Something I have been wondering and would like if someone with any knowledge could comment on:

When Telecoms CDMA network is finally turned off will the frequencies it has been using in 800Mhz be able to be transfered to the XT network so it can have more channels to use ("go faster")?

Can we expect the XT network will benefit from the CDMA closure?

XT with benefit from the CDMA closure but it will not be over night,

I'm sure Rachel Hunter said something similar. :)

John is right though that Telecom will have more carrier space for XT once CDMA is shutdown.

I have been assured that I will get 850 XT at home once the CDMA gets shutdown, at the moment I only see some 2100 and not much at that.

Why? CDMA comes in here loud enough and works well enough, just nothing on the UMTS network beyond the window.

I agree with Tritex.. If you don't get XT coverage now I am not sure how much improvement will happen when CDMA is shutdown. Again this is my own opinion and not gospel from Telecom. As the improvements will be capacity related (ie stuff will be able to go faster due to a larger carrier aka frequency range that can now be fully used for XT rather than split between CDMA and XT) rather than a coverage improvement.

Coverage depends on a whole raft of things and your choice of handset does have a role to play. For example I have been in some marginal coverage areas where I have no coverage or struggle to maintain a data / voice session on a smartphone (either Android or iPhone) where I get 2-3 bars and have no issues with my candybar Nokia phone and my Sierra Datacard with an antenna works a treat.

Have to agree with the above more spectrum for XT will not mean better coverage at all

Should WCDMA have as good coverage as CDMA, all other variables equal?

Also should the additional spectrum mean that we'll actually see speed increases?

Additional spectrum will allow Telecom to deploy additional carriers in the 850MHz band, and presumably also deploy DC HSPA+ on their network and potentially MIMO capabilities as well Vodafone already have this enabled and it allows real world speeds of up to ~30Mbps, there are certainly plenty of people who have been showing off in recent weeks with speedtest.net tests done on the new iPad.

At present the highest speed you're going to see on XT is around 15Mbps (real world average for a 21Mbps HSPA+ site). DC HSPA+ doubles this at present, but there is also the capability to bond additional channels, and in the future the ability to bond multiple channels on multiple bands, ie 2 x 850 or 900 MHz carriers + 2 x 2100MHz carriers which in a MIMO configuration could theoretically deliver several hundred Mbps.

So only for a DC HSPA+ device we'd see improvement?
A 21/14.4/7,2 device won't see any improvement really?

Deploying multiple carriers automatically doubles the capacity of a network, much like adding a 2nd lane to a single lane road. This means that performance should increase with regular devices also, if used in an area that has heavy use.

The two networks should mirror each other in coverage in practice, however there will be areas where CDMA is great and XT has nothing, and vice-versa.

The other thing is because it offers more available bandwidth could data plans be lifted with current user numbers without the risk of congestion on the current infrastructure?
