TrueNet's nationwide network of broadband probes (testing units) provides us sufficient data measurements to give reliable comment on throughput speed, i.e. the time it takes to download a file from a website such as a document or a song. The latest results for the first part of November show the "Throughput Speed" by area using data results from our test probes with full speed ADSL services.
Performance of ADSL is dependent on the distance between a user's modem and the DSLAM they are connected to.
The DSLAM (Digital Subscriber Line Access Modulator), is actually another modem at the opposite end of the copper wires connected to your house. The DSLAM equipment includes many modems, one for every user modem connected to a copper pair in the network.
There are guidelines on the "ideal" speed for any distance between the modem in a DSLAM and one in the home. TrueNet is the first to measure such performance in New Zealand, and the results are graphed below.
This article is intended to be of interest to technical specialists, more of an academic exercise for interest. We would appreciate comments.
TrueNet conducted a trial of a 5MB file downloaded to identify how long it takes before the maximum speed of a connection to be reached. The test involves downloading a file and measuring the speed of each decile (10%). The results for each tester were all over the place, some reached the maximum in the second decile, while others took until the 7th decile to reach the maximum.
TrueNet has operated its volunteer based testing service since the beginning of July 2010. The chart shows the average volunteers' speed to download a small 300KB file at 8pm each day compared with uploading the same file.
The 16th August shows an interesting change in speed.
Volunteers in this chart include some with cable, some on wireless and some who have chosen slow DSL speeds. They are however dominated by unlimited speed ADSL connections.
Early TrueNet results for Broadband speed and performance are comparable to Akamai tests reported on New Zealand connections.Analysis of Akamai Stats for NZ
Akamai has released it's "State of the Internet" report for the 1st quarter of 2010. Akamai measures download speeds from their servers located within many ISP networks which are used for frequently required files. The foremost being Microsoft and Apple updates, as well as many iTunes music files.
TrueNet, launched today, is a company dedicated to the accurate measurement and reporting of broadband performance. TrueNet is a joint venture between Catalyst IT, leading open source IT experts, and Jonette Consulting, a company specialising in broadband reporting analysis.
Computerworld (9 July 2010) reports that Graham Mitchell, the CEO of Crown Fibre Holdings is lamenting the size of sections in New Zealand. To get fibres to the home as planned, for many homes, fibre must be placed in the ground, from the road to the house, hence the problem. Innovative ways of getting them onto the ground are necessary if the project is to succeed - recall your driveway, paths, trees, fences - the underground fibre may need to go under them.
TrueNet is keen to increase the number of volunteers to our tester database. We started with friends, family and colleagues, but we are now ready to expand to enable the level of accuracy demanded for commentaries on the performance of broadband to be accurate and reliable.
Our testers will be sent a router that they simply plug into their first Ethernet socket in their network, replug all their other ethernet devices into our router, turn on and bingo tests are automatic. We can update testing remotely so no need to do anything else.
