nbn launches satellite mobility product

Proof-of-concept Wi-Fi trial with Qantas becomes commercial product

Last Friday, the company responsible for building and operating the National Broadband Network (nbn) launched its Large Commercial Passenger Aircraft (LCPA) Satellite Mobility product.

After trialing a proof-of-concept aeronautical satellite product with Qantas earlier this year, the company has released commercial supply agreements including product descriptions and pricing.

Pricing model

nbn will charge satellite mobility (LCPA) customers at a significant premium for both its access and connectivity compared with the standard NEBS (NBN Ethernet Bitstream Service) Satellite product.

On the connectivity side, the Mobility-CVC (M-CVC) will cost $2,310 per Mbps with a minimum order of 100 Mbps. This is compared to $17.50 per Mbps per month for the NEBS product plus a $200 NNI charge.

On the access component, nbn will charge $9,060 per month for each aircraft’s Mobility Beams Virtual Circuit (MB-VC).

NEBS given traffic priority

nbn states in its LCPA agreement that residential and business customers using the standard NEBS (NBN Ethernet Bitstream Service) product will be given traffic priority over satellite mobility customers.

During any capacity congestion or contention event, nbn will use a Weighted Fair Queuing algorithm to prioritise NEBS traffic over Satellite Mobility product traffic.

The agreement says that, as a result, LCPA traffic will “be adversely affected by nbn™ Ethernet (Satellite) traffic”.

Standard satellite product also revamped

The LCPA launch comes as nbn revamped its satellite offering for residential and business customers in rural and regional Australia this month. The satellite fair use policy has been relaxed with data allowances doubled across the board.

Could TPG end up partially subsidising NBN for Qantas Wi-Fi?

NBN Co placed in a potential conflict of interest under new regional broadband tax

Earlier this year, I made a submission to the Government’s consultation on the Telecommunications Reform Package.

I’ve been meaning to write a summary for some time.  I thought I’d whip one up together after it was announced that the Government planned to introduce the legislation next month despite not responding to the submissions.


As part of the reform package, the government planned to introduce a $7.09 charge per line to most fixed line “superfast” broadband services (defined as 25 Mbps download speeds or greater).

This is to help subsidise the cost of nbn’s fixed wireless and satellite networks — primarily servicing regional and remote communities around Australia.

The NBN fixed line footprint is expected to be the primary contributor of the tax.  However, other operators such as TPG with its fibre to the building network will also be hit.

NBN Co’s commercial interest

The problem is that the NBN satellite network is no longer solely about the delivery of broadband services to regional areas.

It now has other commercial interests — including the Satellite Mobility product which allows commercial entities like Qantas to tap into the satellite network for the delivery of in-flight Wi-Fi.

This could mean that a provider like TPG could be paying taxes which help subsidise the provisioning of Wi-Fi services on a Qantas aircraft.

No restrictions on subsidy for regional broadband only

The proposed bill had no restrictions that the funding must only be used to provision broadband services to regional areas — as I explained in 2.1.5 and 2.1.6 of my submission.

So, NBN Co is placed in a conflicting conundrum.  It can spend its subsidy funds on improving the quality of satellite services to regional communities like relaxing the Fair Use Policy with no additional revenue.

Alternatively, it could spend it on developing new revenue streams through commercial products like the Satellite Mobility product — competing with the likes of Optus who also have satellites in the sky.

My suggestions?

In my submission, I suggested:

  1. The Bill should make clear that the funding made available through the Regional Broadband Scheme is not available for services where the primary purpose is not to deliver broadband to regional communities.
  2. The strict Fair Use Policy (FUP) imposed by NBN Co on its Satellite network means the quality is still not directly comparable to fixed-line super-fast broadband services.As a condition of the Regional Broadband Scheme funding, the funding recipient should prioritise upgrades to the capacity and service reliability of rural and regional customers over the development of supplementary products like the Satellite Mobility product.
  3. Ensure similar protection is afforded to services delivered by means of the NBN Fixed Wireless network.

Qantas to sign trial satellite product with NBN for Wi-Fi

nbn co and Qantas set to begin a proof-of-concept agreement to test the delivery of a on-board Wi-Fi from February 2017

The company responsible for building the National Broadband Network, nbn, has released its test agreement with Qantas allowing them to test a “Proof-of-Concept Aeronautical Mobile Satellite Service” on a Qantas test aircraft.

The proof-of-concept test is expected to help guide the development of nbn’s Satellite Mobility Product expected to launch in the third quarter of 2017.

Qantas has already begun preliminary engineering testing of its proposed on-board Wi-Fi product on a Boeing 737 aircraft (VH-XZB). The national carrier intends to partner with service provider ViaSat to deliver on-board Internet connectivity once the mobility product becomes available.

The trial product will be delivered over a Layer 3 VPN connection over the NBN Satellite Network. nbn will be responsible for the network between the Air Network Interface (ANI) located on the test aircraft’s Air Terminal and the Mobility Network-Network Interface (M-NNI) located at the NBN Point of Interconnect (POI).

As part of the trial, the network speed will be limited to 20 megabits per second for each aircraft on at most two aircrafts concurrently. The connection will also be limited to agreed flight corridors.

Earlier analysis by jxeeno blog has concluded that on-board Wi-Fi products are likely to have little or no impact on the congestion of beams given the short duration of time each aircraft spends under a single beam.

The proof-of-concept agreement is set to kick in from 1st February 2017 and is expected to run until 1st September 2017 unless terminated early or extended. However, Qantas is yet to officially announce its public launch date for the on-board Wi-Fi service.

Detailed analysis: How will Qantas’ on-board Wi-Fi impact NBN satellites?

