Rural Broadband no match for Urban Areas
However RBI funded Rural upgrades are delivering the goods
TrueNet's quarterly Rural Broadband report shows a big mismatch between rural and urban areas. In November, Panelists
with Rural ADSL took twice as long to load our group of Live Webpages compared to Urban ADSL Panelists.
The government's Rural Broadband Initiative is slowly reducing this difference by funding upgrades to rural copper
services with minimum speed targets of 86% getting 5Mb/s or more.
Summary of Performance Measures
The 9pm speed of services other than ADSL were typically slower this month, e.g. VDSL average down to 21 Mb/s from
23Mb/s last month, high speed cable and 100M fibre services also lower.
In contrast, 50Mb/s upload speeds increased during the month with Snap 50Mb/s service averaging 53Mb/s UP in November.
In our quarterly feature, we continue to watch the state of Rural Broadband. Panelists with Rural ADSL take about twice
as long to load our group of Live Webpages compared to Urban ADSL Panelists. Sharp reductions in speed during the
evening busy hours have a significant effect on rural broadband performance. However, ADSL funded by the governments RBI
(Rural Broadband Initiative) perform much closer to urban speeds.
After several months of reporting, iiNet is no longer ranked last in our test of Australian Live Webpages.
Webpage Download time
Slow webpage downloads can be one of the most frustrating experiences when using the Internet.
TrueNet uses a selection of Live NZ and Australian internet Webpages to measure performance, downloading them the same way as a standard computer. The choice of pages was updated on the
1st of November, adding a new Australian located page and new New Zealand Webpage.
NZ Live Webpages
Comparing all technologies, Orcon 100Mb/s Fibre remains quickest overall, downloading the NZ Live Webpages in 1.8seconds. Rural ADSL is slowest, downloading in
12.2 seconds.
TrueNet now has sufficient Vodafone and Spark Panelists to include in the November Fibre results. Vodafone 100Mb/s(downloading in 2.3 seconds) lags behind all other fibre products except for Snap 10/30Mb/s (downloading in 2.4 seconds)
Competition is hotting up in the VDSL market with Vodafone back on top, closely followed by Orcon and Snap.
Slingshot, Flip, Bigpipe, and Orcon are evenly matched, and lead ADSL as a group, with iiNet taking the longest to load the live pages.
Australian Live Webpages
Comparing all technologies, Snap is best for 100Mb/s Fibre service, and is also best for 30Mb/s Fibre.
Vodafone again leads the VDSL providers, Flip the ADSL.
iiNet ADSL has gone from last place in October to 4th in November through the deterioration in performance of the other ADSL
providers, Spark, Vodafone and Snap
Speed (File Download Performance)
For TrueNet's speed tests each panelist's probe regularly downloads a 1MB file from Auckland, Wellington, Dallas and
Sydney.
For national tests the median of the best Auckland or Wellington download speed result is used from each test run.
International tests represent the median hourly speed of each probe to Dallas & Sydney.
International File Download Speed
TrueNet has servers in Sydney and Dallas to measure performance from our international neighbours.
This test provides a comparison that can be used to understand the performance of each ISP when downloading a sample
file from servers in similar locations. We ensure the file is not held in New Zealand (cached) so that the test is
international in nature. The speed test results selected are taken at 9PM, in the evening busy period.
In Chart 3, Orcon 100Mb/s Fibre is fastest to Sydney ; last month Snap 100Mb/s Fibre was almost equal, but has dropped back again. Vodafone 100Mb/s Fibre, and 10/130Mb/s Cable are well below their advertised speed
NZ File Download Speed
Comparing performance by time-of-day is important as it shows the service degradation when everyone is using the
internet during the peak hours of 8pm to 10pm.
Fibre - Cable - VDSL Comparison
Fibre testing measures the best of Auckland and Wellington downloads. Fibre advertised speeds are limited by the supply
from some LFC's that provide 100Mb/s wholesale, which can only ever reach about 95Mb/s retail. Some LFCs are now
offering connections at 106Mb/s wholesale to overcome this limitation.
There are enough Panelists to include Spark and Vodafone in Fibre results this month. In Chart 5, Vodafone 100Mb/s Fibre lags well below its advertised speed achieving only
35Mb/s at 9PM.
Snap is ahead of Orcon this month in the 100Mb/s services. Vodafone's 130Mb/s cable service remains fastest overall, though the 9PM speed is
similar to fibre.
