When Will FM Radio Analog Technology Switch To Digital?

FM radio is one technology which became a part of our lives very long ago. It is used widely in all the regions of the world. It is obvious that each region will have different frequency modulation but the core idea of its operations remains the same everywhere. However, it is unfortunate to highlight that despite various technology sophistications, radio has been neglected. Today we have moved from analog to digital broadcasting in television. So the question arises that why has radio not experienced better technology?

The answer lies in the fact that we use radio spectrum for digital video broadcasting in television. These radio frequency spectra are used to transmit digital multiplex, which is a bundle of various television channels and other services by using 6-8 MHZ of bandwidth. Obviously, in terms of usage, digital broadcasting in television is making more efficient use of radio frequency spectrum as compared to analog broadcasting, which used the same bandwidth to broadcast only one program. This justifies the change in technology. At this important to mention that radio technology can be moved from analog to digital but it will take years to switch and grand scale technological preparations to make it happen.

It is important to mention that switching from one technology to other does not only take time but also consistent efforts to analyze each aspect of the newer technology. Mainly factors like good sound quality, excellent reception of signals and more efficient use of radio spectrum by increasing the capacity; are given the top priority. There have been many inventions which have resulted in digital broadcasting of sound like T-DAB, DRM+, DVB-T, DRM and DVB-T2, which certainly have good reception and output; but none of these have been impressive enough so that it can replace analog radio transmission.

FM radio employs 250 kHz bandwidth with spacing of 100 and 200 kHz, varying as per the region. It is because of this changed combination of bandwidth and spacing that switching from analog to digital in radio broadcasting would be difficult. Hence, we have to remain contented with the analog radio transmission unless the sophistication of the technology rises!

In the end, it is significant to mention that up-gradation in scientific technology is not a matter of a few months or decisions of a small organization. Rather, many years efforts, time investment, financial investment and consistent dedication are required for a technology to switch from its current level to a higher level. Sophistication in technology is highly desired by all in various fields, because it not only results in provides comfort to the users but also becomes a source of pride to the inventors. The same is the case in upgrading radio technology but the other factors which are currently making the switch from analog to digital technology can also not be neglected.
