    5G WIRELESS – A TRANSFORMATIVE,

    DISRUPTIVE TECHNOLOGY

    SUBMITTED BY – ABISHEK GOWDA B K (1SJ14IS001)


    INTRODUCTION TO 5G
    ■ 5G is the 5th generation mobile network. It is a new global
    wireless standard after 1G, 2G, 3G, and 4G networks. 5G
    enables a new kind of network that is designed to connect
    virtually everyone and everything together including
    machines, objects, and devices.
    ■ 5G wireless technology is meant to deliver higher multi-Gbps
    peak data speeds, ultra low latency, more reliability, massive
    network capacity, increased availability, and a more uniform
    user experience to more users.
    Currently, 5G is not a term officially used for any particular
    specification or in any official document yet made public by
    telecommunication companies or standardization bodies such as
    3GPP, WiMAX Forum or ITU-R. New 3GPP standard releases
    beyond 4G and LTE Advanced are in progress, but not considered
    as new mobile generations. The implementation of standards under
    a 5G umbrella would likely be around the year of 2020.
    How does 5G work?
    A mobile network has two main components, the ‘Radio
    Access Network’ and the ‘Core Network’.
    The Radio Access Network - consists of various types of
    facilities including small cells, towers, masts and dedicated
    in-building and home systems that connect mobile users
    and wireless devices to the main core network.
    Small cells will be a major feature of 5G networks
    particularly at the new millimeter wave (mmWave)
    frequencies where the connection range is very short. To
    provide a continuous connection, small cells will be
    distributed in clusters depending on where users require
    connection which will complement the macro network that
    provides wide-area coverage.
    The Core Network - is the mobile exchange and data
    network that manages all of the mobile voice, data and
    internet connections. For 5G, the ‘core network’ is being
    redesigned to better integrate with the internet and cloud
    based services and also includes distributed servers across
    the network improving response times (reducing latency).
    5G integration with 4G
    When a 5G connection is established, the User
    Equipment (or device) will connect to both the
    4G network to provide the control signalling
    and to the 5G network to help provide the fast
    data connection by adding to the existing 4G
    capacity.
    Where there is limited 5G coverage, the data is
    carried on the 4G network providing the
    continuous connection. Essentially with this
    design, the 5G network is complementing the
    existing 4G network
    Methodology
    The four step framework is as follows:
    Step I. User Background Analysis
    • 5G User Device and Capability Analysis
    • User Task Analysis (Videos, Data upload /download etc)
    Step II. Data flow Design Conceptualization
    • User Interface Design for data transactions
    • Selection of data parameters based on user requirements
    Step III. Iterative Prototype Implementation
    • User Data flow step by step implementation
    • User upload and download of data requirements for an application
    Step IV. Usability Evaluation
    • Evaluation of Simulation model using Matlab.
    • Evaluation of Data flow needs and fulfilment.
    Different case studies of Data flow such as simple, medium, huge data flow requirements can be studied. Step
    by step the data requirements can be simulated for complex needs like interactive and fast delivery of data for
    higher end applications like gaming and health industry.

