The definitive assessment of how wireless communications will evolve over the next 20 years.
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 Ph D 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.
