This textbook is appropriate for engineers employed in the industry (or students planning a career) of creating network devices, primarily base stations and cell phones. This book is full of math formulas which will only be of interest to engineers.
This book does NOT address the health concerns of all of this energy being beamed around and absorbed by humans in everyday life. The focus of this book is 99% on energy usage reduction.
For those not directly involved in the technical aspects, many of the chapters present very interesting statistics. Some of the interesting statistics I found:
* Incredible growth in the cell phone market - this isn't surprising but some of the statistics are impressive such as AT&T reporting a 30 fold traffic growth from Q3 2009 to Q3 2010.
* Information and Communications Technologies (ICT) industry has 25% of the 2007 carbon footprint for cars worldwide and is similar to the entire aviation industry.
* A single 10 square foot solar panel can generate 100 to 200 watts of power.
* Three percent of the sun's energy to the earth is converted to wind energy. If only 3% of wind power was converted to electricity it would meet the world's total current energy requirements.
* There are currently (probably 2010 data considering the delay between authoring the book and publishing it) more than 4 million base stations each consuming an average of 25 MWh per year.
* In 2007, four Chinese operators consumed 20 billion KWh, which is the equivalent to 8 million tons of coal combustion.
The advantages of using solar and wind power for base stations is discussed. This will have great benefit for deployment in areas which aren't covered by the current power grid. (you may be surprised to know that many of the base stations are currently powered by batteries - these are challenging to maintain!)
Although this textbook is clearly for engineers in the network communications field, anyone interested in alternative power will also be interested in the information about alternative energy.
Very clever ideas are discussed, like a mobile phone intelligently delaying transmission until it is closer to the base station (detecting that a car is traveling and constantly changing it's distance to different base stations).
Page 84 has a nice graph showing the breakdown of mobile internet traffic growth projected for 2010, 2011, 2012, 2013, 2014 and 2015. If you don't think smartphones are big business now, reading this book will convince you this market is exploding and will be unbelievably larger within the next three years.
The book is split into five parts:
Part I - Communication architectures and models for green radio networks
Part II - Physical communications techniques for green radio networks
Part III - Base station power-management techniques for green radio networks
Part IV - Wireless access techniques for green radio networks
Part V - Green radio test-bed, experimental results, and standardization activities
