India to Enter 70 Gb/s High Speed Internet Era with ISRO''s New Satellites Launch



Despite India overtaking the U S last year to become the world's second largest internet user base after China, India is still behind many Asian countries when it comes to internet speed.



But things are set to change in the next 18 months when Indian Space Research Organisation (ISRO) plans to start an age of high-speed internet in the country with the launch of three communication satellites.



Isro will launch three communication satellites. the GSAT-19 satellite will be launch in June this year and then GSAT-11 satellite and at the last GSAT 20 satellite.



These satellites will use multiple spot beams (a special kind of transponder that operates on a high frequency) that will increase internet speed and connectivity. These multiple spot beams will cover the entire country." A spot beam is a satellite signal that is specially concentrated (sent by a high-gain antenna located on the satellite) so that it covers only a limited geographic area on earth.



The narrower the beam, more is the power. The three satellites will reuse "beams" (signals) several times over smaller areas. In contrast, traditional satellite technology uses a broad single beam to cover wide regions.



These new satellites, once operational, will be capable of providing high-quality internet, phone and video services." the effective data rate of earlier-launched GSAT satellites is one gigabyte per second.



GSAT-19, on the other hand, will be able to transfer data at four gigabytes per second, thus making it equivalent to four satellites. " GSAT 11 is One of the heaviest satellites ever to be built by ISRO, will be launched by the year end. It will be able to transfer data at the rate of 14 gigabytes per second. GSAT-20, whose launch is set at the end of 2018.



This satellite will have data rate of 60-70 gigabytes per second. The GSAT 19 satellite will use eight beams, while GSAT 11 satellite will use 16 beams and GSAT 20 satellite will use 40 beams.



Each beam will have two polarisations, which will effectively make them 80 beams.



The number of internet users in India is expected to reach 450-465 million by June 2017, around 4 to 8% increase from 432 million in December 2016, according to a report from the Internet and Mobile Association of India.



The India with just 4.1 Mb per second average connection speed, ranked a poor 105th on the world's fastest internet connectivity speed list.



India is way behind than South Korea which is on first position with 26.3 Mb per second internet speed and Hong Kong have 20 Mb per second internet speed, Sri Lanka have 6 Mb per second internet speed, Vietnam have 6.3 Mb per second internet speed and China have 5.7 Mb per second internet speed. but The launch of these three satellites will be the game-changer for India.
