Imagine getting email and data over the radio. A
22-year-old has developed a software that lets one do just that. Radio
reaches every corner of India. Small transistors are cheap and easily
available. Vinny Lohan has found a way to send computer data over normal
radio waves. He believes that the idea could get all India online in a
jiffy.
"Computers are all about zeros and
ones. Be it video or text or music, to a computer, it is all zeros and
ones. Since that's so, we asked ourselves, can we take a book or a video
and convert it into music. And then send it over the airwaves. Turns
out the answer was yes," Vinny said.
All it
needs is OneBeep, the special software that Vinny and his friends wrote
together. To send a file, be it video or text, the broadcaster simply
selects and drags it into the software. OneBeep converts that data into
an audio file, which is then transmitted over the airwaves.
Listeners
can plug in their radio to a laptop or a cheap tablet computer, using a
normal headphone jack. OneBeep software installed on their machines,
will automatically convert the audio files back into data. It's like
getting email over the radio.
OneBeep CEO
Vinny says, "It's a bit like bit-torrent. When you are downloading
something, the software is intelligent enough to know when something is
paused and when it is restarted. We break digital data into packets. The
software is converting audio into packets of data on the computer. Say
your signal is weak or your battery died. When it restarts, it starts
from the place it left off."
OneBeep needs
absolutely no changes to the existing radio stations. And so, it's got
attention. In 2010, Vinny and his team bagged the third prize in
Microsoft's Imagine Cup - a worldwide contest for tech innovators. But
their idea does have a few drawbacks.
First
off, it's slow. Sending just 2 MB of data can take upto 40 minutes.
Second, the idea itself isn't new. HAM radio operators have used a
somewhat similar software since the 1970's. Third, it could be misused
by terrorists. But Vinny thinks he's got that base covered.
"Each
radio frequency transmission needs a government licence. Most amateur
transmitters have a range of 20-30 metres. Anything stronger than that
can easily be traced. If any unauthorised frequency transmissions take
place, the army will be privy to that," Vinny says.
But
because it's so simple and easily adaptable, Vinny's idea still has
potential. Rural school kids can use OneBeep to download assignments
overnight. Community radio stations in villages can also use it to
transfer panchayat related files.
India will
soon adopt Digital Radio Mondiale, a new technology which besides great
sound, offers file transfers on the radio. But that is still a few years
away. OneBeep already works and Vinny wants to offer it for free on the
web. He wants to kick off a tiny revolution and give rural India a
taste of the internet over the radio.
