Last week, I was at the TeleManagement Forum’s (TMF) Africa Summit event in Johannesburg, South Africa. The main reason for me attending was to finish of my TMF certifications (I am level 3 currently) in the process framework (eTOM) – if I have passed the exam, I will be Level 4 certified. It was a really tough exam (75% pass mark) so I don’t know if I did enough to get over the line’. Regardless, the event was well attended with 200-230 attendees for the two days of the conference. It was interesting to hear the presenter’s thoughts on telco usage within Africa into the future. Many seemed to think that video would drive future traffic for telcos. I am not so sure. I n other markets around the world, video was also projected to drive 3G network adoption, yet this has not happened anywhere. Why do all these people think that Africa will be different? I see similar usage patterns in parts of Asia, yet Video has not take off there. Skype carries many more voice only calls than video calls. Apple’s Facetime video chat hasn’t taken off like Apple predicted. 3G video calls makes a tiny proportion of all calls made. Personally, I think that voice (despite it’s declining popularity relatively speaking in the developed world) will remain the key application, especially voice over LTE for the foreseeable future in Africa. I also think that social networking (be it Facebook, freindster, MySpace or some other African specific tool) will drive consumer data (LTE) traffic. Humans are social animals, and I think these sorts of social interactions will apply just as much in the African scenario as it has in others.

Nokia e71 making a video call
Since I penned my last post, I have done some more reading on Facetime and watch Steve Job’s launch of Facetime. While I will happily admit that Apple have in fact used some standards within their Facetime Technology (Jobs lists H.264, AAC, SIP, STUN, TURN, ICE, RTP, SRTP as all being used), I am somewhat bemused by the “standards” discussion that most of the media seem to be focusing on with regard to Facetime. Almost everyone that refers to compliance with standards is talking about interoperability with current PC based video chat capabilities – from the likes of Skype, MS Messenger, GTalk and others. Am I the only one that has noticed the iPhone 4 is not a PC and is in fact a mobile phone? Why is it that no one else is questioning interoperability with existing video chat capable mobile phones?
After thinking on this for a little while, I guess it might be that most of the media coverage about the iPhone 4 is coming from the USA – where is was launched. It’s only natural. The problem with the US telecoms market is that it is not representative of the rest of the world – who has had video calling for ages and don’t really use it. Perhaps it was the overflowing Apple coolaid fountain in the iPhone 4 launch that got the audience clapping when Jobs placed a video call, or perhaps it was just that they had never seen a video call before – I wasn’t there so I cant be sure. Right now, the Facetime capability on the iPhone 4 is only for WiFi connections – which makes it pretty limiting. Apparently, there is no setup required, no buddylist, you just use the phone number to make a video call – which is the way video calling already works (see the screen dump of my phone to the right and the short video below), but the WiFi limitation on the iPhone 4 will mean that you have to guess when the recipient is WiFi connected. At least with the standard 3GPP video call, the networks are ubiquitous enough to pretty much guarantee that if the recipient is connected to a network, they can receive a video or at least a phone call. Job’s didn’t explain what would happen if the recipient was not WiFi connected – does it just make a voice call instead? I hope so.
(Note: the original post had a flash video of a video call conducted from my Nokia e71 phone – I’m trying to find the original recording of the call (3GVideoCall/3GVideoCall_controller.swf) and I’ll update this post if I can find it)
If you look at the pixelation and general poor quality of the video call, consider that I am in a UMTS coverage area, not HSPA (the phone would indicate 3.5G if I were), so this is what was available more than seven years ago in Australia, longer in other countries. If I was in a HSDPA coverage area, I would expect the video call to be higher quality due to the increase bandwidth available.
I recall in 2003, Hutchison 3 launched their 3G network in Australia with much fan-fair. Video calls was a key part of the 3G launch in Australia for all of the telcos. This article from the 14Apr03 Sydney Morning Herald (on day before the first official 3G network in Australia) illustrates what I am talking about. The authors say that the network’s “…main feature is that it makes video calling possible via mobile phone.” Think about it for a second. That’s from more than seven years ago and Australia was far from the first country to get a 3G network. A lifetime in today’s technology evolution. Still the crowds clapped and cheered as Jobs made a Video call. If I had have been in the audience, I think I would have yawned at that point.
