Can anyone confirm?

When XT were the most expensive data carrier i got speeds of 7Mbps+

But I switched to Voda and go no coverage. Switched to 2D and got 7Mbps+ off peak and 2Mbps during working hours.


Since they were the first to become the cheapest ($19/500Mb) i signed back to XT to get the best coverage. Best coverage I get, but worst speed. I'm not complaining because cheapest = most congested, I udnerstand that. 

Normally it gets pretty congested during working hours in Dunedin I get 1-2Mbps.

Since the Uni restarted I'm getting 300-500kbps in CBD

I am considering 2D (and Voda if/when they do 900MHz in hilly Dunedin) ...

Just saying :D

No reports of issues.

Have you tried speaking to the mobile helpdesk and see what's going on.

There has been significant upgrades going on in Dunedin... So I would be interested to know if there were significant slowdowns.

My office looks directly at the Gen-i building/Dunedin central exchange and is about 50m away. I'm getting: Test 1: 0.33Mbps down, 0.06Mbps Up, Test 2: 5.39Mbps Down, .91Mbps Up, Test 3: 6.07Mbps down, 0.93Mbps Up - on a Nexus 4.

Any upgrade plans over towards South Dunedin / St Kilda?
You go into a building and your data connection just crawls or doesn't work at all (1 bar on iphone 4)

no ... i doubt there's anything they can do. there'll be alot of do this do that turn this off turn this on reset this etc ...

the thing is off peak you get 4-7Mbps (depending on location) peak is a crawl. always have full bars of reception (whatever that means)

so there you go :)

I'm out Waverley way and around lunchtime during the week I always get very very slow performance on a XT Sierra Wireless AirCard 326U - dialup is quicker at times!

I've just got a Huawei Mobile WiFi E587 for testing, so hopefully this will at least make it bearable around these peak times.

Yes voice couldn't get much better except for a wider audio frequency range, but I suspect that would be a huge undertaking on all hardware and software platforms involved. I'm comparing this to the likes of Microsoft Lync - sorry off topic there :)

AMR-WB is supported by most mid to high end modern phones but no networks in NZ support it.

Its oweek in waikato. The cell tower on campus can't cope with the sheer quantity of people using data on it, here's a speed test I did the other day

Data had been dropping on my own (DC-HSPA+ nexus 4) and several other telecom devices all of that day.

It's better today but still mediocre


This is within a few of hundred metres line of sight to the tower as well

Speedtest.net isn't a scientific measure by any means but these numbers emulate what the real world use of the service has been like.

It'll pass when o week is over, but XT isn't as fast as it used to be. Some more 2100 in Hamilton would be nice.




Wifi via Lightwire on campus on the other hand has been pretty impressive, thanks to 5ghz wifi

Maybe the cell is under strain from all the Voice calls as well, Free on-net calling will not be helping

Is it possible to have full bars of signal showing but poor signal for data?

I was in middle of a concrete building this morning and from the same spot
0810 7+Mbps down .9 Mbps up
0940 2Mbps down .6 Mbps up
1100 .2 - .8 Mbps down .5 Mbps up

Went to george st in the open (the main st in town)
12pm 3Mbps down .8 Mbps up

Went to a street on a hill call royal terrace
12.15 .05 Mbps down .08Mbps up
This one shows full signal bars ... Maybe the data signal not as strong? Possible?

In short yes.

In long you are probably seeing a multitude of effects.

A site can only handle a certain amount of traffic (it is a shared resource), so your series in the same spot probably shows the effect of loading on the site.

A second factor is that the site is able to send data faster (using more advanced modulation) to a phone in good signalling conditions, so this may account for difference between inside and outside.  The other factor at play is noise, and both other cellsites and other handsets increase the noise, so if you are on a hill your handset may be experiencing a lot of noise, and this may cause a drop in speed even though the signal level is high.

The maximum throughput for a site will be where there are few subscribers all of whom have good signalling conditions and there are no other cellsites (on the same frequency).

The challenge for system designers is to get enough cellsites in an area to provide the coverage (including in building coverage) and throughput their customers expect while at the same time trying to ensure that the coverage of adjacent sites doesn't overlap too much (which would increase noise and reduce the throughput per cell).
