Firebreaker: From my understanding you don't need more bandwidth with LTE advanced in fact you could have much less, of course if I am wrong I would love to be corrected.


Just for a quick comparison:
2G is usually using 200KHz bandwidth per channel, but operators would need minimum 4MHz (20 channels) and it can provide  480Kbps DL speed (EDGE)

3G is usually using 5MHz bandwidth per channel and it can provide 42Mbps DL and 11.5Mbps UL

LTE is usually using 10-20MHz bandwidth per channel and it can provide 300Mbps DL and 75Mbps UL

LTE Advance is usually using 20MHz bandwidth per channel and can provide 1Gbps DL and 500Mbps UL. By using channel aggregation (4 channels max= 100MHz total) it can provide up to 5Gbps DL speed as it was tested by NTT Docomo back in 2007.

(DL= downlink or download, UL= uplink or upload)

The real 4G technology is LTE-Advanced according to 3GPP standards.

I hope it helps. The numbers above are approximate and in ideal conditions. Usually it is lower than these.




I is a kollege stoodent. Bee nice.

Yes this was very helpful thanks! So why are mobile data speeds increase but home broadband is given the back burner?

Where is home broadband being given the back burner?

In the last couple of years speeds have gone from 7.6Mbps ADSL1 to ~20Mbps ADSL2+ to 70Mbps VDSL2 if you're close enough to a cabinet to 100Mbps or 1Gbps if you're on fibre.

Can anyone else get into the vodagone 4G coverage map?

I get an error when trying to access http://4g.vodafone.co.nz/#COVERAGE that says the web site needs a different Google Maps API key. If I click OK it says my browser doesn't support gmaps.

Using Chrome but also tested on IE with same error.

It's linked from the vodafone homepage so a bit strange if its a problem at their end.

Noticed some guys putting up some new equipment on a lamppost near the McClymonts Rd motorway overbridge in Albany the last few days. Is it DC-HSDPA, LTE or non-Vodafone related?

First little outing with Vodafone 4G, this one taken near top of Dominion Road. Feels a lot like when I first got broadband, just a big leap over what I'm used to (and not just mobile broadband either).

Now if only Vodafone would compensate me for the data I am burning with my speed testing OCD.

Yeah, that was better than a few results I had in better coverage though.

Not the normal UFB plans I don't think, but I know of at least one school with a 1gbit link to KAREN.

i think fibre is meant to be 'unlimited' so they could provide you with any connection speed in your wildest dreams if your bank balance is large enough

Looks like Vodafone turn on 4G for parts of Newmarket over the weekend (which were always included in the 4G coverage map.)

Speedtest:
