Hi, just wondering if Vodafone are still expanding 1800mhz 4g, or is all the effort going into 700mhz 4g?

Just wondering, as I like my phone, but it doesn't do 700mhz 4g, and where I live (south Hamilton) 1800mhz 4g is marginal.

The focus is on deploying 4G across 3 bands - 700MHz, 1800MHz and 2600MHz. Pretty much every rural site that has 700MHz also has 1800MHz and many have 2600MHz, meanwhile many urban sites that don't yet have 700MHz will have both 1800MHz and 2600MHz.

 

Because of the benefits of carrier aggregation (which is now possible across the whole 3 bands with a supported device) it makes sense for Vodafone to be deploying the whole 3 bands.

700Mhz is now deployed on a couple of sites in Auckland CBD

Short answer is "yes". There's still more 1800MHz going in, and that'll keep on going, along with the other stuff the others mentioned, plus more.

What about sites that are also using 1800MHZ GSM do you still have enough spectrum for both GSM and LTE.

That's probably more one for JohnR, but I'm sure the answer is yes.

Seems a waste of good spectrum to use it for 2G, but I am sure they can carve off a tiny slice at once side of the new highway to leave the dirt track for 2G devices to trundle along.

GSM still used for smart meters.

From what I've been told, modern base stations can run a 2G / 4G service on the same slice of spectrum. Therefore you can keep 2G services (eg M2M) connections going for a long time to come without using any dedicated 2G spectrum.

I believe any 1800 used for 2G is all pretty much gone. It was only ever used for extra capacity in the hay days of 2G. I doubt there are any capacity issues on 2G these days, so simpler to keep it on 900 only.

 

 





Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

And since Spark don't offer a 2G service [ IIRC they went from D-AMPS to GSM-3G and never had 2G], this gives Vodafone a reasonably valuable Unique Selling Point for the M2M market until low-data-rate LTE becomes cheaply available.
Considering the electricity gentailers have installed several hundred thousand so-called 'smart' meters that have 2G modems built in, and their bean counters will doubtless expect to get twenty years working life out of them, this is really quite a good USP and we can expect Voda to offer 2G for quite a while

2Degrees have 2G services running as well, although in remote areas, roaming onto VF would be needed - the irony.

They went from D AMPS to CDMA and then after the cock up with GSM then went dedicated 3G UMTS 850/2100.
