I'm wondering what are the thoughts of respected ladies and gentlemen
on the topic of mobile streaming?
Let's take a look at the facts: 3G/UMTS cell phone network is here.
Mobile phones are steadily penetrating the market. Current technology
in use provides data throughoutput of 384 kbps. With current codecs
like aacPlus, this can be used for either high-bitrate streaming for
transparent (CD-quality) audio streaming, or low bitrate, low cost,
"entertainment" quality streaming. The HSDPA upgrade for 3G network
that is going commercial now, raises the bitrate bar to 1.8 Mbps. The
final data throughoutput will certainly reach 14Mbps, and possibly
over 20Mbps. Good enough for _any_ kind of streaming ;-)
GSM network is fairly robust, in mobile environment as well. I'm
talking cities here, that have sufficient number of base stations
providing coverage. As far as cost goes, some mobile operators are
going flat rate from the start (T-mobile in Great Britain, for
example). At one point in the future the service will certainly be
flat rate, even if it isn't right now.
So I'm wondering if this will be a viable alternative to IBOC?
Last week I had an opportunity to play with MDA Vario (Qtek 9000)
PocketPC/cell phone hybrid. It's not 3G/UMTS enabled, but supports
EDGE and GPRS. I installed an aacPlus player and connected to one of
the streams I'm running on Radio Student
(http://radiostudent.redirectme.net). I drove around town listening
to the stream without a single dropout or re-buffering. Later I
connected to one of the Boomer radio streams from Tuner2.com portal
and enjoyed soul classics from distant Florida while driving around
Zagreb, also without a single dropout :-) Bottom line is - this
works! Even on EDGE enhanced-network, let alone 3G/UMTS or HSDPA.
Mostly all mobile phones today have Bluetooth connectivity. But more
importantly, better car radios come with Bluetooth as well so you
could talk hands-free in your car. And it works very plug-n-play. You
don't even have to do anything. The radio automatically recognizes
your mobile phone and interrupts what you're listening when a calls
come in, which is then routed to car's audio system. You talk while
your mobile phone stays in your pocket. There's no reason why a
Bluetooth connection couldn't be used for playing audio from your
mobile phone. Either audio from phone's internal memory... OR
streamed live from the network. When you go to your office, you can
connect your phone to your small table-top radio or big sound system
via Bluetooth as well.
So for a fixed monthly cost, only slightly higher than what you are
already paying your mobile service provider, you can listen to any
station, anywhere in the world, anywhere you happen to be on the cell
phone you are already carrying with you all the time. And, unlike
IBOCs 96kbps, 48bps, 32kbps (or even lower than that), this could
easily and soon be in true, 44.1kHz, 16 bit, linear, stereo digital quality!
I don't know, but it looks to me IBOC is about to face some pretty
advantageous and easy-to-use competition. The future of radio might
very well lie in delivery through mobile networks...
