Conclusion :

Since many  years, voice and data radio transmission are increasingly powerful and are  continually changing.

The advance of digital transmission systems has enabled the invention of new telecommunication technologies
for wireless transmission whose performance  (speed and security) has been increasing.

The radio is  part of our daily lives, we use it every day, either to make a GSM call or  simply listen to music,
but do you think that all these waves that are around  us continuously can be dangerous for our health?

Do you think that,  in a few years, there could be an “after digital” in radio transmission?
