National Wireless Communications Technology
Roadmap
  • The wireless communication sector represents one
    of the most important arenas of research and
    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.

National Wireless Communications Technology
Roadmap
  • The National Wireless Communications Technology
    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
Roadmap
  • The roadmap could serve as the basis to drive a
    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.

6
National Wireless Communications Technology
Roadmap
  • This roadmap will provide insights to the local
    academics and the researchers to work on
    technologies of the future.
  • The collective belief is that this roadmap will
    serve as a useful tool for carrying out RD in
    wireless communications technologies, based on
    trends and challenges, to enable Malaysia to be
    at par with other developing countries.

7
Trends in Communications and Media Technology,
Applications and Use
  • Trends in Communications and Media Technology,
    Applications and Use provides an overview of
    infrastructure, applications, social and economic
    trends developments, and anticipated
    developments over the next five to ten years.
  • The report focuses on developments since the
    release of Top Six Trends in Communications and
    Media Technologies, Applications and Services
    Possible Implications, in May 2008. Some
    continuity is provided through references to
    incremental advances in trends and developments
    identified previously.

8
Trends in Communications and Media Technology,
Applications and Use
  • 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.

9
Trends in Communications and Media Technology,
Applications and Use
  • This overview section also provides a high-level
    outline of potential regulatory issues arising
    from developments in technology and use.
  • The views set out in this report are not put
    forward as predictions and there is no attempt to
    pick technology winners or losers. The report
    contributes to work ACMA is undertaking to inform
    its understanding of the operation of regulation
    in the communications and media markets and as
    part of its statutory responsibilities to be
    informed and advise on technology developments
    and service trends.

10
Trends in Communications and Media Technology,
Applications and Use
  • It offers an opportunity to identify and engage
    with change, and to anticipate the need for
    possible action by ACMA.
  • Research was conducted using desktop analysis
    over the period April to November 2008, focusing
    on developments of significance reported over the
    period. ACMA will continue to update this report
    regularly and welcomes your feedback.

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.
