Solving the 10% The Governments objective for NBN Co is: • A minimum fibre coverage obligation of 90 per cent of Australian premises. • All remaining premises will be served by a combination of next generation fixed wireless and satellite technologies – providing peak speeds of at least 12 megabits per second. – Copper retained for telephony option2 © NBN Co Limited 2012

Challenges General • Delivering the most cost-effective technology mix • Take-up and usage estimates • Explaining technology rollout requirements to users Technical • Spectrum is a scarce resource • Spectral efficiency is approaching its limits • We cannot always place wireless towers in the ideal location • GNAF and cadastral data has its limitations4 © NBN Co Limited 2012

Advantage of Packet Networks – statistical multiplexing • The common pathways (eg. CVCs) have less capacity than the total capacity that users could try and use. • The behaviour of any individual end-user is unpredictable • But as traffic gets aggregated, capacity utilisation becomes more predictable100% Average aggregate utilisation per 30 minute time period90%80%70%60%50%40% ACCESS VC CONNECTIVITY30% VCs20% Fibre10% Access 0% Node 14:00 16:00 18:00 20:00 22:00 0:00 2:00 4:00 6:00 8:00 10:00 12:00100% Average aggregate utilisation per 30 minute time period90%80%70%60%50% Ethernet40%30% Aggregation POI Switch20%10% 0% 14:00 16:00 18:00 20:00 22:00 0:00 2:00 4:00 6:00 8:00 10:00 12:00100% Average aggregate utilisation per 30 minute time period90%80%70%60%50%40%30%20% 100%10% Average aggregate utilisation per 30 minute time period 90% 0% 14:00 16:00 18:00 20:00 22:00 0:00 2:00 4:00 6:00 8:00 10:00 12:00 80% 70% End User Traffic 60% 50% 40% 30% 20% Aggregation Network Traffic 10% 0% 14:00 16:00 18:00 20:00 22:00 0:00 2:00 4:00 6:00 8:00 10:00 12:00 Access Network Traffic 5 © NBN Co Limited 2012

How capacity planning benefits NBN Co• The equipment in our network is designed to make use of statistical multiplexing• Large Scale Network Capacity Planning rule: 1Mbps = ~200GB / month• A fixed customer base per access node (eg. wireless cell, satellite beam) permits deterministic capacity per end-user• Eg. Satellite spot beam with 300Mbps of capacity over 1000 end-users = 300kbps of capacity per end-user 300kbps ≠ expected throughput per end-user. 300kbps supports average downloads of 60 – 70GByte / month. 6 © NBN Co Limited 2012
