Why in the News?
Reliance Jio has successfully demonstrated JioSpaceFiber at the India Mobile Congress.
What is JioSpaceFiber?
JioSpaceFiber is India’s first satellite-based gigabit internet service.
It uses medium earth orbit (MEO) satellite technology to provide high-speed internet access to remote and underserved areas.
Partnered with: Jio has partnered with SES to access the world’s latest medium earth orbit (MEO) satellite technology.
How is JioSpaceFiber different from Starlink?
Orbit: JioSpace Fiber uses medium Earth orbit (MEO) satellites while Starlink uses low Earth orbit (LEO) satellites.
– MEO satellites orbiting at a greater distance from the planet will have higher latency (latency is the time that data takes to transfer across the network) than LEO satellites.However, MEO satellites can cover larger areas with fewer satellites.
Availability: JioSpaceFiber is currently only available in India while Starlink is available in over 30 countries.
What is Satellite Internet?
| Aspect | Description |
| Technology | Utilizes communication satellites in orbit around the Earth to provide internet connectivity to users |
| Working | (1) Internet service providers send an internet signal to a satellite in space which then comes back to the users and is captured by their satellite dish. (2) The dish is connected to the user’s modem, which finally connects their computer to the internet signal.This process then reverses back to the internet service provider and is repeated every time. |
| Advantages | Accessibility of internet in remote regions, quick deployment, potential alternative when other internet options are limited |
| Disadvantages | Higher latency, potential for service interruptions due to weather and usually higher costs |
