"This book is an excellent summary of existing literature on Green Communications from a communications theorist point of view. It can be extremely valuable to researchers in this emerging area." - Vahid Tarokh, Harvard University
"is an excellent snapshot of the state of green in wireless networking, and it is a nice overview of who is doing what and where in the field." - Alfy Riddle, IEEE Microwave Magazine
"This is one of the first books related to the area of green wireless communication. It provides a good overview of different research works carried out independently by various groups. Although individual articles are very interesting, I miss a more holistic view..."
Michal Wagrowski, IEEE Communications Magazine, August 2013
"This book contains contributions from almost 60 scientists and engineers in academia and industry. Green Radio Communication Networks is an excellent snapshot of the state of green in wireless networking, and it is a nice overview of who is doing what and where in the field."
Presenting state-of-the-art research on green radio communications and networks, this book is a comprehensive treatment for researchers and professionals working in wireless communication. It summarizes existing and ongoing research on different aspects of energy-efficient technologies and serves as a one-stop reference of essential information for future generation cellular wireless systems.See all Product Description

I was especially impressed with how the book was broken up into five sections. These segments range from Communication Architectures and Models for Green Radio Networks to Wireless Access Tehniques for Green Radio Networks. The chapters are well paced and the techniques provided in them are easy to follow and understand.
I highly recommend this textbook for either beginner like myself or researchers who would like to add to their well of knowledge. This is a highly helpful book and will be appreciated by anyone interested in this field.
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
The energy used by the radio network can be divided into that consumed by the wireless devices, mostly cellphones, and that by the basestations and other fixed location entities that perform the wired communication. The average reader is surely well aware of the battery capacity of her cellphone. But the book tends to focus on minimising consumption by power saving methods at the basestation. Chapter 2 gives an example of a basestation that uses a wind mill and solar panels to power itself. This may be well suited for when it is located in remote areas or where the electric grid is unreliable.
The level of discussion is sophisticated. The chapters are essentially research papers at the graduate level for electrical and radio engineers and computer scientists versed in information theory. There are extensive forays into the modelling of channel capacity, especially for a dense wireless system.
The book differs from customary texts on radio engineering inasmuch as the primary driver of the many analyses in it is energy minimisation. I recall from earlier texts that those rarely took this as the main constraint. Instead, they might have used the maximising of the channel usage or capacity. Or the minimising of the bit error rate. Which is perhaps equivalent to maximising capacity.
