bonkiebonks: assuming they were in the same location, would the signal be as good? Cause they're running on the same frequency, except different technologies? i.e. would it still be able to penetrate walls as well?
If I stand under a radio station transmitter with my iPod and my Griffin iTrip, set to the same frequency as say, The Rock, would the signal be as good? Cause they're running on the same frequency, except different technologies?
So you see that the answer clearly depends on other things, like output power for a start, not to mention direction that some equipment is aimed at.
I am sure some RF gurus will step in for further explanation. But suffice to say, the fact that they are on the same frequency is where the similarity ends.

Ok. :) Not quite. They're on the same frequency, so if the sites are in the same place, then yes, depending on the EIRP, you'll be getting a **similar** sort of signal strength due to the fact that propagation on an 850MHz signal is much better than a 2.1GHz signal.

They're the same technology tony :P .. the output power is many thousands of times more on the broadcast transmission though :) so yeah, you'll just get The Rock - although, the power output under the mast is actually significantly less than that about 100 metres to your left.
In fact, under the mast on Mt Cargill is the only place on that hill that the s-meter on my transceiver actually comes off the top stop.

That's the kicker.. :) The antennas will be omni's, except for in very specific situations. it's the output power that'll matter.
From a services perspective the two telecom networks are treated as one network. So will Telecom continue to sell old CDMA phones for the forseeable future then? As a low-cost option for customers? Or will there be an rapid cutover to only selling devices for the new network?
I do not think so, that would undermine their plans as far as I can tell. On the old page describing the new network, it stated that when a majority (51%, I assume) of their customers move from CDMA that network will be progressively decommisioned.
I think that they will stop selling CDMA on the day, and potentially eventually force everyone over, otherwise they'll be maintaining two networks which wouldn't be worthwhile.
Also, CDMA is more expensive to buy, so how is it a cheaper option? Have you noticed with vodafone cells (i.e 3G Handsets) you get way more bang for your buck.
A Nokia 1325 is far cheaper than the cheapest 3G phones, and if you just want to call it does the same job (maybe even better, it's smaller, lighter, fits in your pocket better and probably has a longer talk time)
they will probably continue to sell CDMA phones until their stock runs down I would think.
Hansets would have to be ordered many months in advance, and launch dates can change too. This means they will probably have a not insignificant amount of surplus stock (to cover in case the netowrk launch was delayed) which they will need to get rid of very quickly.
Unless they can offload their surplus stock to some other carrier(unlikely since NZ CDMA generally doesn't work across other country's CDMA networks) then they will need to get rid of them somehow.
Depending on how good their planning is, there might be anything from 1 month to 6 months of a 'fire sale' on CDMA stock.
CDMA won't be closing down for a couple of years at least I imagine (think how long TDMA stayed open after CDMA launched) so you have plnety of time to use a CDMA device if one is sufficiently cheap.
Having said that, if the economics stak up it might be better to not bother doing that and just write off the old stock.
i was talking to a unamed telecom rep, he mentioned from launch date, there should be 16 models available, lower end to high end. so that will be good. no point screwing around. get this network out there from day 1

I've been watching the Telecom site for a few months now for info on the new network and all I've seen is more and more models dropping off the mobile page, which which tend to suggest, as stated above, that they probably ceased ordering CDMA stock quite a while back and will sell out all existing stock. Whether they slash the price or not, that's another question.......