The other interesting thing that I noticed in job’s speech as his swipe at the Telcos. He implied that they needed to get their networks in order to support video calls. Evidence from the rest of the world would suggest that is not the case – perhaps it is in the USA, or perhaps he is trying to deflect blame for not allowing Facetime over 3G connections away from Apple and back to the likes of AT&T who have copped a lot of flack over their alleged influence on Apple’s Application store policies involving applications that could be seen to be competitive with services from AT&T. I am not sure how much stick AT&T deserve on that front, but it’s pretty obvious from job’s comment that he is not in love with carriers – and certainly from what I’ve seen, carriers are not in love with Apple. It might be interesting to see how long the relationship lasts. My guess is that as long as Apple devices continue to be popular, both parties will be forced to share the same bed.
On another related point, I have been searching the Internet to find what standards body Apple submitted Facetime to for certification – Jobs says in the launch that it will be done “tomorrow” – this could be marketing speak for ‘in the future’ or it could literally mean the day after he launched the iPhone 4. If anyone knows please let me know – I want to have a look into the way Facetime works.
Thanks very much to my colleague Geoff Nicholls for taking the Video Call in the video above.
I came across this article today – Apple wanting to propose their new Facetime technology for video chat now that they finally have a camera on the front of their iPhone 4. I’m now on my second phone with a camera on the surface of the phone (that’s at least four years that my phones have had video chat capabilities) which has not proved to be much more than a curiosity where Telcos have launched it around the world. I recall the first 3G network launch in Australia – for Hutchinson’s ‘3’ network – video chat was seen as the next big thing – the killer application, yet apart from featuring in some reality shows on the TV, very few people used it. I wonder why Steve Jobs thinks this will be any different. At least the video chat capabilities that are in the market already have a standard that they comply with which means that on my Nokia phone, I can have a video call with someone on a (say) Motorola phone. With Apple’s Facetime, it’s only iPhones 4 to iPhone 4 (which does not support a 4G network like LTE or WiMax I hasten to add). If Apple really is worried about standards as the Computerworld article suggests, then I have to ask why doesn’t Apple make their software comply with existing 3GPP Video call standards instead of ‘inventing their own’. If Apple were truly concerned about interoperability, that would have been a more sensible path.
According to Wikipedia, in Q2 2007 there were “… over 131 million UMTS users (and hence potential videophone users), on 134 networks in 59 countries.”. Today, in 2010, I would feel very confident in doubling those figures given the rate at which UMTS networks (and more latterly, HSPA networks) have been deployed throughout the world. Of note is that the Chinese 3G standard (TD-SCDMA) also supports the same video call standard protocol. That protocol (3G-324M – See this article from commdesign.com for a great explanation of the protocol and it’s history – from way back in 2003!) has been around for a while and yes, it was developed because the original UMTS networks couldn’t support IPv6 or the low latency connectivity to provide a good quality video call over a purely IP infrastructure. But, things have changed with LTE gathering steam all around the world (110 telcos across 48 countries according to 3GPP) and mobile WiMax being deployed in the USA by Sprint and at a few other locations around the world (See WiMax Forum’s April 2010 report – note that the majority of these WiMax deployments are not for mobile WiMax and as far as I know, Sprint are the first to be actively deploying WiMax enabled mobile phones as opposed to mobile broadband USB modems) so, perhaps it is time to revisit those video calling standards and update them with something that can take advantage of these faster networks. I think that would be a valid thing to do right now. If it were up to me, I would be looking at SIP based solutions and learning from the success that companies like Skype have had with their video calling (albeit only on PCs and with proprietary technology) – wouldn’t it be great if you could video call anyone from any device? I guess the thing that annoys me most about Apple’s arrogance is to ignore the prior work in the field. Wouldn’t it be better to make Facetime compatible with the hundreds of millions of handsets already deployed rather than introduce yet another incompatible technology and proclaim it as “… going to be a standard”.
