The question is impossible to answer, because it rests on a false hypothesis.
Radio is the only possible way to pass information to and from artificial satellites.

Do satellites normally use microwaves or radio waves?
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
Communications occur over what such as telephone lines cables cellular radio networks and satellites?
operating systems
Can xm satellite radio be used in Bahrain?
It will only work online. Their satellites don't reach out in that area.
Can a satellite radio get gps signal?
No. The satellites used to distribute Sirius/XM "satellite" radio operate on frequencies assigned to Sirius/XM "satellite" radio. They don't operate on frequencies allocated to the GPS system.
What inventions were influenced by the radio?
The radio is believed to have been invented by Guglielmo Marconi but recent debates have proved that it was Nikola Tesla who first demonstrated the device. Some inventions that were influenced by the radio were the remote control, television and satellites.
Examples of artificial satellites?
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
What are natural and artificial satellites?
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
What is artificial satellites and roll?
Artificial satellites are man-made objects that have been launched into space to orbit a planet, usually the Earth. Their roles depend on what they've been built for. The GPS satellites provide positioning information so that GPS receivers on Earth can know where they are. Weather satellites tracks clouds and storms. Communications satellites transmit TV, radio, phone calls and data, and so on.
How do satellites pass information to people on the ground?
By means of radio communication.
How does the weather information from satellites get back to earth?
In very much the same way as it gets to your radio, your TV, or your smartphone ... by radio signals.
Do satellites normally use microwaves or radio waves?

How do satellite dishes help us?
They help us communicate with the (artificial) satellites. We can receive tv and radio programs from them, we can bounce telephone and data communication off them and so on.
Mention any one method of communication which is used by government to disseminate information at various levels during disaster?
satellites, ham radio, television,radio etc....
What parts of the spectrum other than visible light are important to astronomers?
There's information to be learned from every part of the spectrum. That's why we build radio telescopes on Earth, and outfit artificial satellites with instruments to observe the parts of the spectrum that don't penetrate the atmosphere, like X-rays.
Give some reasons why artificial satellites are launched?
Satellites are used for a great many things. Communications satellites beam TV, radio, and telephone signals all around the world. Navigational satellites help people know where they are and get where they are going. Weather satellites take pictures of clouds and storms from above to help make weather forecasts. Spy satellites look down and snoop on other countries. Other satellites help scientists to study Earth and other planets
