How mobile technology is keeping the BBC Olympic Torch coverage on the air

Mark Bridge writes:

A horse box and eight SIM cards. That’s the basic technology keeping the BBC’s Olympic Torch Relay broadcasts on the air and on the road.

Cameras on BBC Olympic Torch Relay vehicle

The converted DAF horse box is being driven in front of the runners as they carry an Olympic torch along the relay route. It’s equipped with four cameras and a mixing desk, enabling a choice of views to be recorded and broadcast for 12 hours per day throughout the 70-day relay.

However, unlike most other outside broadcasts, the BBC torch relay isn’t using a satellite connection. Instead it’s staying connected to the studio by using some of the UK’s 3G mobile networks.

Combining the signals from eight 3G SIM cards is enabling the BBC’s media vehicle to transmit broadcast-quality video and audio as it drives along the relay route. The transmission is sent from the vehicle to the BBC’s studio, from where it’s broadcast almost-live on TV and via the internet with just a two-minute delay.

Mobile technology from Dutch company Triple-IT is making all this possible. The company’s Mobile Viewpoint Wireless Multiplex Terminal combines more than one 3G signal to provide more capacity and reliability than would otherwise be available.

The on-location technology is small enough to fit in a backpack that can be carried by one person - but in this case the BBC is using a little more horsepower.

A Sure Signal from Vodafone

Mark Bridge writes:

Today I've been using my mobile phone at home. For many people that’s not an unusual thing to do – but it is for me because, around here, coverage indoors isn’t particularly good. Downstairs it’s previously been non-existent. But this morning everything changed.

Physician uses cell phones to bring health care to the poor

Natalia Ardanza of voanews.com writes:

In Africa there is another use for mobile phones. Public Health workers in Kenya are now using mobile phones to gather health information from patients in remote areas and upload it to the internet for instant analysis at distant centers. And it is all happening thanks to Dr Joel Selanikio.

Making dumb touchscreen phones was a smart move

Mark Bridge writes:

I remember a report from last year that said ‘non-smart’ touchscreen handsets – generally those without a popular operating system – would be bad news for mobile operators.

Conventional touchscreen smartphones tended to result in higher-than-average ARPU thanks to their early-adopting tech-loving users, their web-friendly browsers, their email programs, their app-friendly operating systems and their fast 3G connectivity. However, dumber touchscreen devices – those with a manufacturer’s own proprietary OS and perhaps a clumsier browser – could generate 23% less ARPU than smarter phones. So, if touchscreen dumbphones weren’t good for networks… and weren’t really good for consumers either… manufacturers wouldn’t really bother with them. Right?

"Hello Nexus One" I say...

James Rosewell writes:

Mark’s been encouraging me to write an opinion piece on the Nexus One for the last few days and I’m finally putting fingers to keyboard to share my experiences. It’s taken so long because this phone has so many features. On a positive note I could go into details about the gorgeous screen, the Android Marketplace that will out-sell Apple’s over the next 18 months, the built-in satellite navigation service and the speedy processor that makes everything run smoothly in real time. Or on a less positive note, the touch screen keyboard that sucks (think carefully about this if you’re a heavy texter or emailer, it’s even worse than the original iPhone), the lack of ActiveSync for Calendars and Tasks, no support for WMA music files or the clunky zoom functions on the web browser.

However I’m going to focus on voice dictation. Nexus One is the first phone I’ve used with this feature.

The Amazon Kindle prepares to fight the Apple iPhone and Tablet

Mark Bridge writes:

Here’s a curious thing. Firstly, Amazon creates the Kindle. It starts selling the Kindle in the USA with a mobile deal that lets users download electronic books and newspapers wherever they are. Then it starts selling the Kindle to us in the UK, although – hang on a moment – it’s not talking about a UK mobile deal. Instead it still seems to be ‘roaming’ from the AT&T network. Next comes the larger-screen Kindle DX – also roaming away when it reaches our shores. And now Amazon is talking about third-party downloadable applications for the Kindle. Yes, a mobile device with downloadable apps. Hold that thought; I’ll be returning to it.