Geospatial analysis of the daily Qantas flight paths and NBN satellite beam coverage shows how NBN’s satellite network could be affected.

Writer’s note: Qantas is a customer of ViaSat, not NBN Co. ViaSat intends to trial on-board internet using NBN Co’s satellites — however, they have indicated they intend to launch their own satellites (ViaSat-3) to deliver a long-term solution for on-board Wi-Fi globally. This Qantas-ViaSat-NBN Co deal is dependent on industry consultation being completed in June 2016.

Qantas has recently announced that it plans to offer a Wi-Fi service on board its A330 and Boeing 737 fleet from early 2017 by utilising capacity on NBN’s recently launched Sky Muster satellite.  However, many Australians living in rural and regional Australia have raised concerns that the Qantas service will cause further congestion on an already limited service.

The company responsible for building the National Broadband Network, nbn, had completed a review of satellite capacity in its Fixed Wireless and Satellite review where it identified 31 beams around Australia that would be oversubscribed or severely oversubscribed once a take-up rate of 65% is reached.  As a result, the company will introduce strict Fair Use policies to significantly limit the amount of data to 150 GB (priced at a premium) that can be used by each customer on a 4-week rolling average basis.

Consequently, the Qantas announcement has infuriated many who are within the satellite footprint.  Analysis of flight paths taken by Qantas’ domestic flights using their A330-200, A330-300 and Boeing 737-800 fleets show that all planes fly through at least one congested or severely congested satellite beam.

Key findings:

  • 334 Qantas domestic flights utilise the A330-200, A330-300 and Boeing 737-800 fleet on the day analysed.
  • Every flight flew under at least one oversubscribed or severely oversubscribed beam.
  • 58% of oversubscribed or severely oversubscribed beams will have minimal impact, with at most 2 planes flying under the beam at any given time.
  • The Sydney-Brisbane and Sydney-Gold Coast routes travel entirely within severely oversubscribed NBN Satellite beams (34, 29, 25, 20).
  • The Sydney-Melbourne, Melbourne-Canberra, Sydney-Canberra and Townsville-Brisbane routes travel entirely within oversubscribed OR severely oversubscribed NBN Satellite beams.

Analysis: by congested beams

Over half (58%) of congested beams are not affected or are minimally affected by Qantas planes.  Of the 31 beams considered oversubscribed or severely oversubscribed, 5 of them do not cover any current eligible Qantas flight paths.  7 beams will have at least one flight under the path at some point, and 6 beams will have up to 2 flights under it at the same time (within a 10 minute time frame).

Unsurprisingly however, the beams covering areas immediately surrounding capital cities will have the greatest number of flights under it at any given time:

  • Beam 42 (Sydney Beam) is the worst affected, with up to 7 Qantas flights within a 10 minute time frame travelling under it.
  • Beams 47 (Melbourne Beam) and 20 (Brisbane Beam) come in second, with up to 6 Qantas flights within a 10 minute time frame travelling directly under each of them.
  • Beam 37 (Adelaide Beam) comes in third, with up to 5 Qantas flights within a 10 minute time frame travelling directly under each of them.

It should be noted though, that for the day analysed — the Sydney and Brisbane beams only had the greatest number of flights under it for a single 10 minute time frame (between 8:50am – 9:00am and 7:30pm – 7:40pm respectively).

Finally, by considering the average number of Qantas planes under a beam over a 24 hour period — we see that Beam 47 (Melbourne) tops out at 1.94 planes with Beam 42 (Sydney), Beam 20 (Brisbane) and Beam 41 (Canberra) following closely behind at 1.52, 1.45 and 1.22 planes respectively.

Analysis: by flight

Each flight and its flight path were analysed to see which NBN Satellite beam it flies under. The results shows that every single Domestic Qantas A330 and B737 flight flies under at least one oversubscribed or severely oversubscribed satellite beam.

The most prominent are the Sydney-Brisbane and Sydney-Gold Coast routes, which flies entirely within severely oversubscribed beams (that’s beams 34, 29, 25, 20).  Sydney-Melbourne, Melbourne-Canberra, Sydney-Canberra and Townsville-Brisbane routes fly entirely through oversubscribed or severely oversubscribed beams.

Concluding thoughts…

I find the results of this analysis somewhat inconclusive. Firstly, unlike domestic US services — the number of Qantas flights expected to get the Wi-Fi service is quite small.

With under 350 flights spread out geographically and over a 24 hour period, I doubt the planes would have a material effect on congestion. Currently, the worst case scenario seems to be up 6-7 planes flying under a single beam at any given time. However, in the case of the 7-plane statistic, it happens only once in a 24 hour period. The speed at which planes travel also mean that they will typically fly in and out of narrow beams within 10-15 minutes, meaning any impact should be distributed across multiple beams as the plane flies through the airspace.

On the other hand, the bulk of the flights will fly under already oversubscribed areas. This is especially true for the beams serving the areas immediately surrounding the capital cities, which are all severely oversubscribed (bar-Darwin). These areas also have the greatest number of concurrent flights, represented by the “average number of planes over 24 hours” statistic.

So, no. I don’t think there’s an immediate threat to congestion. However, it does set a precedent. If more carriers get on board… and if international flights get added to the pool as well — things could well change in the future.

Assumptions made in this analysis:

  • The flight data analysed was from Wednesday, 23rd Feb 2016.
  • Qantas will only install the Satellite-powered Wi-Fi solution on their A330-200, A330-300 and Boeing 737-800 fleet.
  • In all cases where the plane transverses an area with both a wide and narrow beam, the congested, narrow beam is selected.
  • Plane locations are calculated in 10 minute intervals.
  • Congestion (oversubscribed beams) are based on results in the NBN Fixed Wireless and Satellite Review.