Results for all three 30Mb/s Fibre providers are very similar though Spark's service shows a reduction in the evening
busy period.
The number of fibre service product plans offered is increasing, making it difficult to have enough panelists in each
plan to compare. Down stream speeds now include 30Mb/s, 50Mb/s, 100Mb/s and 200Mb/s. In Chart 6 below, the ISP Fibre
speeds relative to the Advertised Service speed is shown, giving an indication of ISP performance across the different
plans. This method enables more Panelist results to be included, hence Vodafone results include some 30Mb/s connections.
Orcon and Snap performance is quite close, as has been reported over many months. Spark and Vodafone are achieving
somewhat less at the present time.
TrueNet has observed that as ISPs offer UFB Fibre services, there are problems at the start up of Fibre services that
result in lower speed performance. These are subsequently sorted out, and we observe improving results. Vodafone appears
to be a special case, with several panelists experiencing very slow ramp-up, such that results for 1MB, as well as our
check files of 5MB and 7MB do not approach full speed.
DSL Performance by Time of Day (ToD)
VDSL & ADSL testing is also based on the best of Auckland & Wellington downloads, as described above. DSL speed is strongly related to the length of the copper line between the
user's modem, and the cabinet or Exchange.
VDSL File Download Speed
Orcon and Vodafone had solid results this month, staying above 95% throughout the month. Spark and Slingshot results are noticeably impacted in the evening hours, with Slingshot's November performance (90%) down on last month
(95%).
ADSL File Download Speed
Chart 8: Bigpipe and Flip achieved excellent results this month, along with four other ISPs achieving better than 95%. Slingshot and Vodafone dipped below the 95% mark in the evening. Interestingly, although Spark VDSL dips between 8pm and 9pm, the ADSL results are better, and have improved on last month (October - 93%, November -
96%).
Upload Speed Performance
Upload speed is important when sending files and content to the internet. Upload speed impacts the time taken to upload
a photo or synchronise data with the cloud.
TrueNet's upload test sends a 1MB file to our server in Wellington, and records the results using a similar method to
the download tests, but measured from our Wellington server only. We test Australian connections to Sydney.
By Technology
There are small changes in Fibre upload results this month. 50Mb/s Fibre speed average was up to around 44%. The 20Mb/s
service averages dropped from above 20Mb/s, to just under. Fibre and Cable 10Mb/s services achieved very similar
results, with VDSL lagging behind.
Upload Speed by ISP
An Upload speed comparison between Fibre and Cable providers is shown in Chart 10. Snap's 50Mb/s service increased beyond the advertised speed to average 53 Mb/s this month, and Orcon's average also increased to 44 Mb/s.
Amongst the 10Mb/s Upload services, the results are virtually identical.
Vodafone fibre upload missed the cut for sample size becasue they have a mix of 20 and 50Mb/s upload options for 100Mb/s
download, which reduced the sample sizes.
Quarterly Feature - Rural Broadband Performance
The Rural Broadband Initiative (RBI) is demonstrating it's value. RBI funded ADSL connections served by "Other" ISPs (Slingshot, Vodafone & Xnet) had fantastic results, equal to Urban ADSL connections. See Chart 12.
Pre-RBI Rural ADSL broadband generally lags well behind services in Urban areas. The Rural Broadband Iniatitive (RBI) is
a Government project to upgrade this older rural equipment to match that of the urban network.
Our Rural Panelists are mainly on ADSL, with long copper lines, or more recently installed RBI (Rural Broadband
Initiative) funded ADSL. We have a limited number of Wireless Panelists, but are keen to publish comparitive results as
soon as there are enough probes on Wireless services.
Webpage Downloads
The total time to load the Australian and New Zealand live Webpages is shown in Chart 11. Note that Rural ADSL takes
over twice as long as Urban ADSL to load this set of Webpages. Whereas, the RBI-funded ADSL performance is close to that
of the Urban ADSL average.
Rural File Download Performance
The number of Rural Panelists is limited, but there are now sufficient Panelists for reporting individual ISPs. In Chart
12 below, Snap and Vodafone each have enough probes to report statistically accurate results. We group related brands together to enable us to
report on Spark (Spark & Bigpipe) and CallPlus (Slinghot, Orcon & Flip) rural connections.
Rural ADSL (Pre-RBI) - solid lines
Chart 12 shows that Rural ADSL Panelists experience a significant speed reduction in the evening busy period. The CallPlusgroup is the best of the rural ADSL providers shown. Snap and Vodafone have very similar results in our first Rural ISP
Comparison. The Spark group has the biggest variation between peak and off-peak speeds.