    Scope
    5th generation technology is designed to provide incredible and remarkable data capabilities,
    unhindered call volumes, and immeasurable data broadcast within the latest mobile
    operating system. Hence, it is more intelligent technology, which will interconnect the
    entire world without limits. Likewise, our world would have universal and uninterrupted
    access to information, communication, and entertainment that will open a new dimension to
    our lives and will change our life style meaningfully.
    Moreover, governments and regulators can use this technology as an opportunity for the
    good governance and can create healthier environments, which will definitely encourage
    continuing investment in 5G, the next generation technology.
    How 5G provides continuous connection, greater
    capacity, faster speed and response time?
    BETTER CONNECTION - ALWAYS
    CONNECTED
    5G networks are designed to work in
    conjunction with 4G networks using a range of
    macro cells, small cells and dedicated in-
    building systems.  Small cells are mini base
    stations designed for very localised coverage
    typically from 10 metres to a few hundred
    metres providing in-fill for a larger macro
    network.  Small cells are essential for the 5G
    networks as the mmWave frequencies have a
    very short connection range.
    INCREASED SPECTRUM – GREATER CAPACITY, MORE USERS
    AND FASTER SPEED
    ■ In many countries the initial frequency bands for
    5G are below 6 GHz (in many cases in the 3.3-3.8
    GHz bands) and similar frequencies to existing
    mobile and Wi-Fi networks. Additional mobile
    spectrum above 6 GHz, including the 26-28 GHz
    bands often referred to as millimeter (mm) Wave,
    will provide significantly more capacity compared
    to the current mobile technologies. The additional
    spectrum and greater capacity will enable more
    users, more data and faster connections. It is also
    expected that there will be future reuse of existing
    low band spectrum for 5G as legacy networks
    decline in usage and to support future use cases. 
    ■ The increased spectrum in the mmWave band will
    provide localised coverage as they only operate
    over short distances. Future 5G deployments may
    use mmW frequencies in bands up to 86 GHz
    LOWER LATENCY – FASTER RESPONSE TIME

    Lower latency with 5G is achieved through significant advances in mobile device technology and
    mobile network architecture.
    ■ 5G Network - Mobile Network Architecture  Significant changes in both the Core Network (Core)
    and Radio Access Network (RAN) are required to deliver low latency.
    ■ Core Network Changes With the redesigned core network, signalling and distributed servers, a key
    feature is to move the content closer to the end user and to shorten the path between devices for
    critical applications.  Good examples are video on demand streaming services where it is possible to
    store a copy or ‘cache’ of popular content in local servers, so the time to access is quicker.
    ■ Radio Access Network Changes To achieve the low latency, the Radio Access Network (RAN) will
    need to be re-configured in a manner that is highly flexible and software configurable to support the
    very different characteristics of the types of services that the 5G system envisages.
    Low latency and high reliability over the air interface requires new radio techniques to minimise the
    time delays through the radio within a few TTIs.
    Limitations
    ■ 5G types of equipment are costly, requires skilled engineers to install and maintain a 5G
    network. This increases the cost of 5G deployment and maintenance phases
    ■ 5G technology is still under process and research is going on.
    ■ 5G smartphones are costly. Hence it will take time for the common man to make use of
    5G technology.
    ■ Security and privacy issue yet to be solved in 5G
    ■ Coverage distance of up to 2 meters (in indoor) and 300 meters (in outdoor) can be
    achieved due to higher losses at high frequencies (such as millimeter waves). 5G mm-
    wave may suffer many such losses (penetration loss, attenuation due to rain, foliage
    loss, etc.
    Challenges
    The primary challenges of present day cellular networks such as: higher data rates, excellent
    end-to-end performance, user-coverage in hot-spots and crowded areas with lower latency,
    energy consumption, and cost per information transfer are expected to be solved by the
    evolving 5G cellular wireless networks. By the existing definition, small cell backhaul
    connections are to be used to forward/receive the end-user (small cell user) information
    to/from the core network and to mitigate interferences. Energy efficiency scaling of
    antennas, backhaul load management, growth of variable data traffics and the trade-offs
    arising from these constraints producing large scope of promising future research in 5G
    technologies. These challenges have to be addressed.
    So, 5G systems will implement a multi-tier architecture comprising of macrocells, various
    types of licensed small cells, device-to-device(D2D) and relays networks to serve users
    with diverse quality-of service (QoS) requirements in a spectrum and in an energy-efficient
    manner.
    CONCLUSION
    5G technology is the upcoming technology and the bandwidth for this is
    very high and was having higher data transfer rate. However, now we are
    using the 3G technology efficiently and in some countries the people are
    using the 4G but in future we can use the 5G technology. Many big countries
    are investing huge amount of money on this project as it was having high
    demand in the future. It will altogether manufacture flexibility, limit, degree,
    comparability and meeting. Thus, it will satisfy the growing solicitations of
    rising bigdata, cloud, machine⁃to⁃machine, and diverse application.
