  expansion in Malaysia. The last two decades has
  been considered to be the era of wireless
  communications being led by two major trends the
  outburst of wireless multiple access
  communications, offering mobility to the
  telephone users and the mobile multimedia. The
  increasing number of mobile teleco subscribers
  cause great concern to the research community and
  they are in the process of finding solutions to
  accommodate these customers.

  Roadmap serves as the basis to drive the national
  centers of excellence (CoEs) in the area of
  concern.
• The CoEs will be established based on the
  expertise available at RD organization.
• Moreover, the roadmap will serve as a guide to
  the Ministry of Science, Technology and
  Innovation (MOSTI) for approving research
  proposals seeking scientific and technical grants.

5
National Wireless Communications Technology

  concerted effort in RD activities in wireless
  communications nationwide
• As mentioned earlier, to be at the cutting edge
  of wireless technologies and hence, to excel in
  those areas, it is quintessential to identify the
  latest technology trends and challenges.
• Hence, it is necessary to keep this roadmap very
  much alive by updating it on a regular basis.

• This report includes recent developments and
  expectations in technologies, applications and
  use that were introduced in the May 2008 report,
  such as spectrum sharing, deep packet inspection,
  the semantic web and social web.
• While the primary focus of this report is on
  technology, a section on the social and economic
  implications of technology developments has been
  added. This new section recognises that the
  social and economic use of technology also
  enables innovation and change.

Evolution of Mobile Wireless Communication
Networks 1G to 4G

• The last few years have witnessed a phenomenal
  growth in the wireless industry, both in terms of
  mobile technology and its subscribers. There has
  been a clear shift from fixed to mobile cellular
  telephony, especially since the turn of the
  century.
• By the end of 2010, there were over four times
  more mobile cellular subscriptions than fixed
  telephone lines (see Fig. 1).

12
Evolution of Mobile Wireless Communication
Networks 1G to 4G

• Both the mobile network operators and vendors
  have felt the importance of efficient networks
  with equally efficient design.
• This resulted in Network Planning and
  optimization related services coming in to sharp
  focus 1, 7.
• With all the technological advances, and the
  simultaneous existence of the 2G, 2.5G and 3G
  networks, the impact of services on network
  efficiency have become even more critical.

13
Evolution of Mobile Wireless Communication
Networks 1G to 4G

• Many more designing scenarios have developed with
  not only 2G networks but also with the evolution
  of 2G to 2.5G or even to 3G networks. Along with
  this, inter-operability of the networks has to be
  considered 2.
• 1G refers to analog cellular technologies it
  became available in the 1980s. 2G denotes initial
  digital systems, introducing services such as
  short messaging and lower speed data.

14
Evolution of Mobile Wireless Communication
Networks 1G to 4G

• CDMA2000 1xRTT and GSM are the primary 2G
  technologies, although CDMA2000 1xRTT is
  sometimes called a 3G technology because it meets
  the 144 kbps mobile throughput requirement. EDGE,
  however, also meets this requirement. 2G
  technologies became available in the 1990s. 3G
  requirements were specified by the ITU as part of
  the International Mobile Telephone 2000
  (IMT-2000) project, for which digital networks
  had to provide 144 kbps of throughput at mobile
  speeds, 384 kbps at pedestrian speeds, and 2 Mbps
  in indoor environments.

15
Evolution of Mobile Wireless Communication
Networks 1G to 4G

• UMTS-HSPA and CDMA2000 EV-DO are the primary 3G
  technologies, although recently WiMAX was also
  designated as an official 3G technology. 3G
  technologies began to be deployed last decade.

16
eMobility Strategic Research Agenda 2008

• By the year 2020, mobile and wireless comm. will
  play a central role in all aspects of European
  citizens lives, not just telephony, and will be
  a major influence on European economy, wirelessly
  enabling every conceivable business endeavor and
  personal lifestyle. Following sentence
  articulates the essence of the future aims and
  vision The improvement of the individual's
  quality of life, achieved through the
  availability of an environment for instant
  provision and access to meaningful, multi-sensory
  information and content.

17
eMobility Strategic Research Agenda 2008

• Realization of this vision demands a major shift
  from the current concept of anywhere, anytime
  to a new paradigm of any network, any device,
  with relevant content and context in a secure and
  trustworthy manner.
• The future systems will be complex, consisting of
  a multitude of service and network types ranging
  across Wireless Sensor Networks (WSN), Personal
  Area, Local Area, Home Networks, Moving Networks
  to Wide Area Cellular Networks.

18
eMobility Strategic Research Agenda 2008

• The increasing dependency of society on such
  communication infrastructure requires
  considerations of new applications and
  requirements into their design as well as new
  research methodology to realize them.
• Research methodology proposed here is based on
  Europes unique strength and approach to research
  and development of telecommunication systems. It
  is captured in a new concept called SET Concept
  that underscores the need for a 3-dimensional
  vision of research activities that will deliver
  Simplicity, Efficiency and Trust.

