    Before You Read 
    What are advantages and disadvantages of 
    Wireless Networking (Wi-Fi)? 
    What do you know about 5G Technology?

    Read the Article 
     
    5G Technology 
    Radio technologies have evidenced a rapid and multidirectional 
    evolution with the launch of the analogue cellular systems in 
    1980s. Thereafter, digital wireless communication systems are 
    consistently on a mission to fulfil the growing need of human 
    beings (1G…4G, or now 5G).
    The Fifth Generation technology has many salient features potential enough to solve many of the 
    problems of our mundane life. In comparison to previous radio technologies, 5G has following 
    advancement − practically possible to avail the super speed i.e. 1 to 10 Gbps; latency will be 1 
    millisecond (end-to-end round trip); 1,000x bandwidth per unit area; feasibility to connect 10 to 
    100 number of devices; worldwide coverage; about 90% reduction in network energy usage; 
    battery life will be much longer; whole world will be in Wi-Fi zone. As researchers say, with the 
    wide range of bandwidth radio channels, the 5G Wi-Fi technology will offer contiguous and 
    consistent coverage − “wider area mobility in true sense.” 
    Architecture of 5G is highly advanced, its network elements and various terminals are 
    characteristically upgraded to afford a new situation. Likewise, service providers can implement 
    the advance technology to adopt the value-added services easily. 
    However, upgradeability is based upon cognitive radio technology that includes various significant 
    features such as ability of devices to identify their geographical location as well as weather, 
    temperature, etc. Cognitive radio technology acts as a transceiver (beam) that perceptively can 
    catch and respond radio signals in its operating environment. Further, it promptly distinguishes the 
    changes in its environment and hence respond accordingly to provide uninterrupted quality service. 
    The system model of 5G is entirely IP based model designed for the wireless and mobile networks. 
    The system comprising of a main user terminal and then a number of independent and autonomous 
    radio access technologies. Each of the radio technologies is considered as the IP link for the 
    outside internet world. The IP technology is designed exclusively to ensure sufficient control data 
    for appropriate routing of IP packets related to a certain application connections, i.e. sessions 
    between client applications and servers somewhere on the Internet. Moreover, to make accessible 
    routing of packets should be fixed in accordance with the given policies of the user. 
    The 5G MasterCore is convergence point for the other technologies, which have their own impact 
    on existing wireless network. Interestingly, its design facilitates MasterCore to get operated into 
    parallel multimode including all IP network mode and 5G network mode. In this mode, it controls 
    all network technologies of RAN and Different Access Networks (DAT). Since, the technology is 
    compatible and manages all the new deployments (based on 5G), it is more efficient, less 
    complicated, and more powerful. 


    30 
    Surprisingly, any service mode can be opened under 5G New Deployment Mode as World 
    Combination Service Mode (WCSM). WCSM is a wonderful feature of this technology; for 
    example, if a professor writes on the white board in a country – it can be displayed on another 
    white board in any other part of the world besides conversation and video. Further, new services 
    can be easily added through parallel multimode service. 
    The 5
    th 
    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. 
    5G is the forthcoming revolution of mobile technology. The features and its usability are much 
    beyond the expectation of a normal human being. With its ultra-high speed, it is potential enough to 
    change the meaning of a cell phone usability. 
    With a huge array of innovative features, now your smart phone would be more parallel to the 
    laptop. You can use broadband internet connection; other significant features that fascinate people 
    are more gaming options, wider multimedia options, connectivity everywhere, zero latency, faster 
    response time, and high quality sound and HD video can be transferred on other cell phone without 
    compromising with the quality of audio and video. 
    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. 
    Normally, it is expected that the time period required for the 5G technology development and its 
    implementation is about two years more from now (by 2020). But to becoming usable for the 
    common people in developing countries, it could be even more.
