CDMA2000 1xEV-DO Rev. A is optimized for packet data service, offering peak data rates of up to 3.1 Mbps on the forward link and up to 1.8 Mbps on the reverse link. It also supports QoS for delay-sensitive applications, including a variety of IP-based services such as VoIP and real-time conversational services such as push to talk, video telephony, low-delay gaming and "instant multimedia" (an extension of push to talk that combines immediate voice with simultaneous delivery of video and pictures). Another key attribute is support for 1xEV-DO Gold Multicast, which would enable the delivery of high-quality video and audio to a large number of users simultaneously. If standards progress permits, Qualcomm's MSM6800 chipset will also support 1xEV-DO Platinum Multicast.

From a biased one eyed GSM fan's point of view I can definately agree that it rocks.. Hopefully it does perform that well in real world tests, UMTS was great on paper as well! :-)

its a bit of a flop for voda cause its so new at at launch time handsets were so expensive.

telecoms 3g has much more extensive coverage (especially by the next 12 months) than voda did at launch time.

You also need to look at something more obvious - what use really is a video call? Video phones have been around for 20+ years for PSTN lines yet nobody has one!

Video Calling a flop? It's been out for just over 4 months, how can you base a decision on such a new service in 4 months?? I know of a few people who work for Vodafone & they tell me that Video Calling is proving very popular.

Once more people buy 3G handsets (which they are) & the coverage increases more (which it is) things will only get better & more popular IMHO.

Perhaps the "Mobility" has something to do with it. It also has various handy business applications & it's damn fun!

Trust me its a flop. One of my relations is a major share holder in voda and they arent happy with what they got for $700 million. Just like the very interesting reason they stopped screening the video calling ads. Its handy having a relation he can tell me the inside info and I also got a sharp v902 very cool but very fat but it was ok for free i guess. But the problem is i only know one person with video calling.

That sounds like a great Tui billboard..

Exactly who is this "relation"? Considering Vodafone NZ is 100% owned by the Vodafone Group you'd have to be a worth probably $50+ billion just to be a small shareholder in Vodafone.

There definately are great uses for it and the mobility aspect is the reason that it is popular while PSTN video phones aren't. I still find holding a phone at arms length and talking on speakerphone very whierd though! Like people who were looked like idiots walking around with Bluetooth headsets on I guess it's something society will eventually accept! :-)

It will become more acceptable to use Video Calling.

Hell, I remember when Mobile phones first come out, we use to call them Yuppie Phones & people using them looked "weird" & out of place. ;-)

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.

I would suggest that you look elsewhere for an account manager if this is his level of knowledge. Telecom's current EVDO network does not support video calling, it's not just a matter of turning it on. No CDMA networks anywhere in the world currently support video calling and there are no currently available CDMA handsets that support it. By the end of this year it will be a different story, Telecom will probably have video calling available on their network.

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)

Rather than justlistening to feedback from other people I suggest you try video calling yourself. It can be grainy but a lot of this is depends on the model of phone you use as well and the quality of the CMOS sensor in the front, some video calling is crap, other phones are very good. Video calling is also quite low bandwidth (64kbps) so any fast movement is going to cause some problems.

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?

Video calling seems to have mainstream appeal and if you looked around the streets lately it seems to be pretty trendy for young people to be video calling each other. Whether that trend will continue once it's no longer free is a different story but the video calling aspect of 3G has been a big drawcard even if people aren't using it all the time.
