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

It hasn't been done and there is a problem because the background noise would prevent the use of radio communication over more than about 1 light year's distance. Radio waves travel at the speed of light, so it would take 2 years to get a message there and back from 1 light-year away.

How can you see through the interstellar medium?
by observing in high-energy wavelengths such as X rays and long wavelengths of light such as radio waves
This layer is responsible for the possibility of radio communication?
The Ionosphere
Modes of communication with outer space?
Radio is the only way we have of communicating with astronauts or machines in space.
What are alternative communication system during disaster?
Some alternative communication systems during a disaster include two-way radios, satellite phones, and hand signals. These allow rescuers to quickly coordinate their efforts and find victims.
How do scientists use magnets?
Telephone, television, radio, and internet all use magnets to aid the communication.
Advantages and disadvantages of communication satellites?
advantages and disadvantages of broadcasting radio ?
Why were early radios called wireless?
Up until the invention of radio, communication had to be sent long distances along wires and cables. i.e. telegraph or telephone. With the invention of radio, communication was not restricted to the use of wires. Hence wireless is two words 'wire' and 'less' meaning without wire.
Radio waves of 21cm wavelength originate from which component of the interstellar medium?
Cold atomic hydrogen
What is advantages and disadvantages of cellular radio?
One advantage of a two-way radio is the fact that they can connect to each other over long distances. A disadvantage is the fact that other people on the same channel can listen to the conversation.
What is the use of radio communication?
it is used for the communication
What characteristic of radio waves makes them useful for determining the shape of a galaxy?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed

What characteristics of radio waves makes them useful for determining the shape of a galaxy?

The frequency of a light wave with wavelength 0.005 meters is Hz?
Frequency = speed/wavelength = (300,000,000)/(0.005) = 60 GHz.This is not light. This is microwave radio communication over relatively short distances.
What are the disadvantages of local radio?
Banana!
Why do we use radio?
Communications over long distances are economically achieved by the utilization of radio waves.
How wireless communication developed?
Communication over wires is a relatively recent innovation and started with the telephone/telegraph - even radio communication involves use of wires in the radio sets and ariels. Before using the telegraph people used to write letters to each other and post them. People also spoke to each other face to face or "yodeled" across valleys in the Alps. When wanting to communicate over longer distances the American Indian people used smoke signals, the English used fire beacons and semaphore flags. People also used mirrors and shuttered lamps to communicate over distances. All this is wireless communication.
