5G TECHNOLOGY

5G TECHNOLOGY

Mobile technology has revolutionized communication. Wireless technology has improved from 1G to 4G. Mobile usage is on the rise. Over 100 million mobile phones are currently used in India. Improved communication is the natural needs of people. 4G is just getting started. The fastest communication system is being explored and 5th generation, 5G wireless mobile technology is under study. It takes many years for a new cellular system to be introduced. 5G technology must be selected, developed and launched.

    The spectrum that the service operator has purchased with prices from the government is almost over. The spectrum must meet demand. The user will have to send more bits through the spectrum now available by looking for new spectrum or developing new technology.

  4G mobile did not launch well though. The operator, mobile maker and leading research firm has begun research to develop 5G mobile technology, which will be launched in 2020 on a business basis. In 5G all objects and every human being will be interconnected.

  1st generation Mobile 1G to 5G evolution is as follows.

  The 1st generation, 1G was analog.

    There are 2nd generation, 2G GSM (Global System for Mobile) and CDMA (Code Division Multiple Access). It can send SMS. Limited data can be sent and talked from 9.6 kbps to 19.2 kbps. 2G range 800/900 MHz or 1800/1900 MHz, Bandwidth 30-200KHz.

   2.5G launched between 2G and 3G. 2.5G (GPRS) speed 56 Kbps. GPRS (General Pocket Radio Service) EDGE followed by GPRS. EDGE speeds are 236.8 Kbps, slightly higher than GPRS. Evolved from EDGE to 3G.

   3rd generation, 3G reads WCDMA, HSPA. 3G launched in 2001. Mobile internet is available on 3G. Speed ​​from 384Mbps to 2Mbps, bandwidth 1.6MHz – 2.5MHz Speaking of which, video calling can be done. Files can be sent, internet can be surfing. Video chatting can be done. However, its speed is low. There are many types of 3G.

   Also called 4th generation, 4G mobile, 4G LTE (4G Long Term Evolution). It is all IP based technology. Its frequency band is 12.8 GHz, bandwidth 5-20Mhz, data rate or speed 20Mbps. Its switching-packet, Access-MC-CDMA or OFDM. Together voice, video can serve data. 10 times the speed of 3G. Seamless video can be streaming, HD mobile TV is available, HD video can be seen, it can be downloaded instantly. 4G mobile has not started yet. It was expected that 4G would be faster. Many technologies are called 4G and are implemented in different ways. But people say 4G is not too fast.

  Demand for wireless data will continue to grow.

   5th generation, 5G is the next step in the evolution of mobile communication. Its speed will be faster, the ability to connect a large number of devices. Nearly a billion sensor, actuator, and similar devices can be deployed and the devices can communicate with each other. Their demand is very low, and together they will not affect the traffic volume. 5G movie can be downloaded in 1 second, data rate will be higher for many users in cell together. 5G details are being discussed.

    What is 5G: - 5G (5th generation mobile networks or 5th generation wireless systems)

    5G is the next standard of 4G in mobile communication evolution. 5G Infinite data can be accessed and data can be sent to any person and any object, anywhere and anytime. Not only will 5G give people mobile connection, 5G will give connection to all kinds of new applications, any kind of omnibox device, application, wearable, smart home, traffic safety / control, industry application etc. and send and send media at high speed. This is not a specific radio-access technology when compared to other genaration. It will meet the need for overall wireless mobile communication. It will be faster.

    5G Requirements and Capabilities: - 5G i) Massive system capacity, ii) Very high data rate everywhere, iii) Very low latency, iv) Ultra high reliabity and availability, vi) Device price is very low and low energy and cost low and v) network energy costs will be lower. In 5G all objects and every human being will be interconnected, all united (forming a united whole). It is estimated that by 2020, there will be 50 billion devices on mobiles all over the world, which will be anything but earthly, with thousands of objects. Each person will be permanently connected to their doctor, friend, colleague, client / supplier, security service, and more, their car, fridge, bekary, metro, airport, house, etc. 1 robot can operate, surgeon will control the robot from the other end of the earth. This band requires high bandwidth and low latency above 4G for this to work. One has been told that speed will be 1-10 Gbps (not theoretical), giving thousands of sensors with one connection. The spectral efficiency will be much higher than 4G. Coverage and signaling efficiency will be improved, 1 millsecond latency, 1000x bandwidth in single area, 10-100x no connection device, 99.999% availability, 90% coverage, battery life up to 10 years and energy consumption on network up to 90% less. Will be In current technology, increasing the nework capacity by 1000 times the energy cost will be so high that it is not possible to provide. 5G is supposed to work at 10% energy. 5G target 10 Gbps speed. The success of these 5Gs will be achieved through technology. It was not decided which technology would be used. Some evolutionery technologies are discussed below. One more important thing
