There are currently 3 "programming generations" of Atheros 802.11
wireless devices (some of these have multiple hardware implementations
but otherwise appear identical to users):
5210 supports 11a only
5211 supports both 11a and 11b
5212 supports 11a, 11b, and 11g

Fortran has always been the principal language used in the fields of scientific,
numerical, and engineering programming, and a series of revisions to the standard
defining successive versions of the language has progressively enhanced its power
and kept it competitive with several generations of rivals.
Beginning in 1978, the technical committee responsible for the development
of Fortran standards, X3J3 (now called J3), laboured to produce a new, much-
needed modern version of the language, Fortran 90. Its purpose is to "promote
portability, reliability, maintainability, and efficient execution... on a variety of
computing systems". The standard was published in 1991, and work began in
1993 on a minor revision, known informally as Fortran 95. Now this revised

Introduction
? ?
The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs
new Cortex family. With high performance and power efficiency, it targets a wide
variety of mobile and consumer applications including mobile phones, set-top boxes,
gaming consoles and automotive navigation/entertainment systems. The Cortex-A8
processor spans a range of performance points depending on the implementation,
delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding
consumer applications and consuming less than 300mW for low-power mobile devices.
This translates into a large increase in processing capability while staying with the
power levels of previous generations of mobile devices. Consumer applications will
benefit from the reduced heat dissipation and resulting lower packaging and integration
costs.

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.

At the time of writing, and to an extent never seen before, there is an expectation that
almost any information or service that is available through communication systems in
the office or home will be available wherever the user happens to be. This is placing
incredible demands on wireless communications and has been the driver for the gen-
esis and deployment of three generations of cellular systems in the space of 20 years.

Following chapter introduces the mobile communication, gives a short history of wireless
communication evolution, and highlights some application scenarios predestined for the
use of mobile devices. Cellular and wireless based systems related to different generations
of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and
WCDMA are also described by this Chapter. Much attention in this chapter is given
to express the wireless based networks, such as Wi-Fi and WiBro/WiMax, and wireless
broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter
with the future vision of mobile communication evolution

Mobile multimedia communication is increasingly in demand because of the basic need to communi-
cate at any time, anywhere, using any technology. In addition, to voice communication, people have a
desire to access a range of other services that comprise multimedia elements—text, image, animation,
high fidelity audio and video using mobile communication networks. To meet these demands, mobile
communication technologies has evolved from analog to digital, and the networks have passed through
a number of generations from first generation (1G) to fourth generation (4G).
