jvorback: Talking to our company's mobile account manager, Telecom's T3G service can already handle live video calling - the just haven't bothered turning it on because it's had such as lukewarm response everywhere else in the world.

After all, both Telecom and Vodafone use CDMA technology for their 3G networks, so it would make sense that if one can do it so can the other. The feedback that I've had from people who have seen video calling in action is that the quality is pretty poor, especially if there's any movement involved (forget trying to video someone waterskiing down a flooded street - nice commercial, not very realistic)

The problem that Vodafone have is that this type of technology appeals mainly to kids, and most of them can't afford the cost of the phone. And even if they did get one, chances are that no one else they know would have one. So... who that gonna call?

As crappy as txt seems to me, it's still the biggest selling point among kids. Telecom's $10 bucks a month plan really was a master-stroke.

You seem to forget that Video Calling is an evolutionary process, in terms of the network performance. Currently the Vodafone UMTS 3G Network is 384 download/64 upload & latency is quite high, naturally this will effect the Video Calling quality. I have used it & find it fine, it does the job & I know it will only get better, due to the fact that it's on a mobile, the uses are even more greater. The network coverage will also increase significantly over the next 12-18 months.

Also, the speed will be increased significantly with the implementation of HSDPA & HSUPA & the Video Quality WILL improve "significantly". The Video Calling technology is very new, Vodafone introduced into New Zealand in August, hence like any electronic product it's expensive when it first comes out. The cost of the phones WILL come down, they already are right now. I also disagree with your statement about this technology only being good for kids, it has a whole multitude of uses, limited only by your imagination for adults as well :-)

Just want to register my opinion along with Grantis and sbiddle, video calling has many applications, handset price has dropped like a dropped thing on drop day, Telecom cant 'switch it on' because it hasnt been implemented, but will be soon (inside 1 year perhaps?). Low uptake is a problem for any new service that requires both parties to have the technology (e.g. PSTN video calling), but numbers will grow, and PC<>Phone vid calling will help, as will inter-network video calling. I beleieve Telecom will do it when the following two conditions are met: 1. Network speeds improve (esp upload) & 2. Handset availability. Hmm bad grammar - 'scuse me, mybad.

WCDMA video calling has nothing to do with the network speed or latency - the video is not carried as IP traffic but has it's own dedicated 64k channel.

Correct Video calling is just a 64k CSD connection

In that case, it's not really a '3G' feature, is it?

It still uses the 3G air interface for the connection so yes it is a 3G feature for sure

Oh really, I never knew that. I assumed it would be all tied into the current speed of 384/64. Thanks very much for that. Are Vodafone going to improve the quality of this connection in the near future then? What is the next evolutionary path for Video Calling?

I have. But I want to know specifics about Vodafone New Zealand, not countries overseas. It would be nice if Vodafone released information with "approximate" timeframes as to when new technologies will be implemented.

As a customer, knowing approximately when Video Calling quality will be improved (it's ok at the moment, but I know it can get much better) would be nice to know. Also, when Vodafone removed the link on their website about where new cellsites would be implemented was a shame, as I found it very handy as a customer to know where coverage would be improved. It would of been great if this was used with the new 3G cellsites as well, but I understand they removed it because of security reasons (vandalism of cellsites being one of the reasons).

I would ask this in a private message - no need to have personal information disclosed on the public forums.

Everyone knows he works for Vodafone, I presume he divulged the information. Therefore if he chooses to divulge the departemnt he works in, isn't it his choice to do so, or not? I'm hardly asking for his address, phone number am I?