19
eMobility Strategic Research Agenda 2008

• It will strongly advocate integrated research
  and end-to-end solutions. The Simplicity is
  to enable simple use of services, service
  deployment and enhancement and simple and
  self-optimizing operations, maintenance and
  upgrades. The Efficiency emphasizes on
  efficient use of networks all types of resources
  and more importantly the energy efficiency
  contributing towards a greener environment,
  whereas the Trust considers the new
  requirements and needs of modern societal
  dependency on use and full availability of such
  systems in carrying out their daily lives with
  robust security and resilience in face of variety
  of natural and man-made disasters.

20
eMobility Strategic Research Agenda 2008

• Several strategically important technologies and
  non-technical barriers have been identified and
  justifications provided for their considerations
  into future national and European research
  programs. The technological related chapters are
  complemented with further work on Flexible
  business infrastructures, demonstrating
  different business models and business interfaces
  that are envisaged in future.

21
Multiple Access Techniques for Wireless
Communication

• In wireless communications systems, it is often
  desirable to allow the subscriber to send
  simultaneously information to the base station
  while receiving information from the base
  station. For example, in conventional telephone
  systems, it is possible to talk and listen
  simultaneously, and this effect, called
  duplexing, is generally required in wireless
  telephone systems.
• Duplexing may be done using frequency or time
  domain techniques.

22
Multiple Access Techniques for Wireless
Communication

• Frequency division duplexing (FDD) provides two
  distinct bands of frequencies for every user. The
  forward band provides traffic from the base
  station to the mobile, and the reverse band
  provides traffic from the mobile to the base
  station. In FDD, any duplex channel actually
  consists of two simplex channels (a forward and
  reverse), and a device called a duplexer is used
  inside each subscriber unit and base station to
  allow simultaneous bidirectional radio
  transmission and reception for both the
  subscriber unit and the base station on the
  duplex channel pair.

23
Multiple Access Techniques for Wireless
Communication

• The frequency separation between each forward and
  reverse channel is constant throughout the
  system, regardless of the particular channel
  being used.
• Time division duplexing (TDD) uses time instead
  of frequency to provide both a forward and
  reverse link. In TDD, multiple users share a
  single radio channel by taking turns in the time
  domain. Individual users are allowed to access
  the channel in assigned time slots, and each
  duplex channel has both a forward time slot and a
  reverse time slot to facilitate bidirectional
  communication.

24
Multiple Access Techniques for Wireless
Communication

• If the time separation between the forward and
  reverse time slot is small, then the transmission
  and reception of data appears simultaneous to the
  users at both the subscriber unit and on the base
  station side.
• TDD allows communication on a single channel (as
  opposed to requiring two separate simplex or
  dedicated channels) and simplifies the subscriber
  equipment since a duplexer is not required.

25
The Mobile Communication Society A cross -
cultural analysis of available evidenceon the
social uses o f wireless communication technology

• Wireless communication technology is diffusing
  around the planet faster than any other
  communication technology to date. Because
  communication is at the heart of human activity
  in all domains, the advent of this technology,
  allowing multimodal communication from anywhere
  to anywhere where there is the appropriate
  infrastructure, is supposed to have profound
  social effects.

26
The Mobile Communication Society A cross -
cultural analysis of available evidenceon the
social uses o f wireless communication technology

• Yet, which kind of effects, under which
  conditions, for whom and for what is an open
  question.
• Indeed, we know from the history of technology,
  including the history of the Internet, that
  people and organizations end up using the
  technology for purposes very different of those
  initially sought or conceived by the designers of
  the technology.
• Furthermore, the more a technology is
  interactive, and the more it is likely that the
  users become the producers of the technology in
  its actual practice.

27
The Mobile Communication Society A cross -
cultural analysis of available evidenceon the
social uses o f wireless communication technology

• Therefore, rather than projecting dreams and
  fears on the kind of society that will result in
  the future from the widespread use of wireless
  communication, we must root ourselves in the
  observation of the present using the traditional,
  standard tools of scholarly research. People,
  institutions, and business have suffered enough
  from the unwarranted prophecies of futurologists
  and visionaries that project and promise whatever
  comes to their minds on the basis of anecdotal
  observation and ill understood developments.

28
The Mobile Communication Society A cross -
cultural analysis of available evidenceon the
social uses o f wireless communication technology

• Thus, our aim in this report is to ground an
  informed discussion of the social uses and social
  effects of wireless communication technology on
  what we know currently (2004) in different areas
  of the world. We would have like to consider
  exclusively information and analyses produced
  within the rigorous standards of academic
  research. This constitutes a good proportion of
  the material examined here. However, because of
  the novelty of the phenomenon and the slow motion
  of traditional academic research to uncover new
  fields of inquiry, the stock of contrasted
  knowledge on this subject is too limited to grasp
  empirically the emerging trends that are
  transforming communicative practices.

29
A Study Wireless Communication Domain

• Virtually every electronic device designed and
  manufactured today, whether be a domestic,
  medical, consumer, industrial or military
  product, is an embedded system. Complexity in
  design varies from low, with a single
  microcontroller chip, to very high with multiple
  units, peripherals and networks 1,2.
• In such a scenario wireless connectivity is one
  of the solutions that offers good amount of
  freedom and convenience. Short Range Wireless
  Systems are specialized programmable systems that
  are part of a larger system or a machine.

30
A Study Wireless Communication Domain

• This paper provides on overview of the
  Communication Techniques for Short Range Wireless
  Systems technologies that could be used with
  embedded systems for inter-device connectivity.
