NBN is coming… it seems

The NBN was the Australian government’s response to a dominant carrier that would not engage in government’s attempts to guide industry to develop an equitable access network beyond that delivered off the telephony copper that existed in the street (the 2007 RFP).

That ‘initiative’ sees us return the good old bad old days when government owned most of the street infrastructure used to deliver telecommunications, and of course it has been in their interest as a provider to weaken consumer controls that otherwise gave some measure of protection of service levels.

The above graph shows the performance of my ADSL broadband Internet access which reliably achieved  greater than 7Mb/s when I moved here in 2009 but fell to around 0.5Mb/s. A recent upgrade has seen around 2Mb/s fairly reliably, though not enough for reliable IPTV, a stunning improvement on the previous 3+ years. Continue reading NBN is coming… it seems

An example of Eb/N0 design with the Field strength / receive power converter

I have been asked whether the Field strength / receive power converter can be used to solve a Eb/N0 (Eb/N0) design problem.

Eb/N0 is a method often used for specifying the relationship of signal and noise that will give adequate bit error rate in a data demodulator.

Whilst the calculator was not specifically designed for that purpose, and you cannot directly enter the desired Eb/N0, with the help of a hand calculator for simple calculations, a solution can be found. Continue reading An example of Eb/N0 design with the Field strength / receive power converter

When governments tinker in telecommunications carriage…

I had cause to document broadband Internet access performance recently, an interesting exercise.

Background

When I moved into this house about five years ago, we enjoyed an excellent broadband service delivered on an ADSL1 link of about 800m to the RIM/DSLAM. The downstream rate was capped at 8Mb/s and most of the time, most of that speed was available to the end user.

For years I have run a test file transfer every half hour to document access performance, and when asked about recent performance that was an ideal source. I needed to go back to the previous week as last week started with an outage, the RIM batteries seem to have gone flat and Telstra had not been proactive in responding to the condition that left it running on batteries.

Australia’s NBN debacle limps on under a new government and new CEO

In an attempt to fix up a government orchestrated flawed regulatory and market environment that saw the dominant carrier digging its heels in to regain the right to install infrastructure that it was not required to share with competitors (ie, to allow it to reestablish a monopoly), the Labour government called for tenders from organisations to provide a National Broadband Network on its terms.

No contracts were awarded, government decided the way forward was for it to own the access network, at least for the interim, and so return to the situation that existed prior to the partial privatisation of Telstra in 1997.
