Reliance Jio recently declared that it had effectively tested the first gigabit internet service in India, based on satellite technology.

Facts About:

  • Satellite Internet operates in a way similar to satellite TV.
  • It begins with an internet service provider launching satellites into space to orbit the Earth.

                 These satellites, placed in low- or high-Earth orbit, transmit a signal.

  • A receiver dish, positioned in your home or business, captures this signal.

                 It should have an unobstructed view of the sky.

  • You connect a modem to this dish to convert the received signal into usable internet connectivity.
  • High-speed satellite internet is typically delivered through constellations of low-Earth orbit (LEO) satellites.
  • LEO satellites orbit the planet at altitudes ranging from 250 to 2,000 kilometers.
  • Communication between these satellites and Earth occurs using radio waves.

Advantages of Satellite Internet:

  • Satellite Internet is ideal for users residing in rural or remote areas, far from urban centers or cable/phone offices.
  • It relies on a satellite dish for two-way communication and doesn't require telephone cables or lines.
  • When compared to other internet options, satellite internet experiences fewer or minimal network outages.
