So here goes the start of another one of my quite possibly insane ideas ;)

Currently, im sitting on an adsl line, the 1mbit upstream is quite the contention point, with the use of the likes of dropbox hard-coded to be traffic shaped in router at this point, logically the move to vdsl would be the best bet, however That would be marginal and potentially not really work out anyway.. Depending on isp you ask, its a Yes or a No and from a 
The second part of that being, i enjoy my sub 10ms latency... DLM can be a bit of a pain with that.. (i know, im picky right!)

So, looking at alternative ideas the best option really being the fact that im covered by the Waiatarua tower thus 900mhz DC Although the Bethells tower Does seem to pop up a bit here (never knew this one had propped up, I thought the tinfoil hats down in the valley would have stopped that one like they wanted to but does explain why phone occasionally logs picking up 4G at home - I've never seen it, its always in the weee hours but apparently its there! based off details it would be 1800mhz..)

Hopefully johnR or Fraser can correct me on towers, as gist just doesn't give enough for me to calculate the realistic coverage of the bethells tower.

until 700mhz is added, i would expect its more likely that 3G would be the option for me, but that really brings me to my big questions..

Based off quick tests, 20~30/2~4mbit does not seem difficult to come by, although i know its regulated and thus expectations should be set a fair bit lower - ops there goes a ton of data for the month!


What is the RBI hardware (would be looking at having Fraser visit for the installation, thus Ultimate broadband) actually capable of? im making the assumption here that it will actually do DC-HSPA.
Secondly, is bridging possible, Without an ugly Double Natting situation(be it forwarded) on my hands - I cant get away from my pfsense build for the control it has over everything.
Lastly, What is Latency, Jitter and Upstream performance like Generally (once again, im making the assumption ild be over 3G here.)

Oh, and one final question being.. how well does it handle reasonably heavy loads (seeing 6K~8K states in a state table at peak is not uncommon - excessive, but not my personal traffic so outside of my control.)
Somewhat expect that to be a difficult one to answer as not many would see that sort of load but its worth ask anyway... 

Realistically, i know sub 10ms wont be feasible over RBI, I'm not expecting that at all. Likely i will keep at-lest an interleaving disabled dsl connection up for latency intensive traffic alone.
For the time-being, i'm ignoring the amount of Bandwidth that is actually used, That would be a bridge to cross later...

Most likely you will get 3G coverage where you are, but there are some patches of 4G lurking around you.
Typically latency on 4G RBI, e.g. to trademe is 50ms. Over 3G 70-100ms. Remember if you do those speedtests on Vodafone to Vodafone server, it is not showing full latency to outside world. Also speedtest is rather unpredictable with latency.
Latency is always variable for a data connection over a mobile network, but 4G is certainly more consistent latency than 3G.
The RBI router is a fairly basic Huawei box. There is no choice for hardware due to SIM lock, so any thing fancy with another router will mean double NAT.
Bethells tower I believe is still in RMA stage, so who knows if / when for that.
Throughput is really down to coverage strength and capacity on serving cell. We have users on 3G getting less that 5Mbps and others getting over 20Mbps. 5Mbps is the baseline for RBI. Where factors a very favourable; e.g. on my 4G RBI connection; I can get consistent 20-30Mbps transfer rate.
Upstream on 3G, tipcally 2-3Mbps, on 4G 10-30Mbps

Hope that answers a few questions.

answers a fair few, although isnt trademe a difficult one due to their pop in auckland and Wellington!

Double nat, i was somewhat expecting although hopeful it would bridge or atlest DMZ nicely.

Hopefully JohnR can fill in some details on the Bethells tower, actually didnt sit down and look at its location until now.. Just up the road actually In an interesting location. Microwave link im expecting? - AFAIK definitely no fibre runs there.


The one thing that really interested me however, is the logic behind 1800mhz rather than 700mhz, Surely the later would have been the better choice for a rural location - Although the location is quite obviously picked to be beaming down upon the valley, im likely just picking up clips off the side.

Ill go for a drive up there tomorrow and actually have a look out of pure interest.



In testing, i certainly noticed a bit of a difference in both ramp speeds and latency between Vodafone and any other Auckland based test.

thought I would add my real world migration. in the last 2 weeks I moved from a fixed line ADSL connection (6 meg down / 448 kbp up) to RBI 4G wireless. I now get speeds between 20-75 meg down and always 25+ up. an latency is about 50ms for NZ based sites. this is off a new purpose built RBI wireless tower which is good connectivity.

Having some fun getting a stable enough phone line with a cisco SPA and 2Talk but that is another story. I thought it would be sweet with the above but as I write this am I was having a play and will see how phone calls go tomorrow.

Otherwise pretty happy with the migration. didn't help the first real day I switched over Vodafone had scheduled maintenance on the tower but otherwise seems stable enough replacement for fixed line. I would highly highly recommend Ultimate Broadband, they went out of their way to help me. (reminded me of the early Snap days!)

What kind of issues?
