3 Berlin, 9 April 2013

Introduction

• The European Union is committed to an

ambitious Digital Agenda for Europe (DAE).

• The DAE includes

- full broadband availability in 2013,

- 100% availability of 30 Mbps in 2020, and - 50% adoption of 100 Mbps by 2020.

• It is widely acknowledged that meeting these

goals is challenging.

(4)

4 Berlin, 9 April 2013

Introduction

• What is really meant by 30 or 100 Mbps?

• Requirements for speed and symmetry

should be understood in light of the use that consumers are likely to make of the network.

• What trends are visible as regards:

- Applications in use?

- Bandwidth demand per HH?

- Traffic asymmetry?

• Demand is dynamic over time.

(5)

5 Berlin, 9 April 2013

Introduction

• DAE was initially viewed in an FTTx-centric way.

• Commissioner Kroes, Barcelona, 27 February:

“I also want at least half of Europeans to have ultra- fast access at over 100 Megabits by 2020: again, it is clear that no single technology will deliver this, no

single magic potion will get us there overnight. We rather need an intelligent mix of complementary

technologies, deployed incrementally, and according to local circumstances. Such technologies include in particular Fibre-to-the-Home, upgraded Cable, Fibre- to-the-Cabinet and LTE.”

Coverage and capabilities

7 Berlin, 9 April 2013

Basic broadband coverage

• For years, European broadband policy was based on flawed coverage data.

- Assumed full coverage of the fixed network, which clearly was not the case in newer Member States.

- Assumed that all fixed network lines were good enough to support broadband.

• A 2012 Point Topic report for the European

Commission provide an improved baseline.

Coverage in Europe

• Basic broadband

- The older Member States have nearly full coverage.

- Some of the newer Member States have sufficient gaps in rural coverage.

• NGA coverage

- Member States with cable already enjoy full deployment (the Netherlands, Belgium, Malta).

- Some eastern Member States have already deployed substantial fibre.

- Some eastern Member States have lots of cable.

(11)

11 Berlin, 9 April 2013

Coverage of Cable Networks

• Total cable coverage in Europe is substantial.

• A significant fraction of this cable

infrastructure is DOCSIS 3.0 capable.

• The remainder could be upgraded at modest cost.

• In many Member States, cable represents

a significant fraction of total broadband.

22 Berlin, 9 April 2013

Implications for network design

• Average busy hour traffic (which largely drives the size of the network) per user is much lower than many assume, and is likely to remain far less than DAE access speeds.

• This suggests that media with shared bandwidth – wireless and cable – are likely to be able to meet consumer demand well into the future.

• High access speeds nonetheless offer benefits.

- Enable applications that would not otherwise be possible.

- Faster response from all applications.

(23)

23 Berlin, 9 April 2013

Does supply drive demand?

• It is fairly clear that demand for broadband can drive supply.

• How does supply affect demand?

• Will abundant supply stimulate creation of new bandwidth-hungry applications?

• Alternative hypothesis:

- too little available bandwidth can reduce consumption, but

- “too much” bandwidth availability has only limited ability to promote bandwidth consumption.

Global Internet traffic trends

“[M]ost forms of Internet video do not have a

large upstream component. As a result, traffic is not becoming more symmetric as many expected when user-generated content first became

popular. [S]ubscribers still consume far more video than they produce.”

Cable Technology

(29)

29 Berlin, 9 April 2013

Technical capabilities of cable

• The (inexpensive) upgrade to DOCSIS 3.0 enables high speed cable broadband.

• Cable is a shared medium; nonetheless, cable operators have considerable control over the bandwidth available per user.

- More CMTS can be deployed to serve a group of users.

- More fibre nodes can be deployed to a street cabinet.

- If a cable system has been deployed with excess fibre capacity, these upgrades need not require civil works.

• These upgrades can be made incrementally.

31 Berlin, 9 April 2013

Technical capabilities of cable

• Cable systems could offer symmetric bandwidth if there were customer demand for it.

• Current channel allocations on cable systems provide far more bandwidth downstream

(e.g. 5 MHz to 65 MHz) in order to enable more linear video to consumers.

• There could however be a different allocation if there were a business case to do so.

• If consumer demand for symmetric broadband services were to grow, cable could readily adapt.

• Policymakers may prefer to promote facilities-based competition, rather than cost savings for a single infrastructure.

• This example reflects Spain as it was in 2010.

(39)

39 Berlin, 9 April 2013

Concluding remarks

• A technologically neutral approach to the DAE, drawing on cable and LTE, offers real benefits.

• Cable can and does serve as

- an alternative to making FTTx upgrades, especially in areas where the cost of fibre upgrades would be

particularly uneconomic, providing cost savings; or - as a second fixed network in a given area, providing a

facilities-based fixed network alternative to an FTTx network, thus enhancing competition.
