Two IMPortant microwave remote sensors are the radar and the radiometer. There have been a number of books written on various aspects of radar, but there have been only a few written on microwave radiometers, especially on sub- jects of how to design and build radiometer systems. This book, which is the second edition of a book originally published in 1989, attempts to fill this void.

Licensed spectrum remains 3GPP operators’ top priority to deliver advanced services and user experience Opportunistic use of unlicensed spectrum is becoming an IMPortant complement for operators to meet the growing traffic demand Moving forward 3GPP operators will have two options to offload traffic to unlicensed spectrum: 1. Wi-Fi (via LTE/Wi-Fi interworking) 2. LTE over unlicensed It will then be up to each individual operator to choose which approach to use, which will depend on a number of factors

YoumayaskwhyIwrotethisbook.Therearemany,manypersonalreasonsaswithanyauthor I suppose. The first two reasons and probably the most IMPortant are my love of flying and my love of radio engineering. This may sound rather dull but I love flying in any machine be it balloon, glider, propeller aircraft, microlight through to airline jets and the experience of it. The more I do it the more I feel I understand it.

Emergingmarketshaveseenanunprecedentedgrowthinthelastfewyears.Theoperatorfocus has been on giving complete coverage to all regions (urban to rural) and to subscription to all – people from the highest to the lowest income groups. When the idea is taking coverage for the remotest of the regions and getting the ‘unconnected–connected’, technology and business modelling are two IMPortant focus areas.

How will future generations refer to our times? Will it be known as one of space exploration, genetics, atomic energy or computing? Possibly, but I think it is more likely to be ‘The age of communications’. Not since printed books and newspapers were first introduced has there been such an explosion of communication. None of this technology could function without modern cables and, just as IMPortant, competent installers.

When the authors of this book asked me to write the foreword of their work on the digital enterprise, I immediately thought that it was one more document on a fashionable topic in the technology and the business world of the 21st Century often addressed by consulting firms, some of which have aspired to become experts on the subject. However, a more careful observation reveals that an issue more IMPortant than the sole subject of the digital enterprise is: “Is your company fully operational?”, because this is the real topic.

A series of features makes the mobile telecommunications industry an interesting field of investigation for economists: the industry is experi- encing veryfastmarketgrowthcombinedwithrapidtechnological change; regulatory design in setting market structure is playing a very IMPortant role; and oligopolistic competition is unfolding under various forms. The number of subscribers to mobile networks is growing at a rapid rate on a worldwide basis, as shown in figure 1.1.

Providing QoS while optimizing the LTE network in a cost efficient manner is very challenging. Thus, radio scheduling is one of the most IMPortant functions in mobile broadband networks. The design of a mobile network radio scheduler holds several objectives that need to be satisfied, for example: the scheduler needs to maximize the radio performance by efficiently distributing the limited radio re- sources, since the operator’s revenue depends on it.

Thisbookfocusesontheemergingresearchtopic‘green(energy-efficient)wirelessnetworks’ that has drawn huge attention recently from both academia and industry. This topic is highly motivated due to IMPortant environmental, financial and quality-of-experience (QoE) consid- erations.Duetosuchconcerns,varioussolutionshavebeenproposedtoenableefficientenergy usage in wireless networks, and these approaches are referred to as green wireless communi- cations and networking. The term ‘green’ emphasizes the environmental dimension of the proposed solutions. Hence, it is not sufficient to present a cost-effective solution unless it is eco-friendly.

Your Cisco Networking Academy Course Booklet is designed as a study resource you can easily read, high- light, and review on the go, wherever the Internet is not available or practical: ■ The text is extracted directly, word-for-word, from the online course so you can highlight IMPortant points and take notes in the “Your Chapter Notes” section. ■ Headings with the exact page correlations provide a quick reference to the online course for your class- room discussions and exam preparation. ■ An icon system directs you to the online curriculum to take full advantage of the images, labs, Packet Tracer activities, and dynamic Flash-based activities embedded within the Networking Academy online course interface.
