Not sure but I think decription wrote something on this. Can't find it.

Does the iPhone on a NextG operate at NextG speed or 3G.
Is that assumption correct?
If Telstra sell the iPhone as I think they will would it only operate at 3G speed not NextG.

NextG the replacement for CDMA has a larger coverage than 3G in remote areas. So does this mean the iPhone being no good for use in remote areas or away from the city's? Dropping back to slower GSM? speed.

I believe I've seen it specified as NextG compatible but that may be different to running on NextG.

Aren't optus rolling out a NextG network equivalent in the future?

NextG is 3G, it can run as high s 14.4mbps but the iPhone is only rated at 3.6mbps, like most NextG phones.

NextG is the same technology as Optus' HSDPA network, Vodafone's HSDPA network and 3's entire network. That's why it's sometimes referred to as SameG.

Although it will only run a max of 3.6mbps and NextG is theoretically 14.4mbps that doesn't mean anything as all of Telstra's phones are 3.6 anyway, there might be some 7.2mbps phones though.

Next G is 3G, its just tel$tr's name for it. if you can get an iPhone unlocked and put a Next G SIM in it it will work where ever tel$tra's 3G service has coverage.

The 3G iphone can run on 850Mhz 3G (aka NextG), i believe the chipset limits it to 3000/364 connection but that should be plenty for a mobile device (nextg data rates are insanely expensive anyway)

It would be great to use Telstra's 3G network as the coverage is far superior. Alas, I may as well bend over and let them have at it.

How does that relate to coverage wise?

Looking at the coverage maps (vic) on the telstra site NextG covers a much larger area than 3G.

The nokia phone I have is a 3g only phone and can't take advantage of the larger NextG coverage.
Won't the iPhone be the same? Won't telstra one day phase out the 3G coverage? Why run two networks.

I did think though NextG phones were quicker that 3G phones. Seems not.

*sigh*
nextG IS 3G......... coverage is the same as 3G because 3G = NextG = 3G = NextG...


oh by the way, did you know that nextG is the same as 3G?
what nokia? and why couldnt it take advantage of the nextG networks?

if my old Dopod 838pro (HTC Hermes) could take advantage of Vodafones 3G network... and my dads imate Jasjam (HTC Hermes again!) can take advantage of telstras NextG at 10,000 feet over the tanami desert... i think the iPhone will do the same.
it is running the 850mhz NextG network that tel$tra are using.

Ok, to clarify what's been said:

• NextG is 3G.
• The only important difference between Telstra's '3G' and 'NextG' networks is the frequency they use for radio transmission.
• Not all phones are compatible with the 'NextG' frequency (your Nokia for example).
• The iPhone is compatible with the NextG frequency.

Don't listen to the Telstra marketing drivel. NextG is only 3G using a different radio 'channel'. They probably will turn their '3G' network off one day but it wont matter to iPhone users since they wont be using it anyway.

Any of the ones which don't have the hardware for 850MHz transmission wont use the 'NextG' network. When Testra first started pushing the SameG branding there were practically no phones available for it. My crappy Nokia can't do 850MHz transmission.

Well to be clear, there are two technologies when talking about 3G, there's normal UMTS and there's HSDPA.

HSDPA and UMTS are both classified as 3G technologies, which is where the confusion comes from. HSDPA is a lot faster than UMTS. When Telstra went from UMTS, which everyone called 3G, and upgraded to HSDPA, they called it NextG, even though it's classified as 3G.

Vodafone Optus and Three all have HSDPA now, but instead of calling it NextG or 4G or anything, they just continued calling it 3G. This gives the false impression Telstra has some kind of Next Generation Phone technology.

The iPhone supports HSDPA meaning it is NextG and much faster than Telstra's '3G'. However it is just as fast on Vodafone, Optus and 3, which all have HSDPA networks. Telstra's HSDPA network is faster than everyone elses, but mopst phones (iPhone included) max out at 3.6mbps, which all the networks support.

In terms of coverage the iPhone (if unlocked and put on Telstra) will work in all NextG coverage areas.

Next G is in fact faster than all the other 3G networks, it is fact 3.5G and i understand by the end of this year it will be 4G. It offers true speeds across the whole country rather than just metro areas and i think it is currently the fastest mobile network in the world. The network is 850Mhz and the 3G networks are 2100Mhz, i do not know enough to explain that but the 850mhz in this case is faster.

[quote=jeloz;530089]I know it's faster, but all the networks are HSDPA, or 3.5G. Telstra's is just faster.

Would be awesome if the iPhone supported 14.4mbit, mmmmm

Sorry for asking!

My comments have been purely based on reading , it is a confusing issue that is for sure....

[quote=jeloz;530089]sorry jeloz, that really is just tel$tra spin. its 3G and always will be whatever the marketing guys say. there are a number of frequencies currently used by 3G, 850, 900, 1900 & 2100MHz for instance.

its not the frequency that makes 3G faster but rather the technology that utilises the network, tel$tra is no longer the only network in the world claiming up to 14.4Mbps - a speed completely unachievable on any 3G phones and supported by very little hardware. (a few modems).

its also a theoretical maximimum dependent on a number of external factors.

it is believed the3G technology can be stretched to allow speeds as high as 42Mbps in the future.

in practical terms any 3G network providing up to about 3.6Mbps is going to any amount fast enough for a phone - thats over twice the speed of a normal 1.5Mb ADSL service which most people find just fine for home internet let alone a phone.

unless you are downloading massive files like Usenet or P2P its hard to see any advantage in higher speeds like proposed for 3G, you wont see the difference with email or browsing anyway.
