In terms of mobile phones, we desperately needed to move from the 025 network, with its very limited capabilities. All over the world analogue networks, including the world’s biggest, AT& T, were being phased out and handsets were no longer being produced. As nothing about technology stands still, we believed it was very important to get a third-generation product to market at speed. We knew there would be a choice of paths to whatever the next-generation technology was: we went with CDMA mobile technology for our network, partly because CDMA was the major technology used for mobile communications in North America, including by one of our then owners, Bell Atlantic, and it was popular throughout Asia, but also because we did not have a licence for GSM, which had a higher number of subscribers worldwide. (In fact, Telecom originally did have a licence for GSM some years before I joined, as did Bell South, which was later bought by Vodafone. I understood from Roderick [Deane, former Telecom CEO] that the government had required Telecom to sell its licence due to the view that it wouldn’t be good for competition for the two main players to be on the same technology.)

 

If this was indeed the case it sounds patently ridiculous IMO, especially given the fact that today we have (at least) two networks who operate exactly like that.

 

But that was a long time ago, and (as has been pointed out already) things have changed quite a bit since then.

 

 

If only GSM 850 existed back then we might have bypassed the IS54 and IS136 junk that was a dead end technology.

Interesting video from Australia, some phones that support 4G VoLTE do not support emergency calls over the protocol.

Good old Telstra, choosing a standard that doesn't quite match other providers. 

 

Back in the day we had SS7 which was ( maybe still is) the international signalling standard and other agreed protocols. 

 

I can't but help think that something like this should have been applied with VoLTE.

Sounds like it hasn't really accepted that its no longer "the phone company"...

What VoLTE & 5G system does Spark, OneNZ and 2Degrees use?

 

Are they the same standards or different than other telco's overseas?

I'm curious what happens if a shop sells a phone that is not VoLTE compatible? Would the CGA cover it? For example, I could get this Google Pixel 3XL from Reebelo for $479 (which seems very expensive for such an old phone, but the point is will it work?):

I've raised this question with Consumer.org.nz a while ago. I hate the contraction of options that this change will usher in (along with changes that severely hobble 3rd party ROMs) but it seems like a whole lot of retailers will be in trouble selling the variety of handsets still available now when people's reasonable expectation for the useful life of a phone hits the wall.

What did Consumer say when you spoke to them?

 

From memory most of the carriers stopped selling 2G/3G devices a while ago.

New business idea: Phone rental company for tourists.

 

 

It would be a bit of a hassle migrating your set up to a rental handset. I think it would probably end up making more sense to increase availability of portable cellular hotspots which could be cheaper to replace when standards change and extend the useful life of orphaned handsets (you could rent in country but a market would obviously exist for global models) and using either VoWiFi or, for more portability and long term compatibility, using VoIP instead of a carrier voice number.

Buying from a carrier is fine in terms of compatibility with the changes, I just dislike the market being restricted in the number of available manufacturers and models plus outlets (though PriceSpy is getting less useful at showing all retailers and stock these days, see https://pricespy.co.nz/category.php?direction=asc&k=103&sort=price for examples of models outside the carriers' approved lists)

May as well go back to the old Telecom days of sending out loan (GSM) handsets for anyone roaming to a non-CDMA country 😀

My read of this is you can have  4G/5G phone, it may have Volte, but if 'that' Network has not decided to support 'that' Phone you are stuffed.

The issue is not if you have a 4G/5G Phone or not, rather if 'that' Phone has support of 'that' carrier.

While 3G exists you think its all fine, not knowing that your voice calls are actually all 3G, only your data is reliably 4G/5G.
So cutoff day could be a bit of surprise ?
People with older model phones that are 4G so you think you are ok but.
As I understood it but surely not?

I started watching it but gave up part way through. I don't know SS7 intimately but I do remember a fair bit about inband signalling which is what he is talking about with the folklore story of Jobs and Wozniac calling the Pope.

 

There were so many errors that I couldn't sure he had the SS7 stuff correct.

 

For a start DTMF signalling wasn't the solution to problems with long distance dial pulses. Single tone in band signalling was that solution. Sure DTMF may have been used in some instances but it came along well after  single tone inband signalling was in use.

 

Second he talks about 2600 Hz being the inband frequency. It may well have been in the US, they also used 2400 Hz. We used 2280 Hz as did I supspect a lot of British Commonwealth countries as our systems in New Zealand were bought from the British manufacturers. There wasn't just one inband frequency. Not only did you have to get the frequency correct you also needed to get the length of the tone correct. The thought you could inject a 2600 Hz signal in the US and expect that it will come out the other end in somewhere like Italy and achieve the desired results is bordering on being unbelievable especially when you consider my next point.

 

Lastly all of our circuits in New Zealand had notch filters to filter out any 2280 Hz signal to stop any extraneous signals from outside the network getting into the network. I'd bet all the tea in China this was standard everywhere. Sure you'd get the odd rogue filter that would go off frequency but that was rare.

 

Too many red flags for me to bother watching the rest of it.

Is this the start of the end of the cellphone.

Looks more like cloud PBX system to  me.
