In 90s era very few people in India had access to internet and those who had, could seen hooked up on their telephone operating dial-up internet connection having bandwidth speed of few Kbps and then came Internet revolution where companies like Airtel, Hathway, Tata and BSNL started offering comfortable speed to users in India.
In 2016, it was nothing less then a bonanza when Airtel introduced 100 Mbps internet plan then in last year, an ISP made a milestone by introducing India’s first 1 Gbps wired broadband internet connection but those too are past now as the speed has now become unmatchable for ever growing internet users in India. India has the world’s second largest internet user base yet the country’s rank in broadband speed is 76th in the world.
Now in a latest development, chairman of Indian Space Research Organisation (ISRO), has said that India will soon enjoy more than 100 Gbps high bandwidth connectivity across the country in the next few years with the launch of three GSAT satellites before the end of next year.
As ISRO will launch GSAT-11 and GSAT-29 by end of this year and GSAT-20 will be launched by early next year. Notably, these three satellites are high throughput satellites and together they will provide more than 100 Gbps high bandwidth connectivity across the entire country which will help bridge the digital divide, said Dr K Sivan, chairman of ISRO, at an event.
GSAT-11 and GSAT-20 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. These new satellites, once operational, will be capable of providing high-quality internet, phone and video services
GSAT-11, which is heavier than GSAT-19, will be launched by the year-end and will use 16 beams. It will be able to transfer data at the rate of 13 gigabytes per second. GSAT-20, whose launch is set at the end of 2018, will use 40 beams. Each beam will have two polarisations, which will effectively make them 80 beams. So, GSAT-11 satellite will alone have data rate of 60-70 gigabytes/sec.
Few days back have reported about the same set of communication satellites which will also be a boon for rural Indian population to get high-speed bandwidth connectivity.
