Case Study: LTE for real time news gathering by Sky News

Back in May, I had the pleasure of listening to a talk by Richard Pattison from Sky News where he talked about how they have managed to start replacing their Satellite trucks (which are extremely expensive to own and run) with the new solutions using LTE.

One of the advantage of LTE over 3G/HSPA+ is that the uplink is as good as the downlink which wasn't really the case in earlier generations. What this means is that you can use your phone to do a live video call and use that for broadcasting of real time information. The Sky News Tech team has some interesting tweets on this.




An example of the video quality could be seen from this clip here:

The Dejero App is an interesting one that can allow bonding of Cellular + WiFi and provide a combined data rate.


I was having a discussion yesterday on Twitter because we term this bonded cellular and WiFi as 4.5G. There are many proprietary solutions available for using them together but the standardised one is coming in standards soon.

Sky news have managed to set up new standards by having 12 feeds simultaneously broadcasting  (all based on Iphones and Ipads) during the European elections.



All this has been possible due to an amazing 4G network by EE and being able to negotiate a 500GB (0.5TB) data package.


Anyway, you can read the complete paper below:

Video Calling: Boon or Bane?

When 3G was launched, the operators were clueless as to what 3G can do. The only way according to them to sell 3G was to to market 'Video calling'.

I am not sure how many of you have used Video calling, but I love it. Shame that the operators have priced it so ridiculously that I only used it when I had them inclusive in my package. Otherwise paying £0.50 per min seems exorbitant to me.

We have so many other options like Google Chat with Video and Skype Video chat available which is very convenient (and far much cheaper) according to me. Skype client is available on mobiles but still Video is not included. Its just matter of time before Video calling is included part of the VoIP client. All handset manufacturers are scared to include the feature so as to avoid the ire of operators. Maybe we will have to leave it to iPhone again to break this barrier as well.

The following is from Reuters news article:

Research in Motion Ltd says it is far from certain that video will become the "killer app" that defines smartphones, but even so the BlackBerry maker says developing more efficient delivery is necessary to prevent video from choking airwaves.

The popularity of feature-rich smartphones such as the BlackBerry, Apple's iPhone, and Motorola's Droid has surged, but they use as much as 30 times as much bandwidth as regular mobile phones to run the applications, or "apps," that make them so popular.

The surge in traffic triggered by video and other apps has led to more dropped calls and choppy service. As video on smartphones becomes more popular, it is leading to more congestion, and forcing carriers to spend billions to upgrade networks and buy more wireless spectrum.

"I still don't know and I don't think anyone knows if video is a killer app for smartphones," RIM Co-CEO Mike Lazaridis said at a conference hosted by a unit of Toronto Dominion Bank on Friday. "I don't particularly think it is."

Lazaridis said that even if video did not become the defining app for smartphones, it is already presenting a big challenge to networks.

Analysts have praised Waterloo, Ontario-based RIM for its relatively bandwidth-light BlackBerrys, which route most emails through the company's own servers. This is a legacy of the company's earlier days when it was seeking a faster, more secure mobile email service.

RIM also sends web browsing, Facebook, Twitter, and data from a wide number of BlackBerry apps through its own servers.

That makes browsing and using apps on a BlackBerry three to eight times as efficient bandwidth-wise as on the devices of RIM's rivals, said Lazaridis.

"What that means for the carrier, though, is after they have committed all those billions of dollars on new network technology and new network spectrum, they can have three BlackBerrys using the same network capacity as one of the other smartphones."

Lazaridis said RIM would invest more in technology that provides efficiencies to carriers, including when it comes to video.

He pointed to RIM's 2006 acquisition of SlipStream, which specializes in data acceleration, compression and network optimization technology.

"They had some amazing technologies for compressing everything from web content, documents, and video. So, you never know, the research that we do is very important, it's always borne fruit and we are hoping that we can continue to ... provide tangible efficiencies to the carriers."
