Isro's new communication satellites to usher in high-speed internet era

NEW DELHI: Indian Space Research Organisation (Isro) is planning to usher in an age of high-speed internet connectivity in the country with the launch of heavy-duty communication satellites.

Giving details about the upcoming launches this year, Isro chairman Dr K Sivan toldTOI: “We will launch Gsat-11 in April or May.” The 5,725-kg satellite, which will carry 40 transponders in the Ku-band and Ka-band frequencies, is capable of “providing high bandwidth connectivity” with up to 14 gigabit per second (Gbps) data transfer speed.

“We will launch Gsat-11 from the European spaceport as it’s a five-tonne satellite. Around the same time in May, Isro will launch Gsat-29 through our GSLV Mk III rocket from Sriharikota. Thereafter, we plan to launch Gsat-20 from India itselfby next year,” the Isro chief said. Last year on June 5, the Indian space agency had launched Gsat-19, which too carried Ka/Ku-band high throughput communication transponders.

Dr Sivan said, “Together, all these satellites will provide high bandwidth connectivity of up to 100 gigabit per second. They will provide high-speed internet connectivity in rural areas as well and help bridge the digital divide.”

When it comes to mobile internet speed, India ranked a disheartening 109 out of 122 countries, says popular speed testing service Ookla in its 2017 November edition of Speedtest Global Index. However, India stood at a little better 76th rank out of 133 countries in broadband speed, says the report.

According to the index, average mobile (download) speed in the country last November was 8.8 Mbps. Norway was the fastest mobile network with an average speed of 62.6 Mbps, followed by Netherlands with 53 Mbps, Iceland (52.7 Mbps) and Singapore (51.5 Mbps). India also fared poorly when compared with its neighbours. According to the November index, China ranked 31st and had a speed of 31 Mbps, Pakistan with 13 Mbps was ranked 89th even after slipping three positions, Nepal (99th rank) had 10.9 Mbps and Sri Lanka (107th) had 9.3 Mbps download speed.

When it comes to broadband speed, India stood at 18.8 Mbps. Singapore led the way with 153.8 Mbps, followed by Iceland with 147.5 Mbps and Hong Kong (133.9 Mbps). China ranked 23rd with 61.2 Mbps, Sri Lanka had 19.2 Mbps and Pakistan on 126th spot with 6 Mbps. Though India needs to go a long way in boosting internet speed, Isro’s new satellites are expected to be a game-changer for the country.
