ethernet cables. Even better, many of them are absolutely free. There’s only one problem: who has time to track them all down, sort through them for the best ones for a particular purpose, or figure out how to use them? Network Troubleshooting Tools does the work for you–by describing the best of the freely available tools for debugging and troubleshooting. You can start with a lesser-known version of ping that diagnoses connectivity problems, or take on a much more comprehensive program like MRTG for graphing traffic through network interfaces. There’s tkined for mapping and automatically monitoring networks, and Ethereal for capturing packets and debugging low-level problems. This book isn’t just about the tools available for troubleshooting common network problems. It also outlines a systematic approach to network troubleshooting: how to document your network so you know how it behaves under normal conditions, and how to think about problems when they arise, so you can solve them more effectively. The topics covered in this book include:
* Understanding your network
* Connectivity testing
* Evaluating the path between two network nodes
* Tools for capturing packets
* Tools for network discovery and mapping
* Tools for working with SNMP
* Performance monitoring
* Testing application layer protocols
* Software sources
If you’re involved with network operations, this book will save you time, money, and needless experimentation.
