Mobile WiMAX at 3.5GHz Starting to Take Off
European operators are leveraging improvements in technology and 3.5GHz spectrum to offer true mobile WiMAX networks. New operators such as Imagine Communications in Ireland begin the launch of nation-wide coverage. More...Radio Waves That See Through Walls
University of Utah engineers showed that a wireless network of radio transmitters can track people moving behind solid walls. The system could help police, firefighters and others nab intruders, and rescue hostages, fire victims and elderly people who fall in their homes. It also might help retail marketing and border control. More...LTE Cellphones To Reach 56 Million In 2013
Forward Concepts has announced the publication of its newest in-depth annual study of the worldwide cellphone market, "Cellular Handset & Chip Markets '09". According to this report, HSPA+ is emerging in 2009, and will begin to displace WCDMA and HSDPA. LTE will begin in 2010, first as data cards and dongles. The forecast calls for LTE handsets to reach 56 million units in 2013 for a compound growth rate of 262%. More...Cell Phone Towers Can Help Predict The Next Big Flood
Researchers from Tel Aviv University say they have found a novel and reliable way to help predict the intensity of the next big flood, using common cell phone towers across the United States. Their model, which analyzes cell phone signals, adds a critical component to weather forecasting never before available. More...LTE - The UMTS Long Term Evolution
LTE - The UMTS Long Term Evolution: From Theory to Practice provides the reader with a comprehensive system-level understanding of LTE, built on explanations of the theories which underlie it. The book is the product of a collaborative effort of key experts representing a wide range of companies actively participating in the development of LTE, as well as academia. This gives the book a broad, balanced and reliable perspective on this important technology. Lucid yet thorough, the book devotes particular effort to explaining the theoretical concepts in an accessible way, while retaining scientific rigour. It highlights practical implications and draws comparisons with the well-known WCDMA/HSPA standards. The authors not only pay special attention to the physical layer, giving insight into the fundamental concepts of OFDMA, SC-FDMA and MIMO, but also cover the higher protocol layers and system architecture to enable the reader to gain an overall understanding of the system.Key Features:
- Draws on the breadth of experience of a wide range of key experts from both industry and academia, giving the book a balanced and broad perspective on LTE
- Provides a detailed description and analysis of the complete LTE system, especially the ground-breaking new physical layer
- Offers a solid treatment of the underlying advances in fundamental communications and information theory on which LTE is based
- Addresses practical issues and implementation challenges related to the deployment of LTE as a cellular system
- Includes an accompanying website containing a complete list of acronyms related to LTE, with a brief description of each
- This book is an invaluable reference for all research and development engineers involved in LTE implementation, as well as graduate and PhD students in wireless communications. Network operators, service providers and R&D managers will also find this book insightful.
