    5G TECHNOLOGY | ITS BAD IMPACT UPON US:

     5G Technology and its bad Impact upon Us:

    From the ancient time man is looking for how to get an easy, comfortable and lazy life without doing too much work everything can be done easily. With this aspiration of man the World is standing in such a position that anything can be done with the help of Technology. But it’s also true that too much greed may lead us to a condition from where we can’t get back or impossible to get back. Here I am talking about the 5G Technology, the fastest wireless technology in the World.
    Expected Date:
    This 5G Technology may appear in our daily life by 2020 as expected by the Inventors. No doubt this is a good effort of our scientists or technologists who are fully involved in this project. We welcome their effort of making such a technology.

     Advantage of 5G Technology:

    This kind of wireless technology i.e 5G Technology will give us too much internet speed about 1.4 Gbps by which we will able to watch direct broadcast of football, cricket, Olympic and many others programme. Not only that but it will also connect many dev ices (which is called IOT). The problems facing by the manufacturer of self driving car will most probably be solved as the present 4G internet connection is not enough for this kind of technology. The self driving car requires flawless stable and high speed internet connection. 5G internet connection will help providing such connection to the self driving cars.
    It will also help us in medical field. Suppose, a critical operation needs some experts help or instruction and the doctors are away from there, 5G Technology or Internet connection will help us to come out from this kind of dangerous situation where a life is in critical condition. It will be possible for its least latency and high speed which the present 4G connection fails to give.
    2.In Automation industries:
    Automation industries will be improved day by day with the help of 5G Technology. The labor cost will be cut down and we will use their things in low cost. It sounds good for us.
     
    5g-technology-its-bad-impact-upon-us
    5G TECHNOLOGY AND ITS BAD IMPACT UPON US

    Bad Impact upon Us:

    But, can we realize the bad impact of it upon us as well as upon the whole living beings? The answer is probably no. Because we are dancing around , thinking that we will get very very fast Internet connection in our cell phone, laptop or computer which will help us playing 4k online games, watching movie, match etc.
    Can we know what we have to pay for it? Let’s have a small discussion that I realize. To give us such stable connection by using 5G technology, too much towers are required around us as it uses millimeter wave length which has less penetration strength or capabilities in comparison with 4G Technology. Its signals will come to the devices in beam form with small cell technology which the 4G or 3G already uses.
    Too much towers mean too much radiation as we already know that every electronic device that is connected to the internet gives out radiation. The more implementation of IOT will give out more radiation. The radiation that the 5G Technology gives out may have extremely bad impact in our life. Instead welcoming this kind of technology we should think of its danger. The Eco system will also be affected gradually for the radiation. So, be careful and cautious before using such kind of technology.
    Conclusion:
    We can’t ignore the Scientists or the Technologists who are making this will have too much responsibility towards us. They are also thinking a lot about the bad impact of it. They should be more and more careful and cautious before implementation.

    5G TECHNOLOGY | 5G INTERNET

    5G Technology and 5G Internet:

    Who doesn’t love speedy internet? The answer is simply “Yes”. Therefore, there is no surprise that every major telecom operator in the world is working to make it faster and even faster. Cell Phones (Especially Smart Phones), watches, homes, and cars are increasing rapidly requiring stable internet connections. In order to overcome this we need a powerful wireless signal. To solve our problem of slow internet connection 5G is knocking at the door. 5G is a wireless connection built to give a better and stable connection to the devices that need it. It is similar to 4G and 3G that was introduced before but the major difference is its frequency. It’s not that only your phone and your PC or Laptop but many home appliances, door locks, security cameras, cars and many other devices will also be connected to the internet with the help of 5G. By 2020 it is expected that 20.8 billion devices will be connected to the internet. Now, approximately 6.4 billion devices are connected to the internet using 4G connection and it is connected to the world also. So, in future a lot more IOT (Internet of Things) will be connected to the web. According to the technologist 5G is the future wireless technology of the world. It will make our life more and more comfortable. The use of self driving car will have some breath for this technology.

    5G Technology & Internet

    What is 5G technology?
    Here the “G” in 5G stands for “Generation” that means 5th Generation Wireless phone technology which was technically started with 1G and generation after generation it is increasing as 2G, 3G and now 4G that is the latest one with LTE (Long Term Evolution) technology. 5G is inspired by this kind of LTE technology. It will give us more and better speed that will enable us to watch 4k video and Games using 5G internet as there will be a little bit of latency. In medical emergency doctor can take the help of this technology with which our precious life can be saved.5G wireless technology will work in 28Ghz frequency for which the wave length will be the shorter than that of 4G or 3G. As the frequency is enormous the wave length is technically lesser (It will be in millimeter) and for this there will be a drawback. The penetration capability will be lower than that of the previous 4G or 3G.But it will be overcome with the help of implementation of more tower and using more antenna in mobile phones. The research is going on rapidly to make it materialized as soon as possible.

    5G technology in India
    India is not lagging behind the other developed countries. India is also set up a panel constituted by three Secretaries of the Department of Telecom, IT and Science and Technology by the Department of Telecommunication (DoT) in view of introducing 5G by the year 2020. JIO Telecommunication is also trying to implement it with the collaboration of Samsung which is already invented a 5G modem which will give us 6GZh frequency as per company and it is in a testing position. If everything goes well India will also launched 5G wireless network very soon.
    5G launched dates:
    There is no prediction yet by the Government or any other telecom operator; but it is expected that 5G will sure be launched in India by the year 2020. United State is already making some trial around some places like Texas, Oregon, and New Jersey.

    Last but not least 5G internets will give us a better internet experience and will make our life easier.

    ARTIFICIAL INTELLIGENCE:

    Artificial Intelligence:

    Artificial Intelligence is the future technology of the World. It is briefly called AI. Almost all the country in the World is running after it. But there is too much controversy among the Scientist regarding this kind of technology. Some of them questions that this technology will destroy the human race as well as the World; but some opines that it will help developing us by providing many things like labour, security, privacy etc.
    Now, the question arises that what is Artificial Intelligence. It is in brief a kind of machines learning. A kind of programme that is implemented on variety of machines and act like that. If the programme is programmed to act like human beings, it work exactly like this. The programme works after gaining knowledge from human beings and automatically implemented it. How can it gain knowledge? It gains knowledge after properly observing human's behavior, gesture, smile, quality of speaking etc. If the programme is going to be implemented on a kind of machines which can act other works. It can then be programmed like that. All what the machines learns store them in its memory and act accordingly from its past knowledge or experiences.
    Artificial Intelligence

    Artificial Intelligence

    Here is a small example. We use smart phone and some smart phone has finger print unlocking or face unlocking feature. The phone uses AI. It has the power of face recognition . This power can unlock your phone because at the time of configuring your smart phone it recognizes only your face. So, only you can unlock it. It is really a good feature for our security and privacy.
    There is some reports revealed in some International Newspaper that The University of Southern California has made an experiment among 134 couple and came to the conclusion that Artificial Intelligence can can tell us the relationship between the couple and how much time their relationship will long last. It works only by observing their gesture, the voice and time of their talking to each other. The Intelligent machine will then tell us what is going to be happened among the couple. Is it not interesting? 
    Sofia, the first robotic girl, can perform a lot of duties properly without making a little bit of mistake with the help of AI. It is really a great invention of the modern World. It should be known to us that Sofia is now the citizen of Soudi Arabia and it is now the most controversial topic among the critic and the scientists. To them it will make a critical situation for human beings if it behaves otherwise or trained to act like devil.
    Sir Stephen Howking properly said:- " The development of full artificial intelligence could spell the end of the human race".