Rural RBI ADSL - Dashed lines
In Chart 12, ADSL funded by the Rural Rural Broadband Initiative, see "RBI Other" - Slingshot, Vodafone & Xnet, can be as good as Urban ADSL (Chart 8). Spark is the exception, but we understand an issue of DNS overloading on Spark was resolved last week, which should see this
problem improve.

Backhaul or Longhaul - the links that are used to connect over long distances, eg from say Christchurch or Hamilton to Auckland.
ADSL, VDSL, DSL - the standard broadband service provided over a telephone line from an exchange or a cabinet (FTTN), VDSL is a faster
version than ADSL. They use similar technology and backhaul, so sometimes DSL is used when referring to both.
Capped Plans - the most common ADSL service, where you have a monthly plan having a GigaByte (GB) limit of usage each month before
your speed is slowed or you must pay more.
Unlimited Plans - ADSL service where there is no monthly limit on the amount of data used. Specifications for this service include that
it may be "Managed" and have "performance reductions applied during peak demand periods."
Cable - Cable is offered by Telstra & Optus in Australia, and is available in a limited number of cities. Vodafone offers cable in the Wellington and
Christchurch areas.
Cabinet - In NZ there are two cabinet types, an Active Cabinet, which has electrnics inside, usually a DSLAM, and a Passive
Cabinet, which is simply a flexible cable joint. They are common in suburbs as large steel cabinets with usually two
doors for accessing the insides. Chorus is often having them painted with pictures to reduce graffiti.
DNS - Domain Name Server. As the Internet is based on IP addresses, a DNS service translates domain names into the
corresponding IP addresses.
DSLAM - the exchange or cabinet based equipment that your modem is connected to, over the pair of copper wires that are
exclusively allocated to your premises.
Ethernet - The wiring used to connect computers to a network, typically an Ethernet cable is coloured (often blue), with small
square connectors at each end.
FTTN - Fibre To The Node is based on fibre-optic cables run to a cabinet serving a neighborhood. It uses existing coaxial or
twisted-pair infrastructure to provide connections from the cabinet to the home. Approximately 50% of NZ homes are able
to be served by FTTN
FTTH - Fibre To The Home (or Premises) are connected using a gigabit passive optical network (GPON). A fibre cable, known as
the "drop fibre", goes from the premises to the street. The "drop fibre" cable joins a "local network" which links a
number of premises to a splitter in the fibre distribution hub. In NZ this is known as UFB.
ISPs - Internet Service Providers. TrueNet has probes measuring almost 20 ISPs but only reports on those where there are 5
or more probes working during any particular month.
Latency - The time for a packet of data to be returned by a remote server to the probe when a "Ping" command is issued. TrueNet
sets targets for maximum median latency that are known to be achievable. The roundtrip Latency between Auckland and
Dunedin in fibre optic cables is roughly 15 msec.
LFC - Local Fibre Company. These companies are rolling out FTTH connections subsidised by the government, but must sell
services through ISPs.
LLU - or Local Loop Unbundled lines are DSL lines where the ISP uses their own DSLAM in the exchange to deliver DSL
services. The ISP then leases the copper line (Local Loop) between the exchange and their customer's premises.
Median - The Median is found for each probe and this is input to any analysis to calulate the average performance. This means
that any result represents the “middle” performance measure applicable for that probe. Using median ensures that the
result is more representative due to the often skewed nature of measurements by probe.
NBN Fibre (AUS) - "NBN co is a single entity rolling out fibre nationwide and then wholesaling it to ISP’s" from a good comparison here.
Speed - Throughput or the median peak connection speed achieved during our standard test downloading an image from our test
servers. TrueNet normally reports speed as a comparison at low vs high demand times to show any capacity constraints
evident in speed performance, often called the Time of Day analysis.
UFB Fibre (NZ) - Ultra Fast Broadband connections are the service offered by some ISPs over the Fibre to the Home (FTTH) network built
by LFCs over government subsidised fibres. Services now being offered include 100Mbps, 50Mbps and 30Mbps, with 200Mbs
expected in the near future.
Webpage Download - TrueNet maintains a Standard Test page which is used for measuring the time to download the entire page. This page is
visible here, we use a copy located on our test servers for test downloads. The time to download excludes the time for a
browser to generate the page on a screen, some are faster than others.
