Writing essays and dissertations can be a major concern for overseas students studying at English-medium colleges and universities. Virtually all COURSEs contain a large degree of written assessment and it is essential to ensure that your writing skills meet the necessary standard. Academic Writing is a new kind of writing COURSE for all international students who have to write exams or COURSEwork in English. This practical book thoroughly explains the writing process and covers all the key writing skills.
A decade ago, I first wrote that people moved, and networks needed to adapt to the
reality that people worked on the go. Of COURSE, in those days, wireless LANs came
with a trade-off. Yes, you could use them while moving, but you had to trade a great
deal of throughput to get the mobility. Although it was possible to get bits anywhere,
even while in motion, those bits came slower. As one of the network engineers I worked
with put it, “We’ve installed switched gigabit Ethernet everywhere on campus, so I
don’t understand why you’d want to go back to what is a 25-megabit hub.” He un-
derestimated the allure of working on the go.
The core thrust of architecture has been to define core business requirements,
and then construct the IT solution to meet those requirements, typically as
instances of software. While this seems like a simple concept, many in enter-
prise IT went way off COURSE in the last 10 to 15 years.
This is the second edition of a textbook that is intended for a senior or graduate-level
COURSE in an electrical engineering (EE) curriculum on the subject of the analysis of
multiconductor transmission lines (MTLs). It will also serve as a useful reference
for industry professionals.
Throughout the COURSE of my work in multihop mobile ad hoc networks (MANET)
over the last several years, I reached the conclusion that mobility models and perfor-
mance metrics need to be treated in detail in designing these networks that are the
ultimatefrontierinwirelesscommunications. Awidevarietyofmobilitymodelscan
be used by mobile nodes.
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.
Do you have a mobile phone? We think you probably do, one way or another. We
would also guess that you might use it for many diff erent things in the COURSE of your
everyday life—as a telephone certainly, but also as an address book, as a clock or
watch, as a camera, or now as a connection to your computer, email and the internet.
Th ere will be a range of people you use it to contact (or not), and various strategies
you use to take calls—or send texts, or take photos, or receive emails, or search online
(or not, in diff erent situations). Th ere are also likely to be a range of social relation-
ships in your life that your mobile phone helps to maintain—or disrupts, or inter-
venes in, or makes possible, or complicates, or just plain helps to handle.
The last decade proved to be hugely successful for the mobile communications industry,
characterised by continued and rapid growth in demand, spurred on by new technological
advances and innovative marketing techniques. Of COURSE, when we refer to mobile commu-
nications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the
mobile-satellite industry over the last decade, although eventful, has, at times, been more akin
to an out of control roller coaster ride.
This edition updates and continues the series of books based on the residential
COURSEs on radiowave propagation organised by the IEE/IET.
The first COURSE was held in 1974, with lectures by H. Page, P. Matthews,
D. Parsons, M.W. Gough, P.A. Watson, E. Hickin, T. Pratt, P. Knight, T.B. Jones,
P.A. Bradley, B. Burgess and H. Rishbeth.
