What are the advantages in using radio waves for communication over interstellar distances?

Answer 1

The various advantages of microwave communications are as follows:

1>large bandwidth availability

2>less power requirement with the use of repeaters

3>easily penetrable to the areas like even the ionosphere

4>line of sight propagation

5>reduces the size of the antenna

6>can accommodate more number of channels

Answer 2

Radio waves reach the ground which means that they can be viewed from the ground and you don't have to travel up into space to view them. They also can observe phenomena's that other wavelength ranges cannot view.

Answer 3

There are several reasons. Here are a few:

-- We know how to modulate them ... add information onto the radio waves that we send,

and gather the information off of the radio waves that we receive.

-- We know how to generate radio waves, and transmit them with tremedous power.

-- We know how to use giant dish antennas to focus the tansmissions of radio waves

into a tiny cone, with the effective isotropic power of millions of watts.

-- We know how to use the same antennas to gather microscopic 'nano'-samples

of incoming radio waves.

-- We know how to use electronic circuits to recover information from incredibly tiny

samples of radio waves ... as little as -150 dBm (0.000000000000000001 watt ! ).

-- We're not able to do these things with waves at substantially different frequencies.

-- The Earth's atmosphere is reasonably transparent to radio waves, so we don't

lose a lot of the energy in them as they pass in or out through it.

Answer 4

The advantages in using radio waves are;

• it works fast
• help us to communicate more faster
• helps us to connect our family from far distance or in other countries
• increase leck of knowledge

DIDN'T DO MY RESEARCH BUT THIS CAME FROM MY MIND BY TYPING TALKING TO MY COUSIN AT THE SAME TIME

GOTTA LOVE SCIENCE :P
