• Cost Effective High-Speed Broadband Soon -- 2 objectives that can be compatible
– Objective 1: Encourage/Invest in infrastructure wisely• Smart-Managed Vectored VDSL
– Objective 2: Encourage Innovations/Apps for consumers/business• Software Unbundling, or “Software-Defined Access Network”
Smart Australian NBN Investment

How Much Fiber?more = more costmax speed for 1km of copper
What about the untethered consumers?

Vectoring’s major issue: other noises
• Crosstalk removal “exposes” other noises– Need management of stability
Noise A
NoiseB
Noise CNoisefloor
Vectoring does not cancel A,B,Cbecause they are not at transmitAntenna location (only at receiver)
Crosstalk noise

Such Management Does Matter !

Wi-Fi Management
10
• Investment is $100’s for 100’s Mbps
• Smart Management is essential and crucial
– No box by itself is going to solve this problem.
100 Mbps NBN can be very Cost-Effective

4 out of 10 customers QOE is limited due to Wi-Fi (Europe)
50% of problems are Wi-Fi related when DSL < 10 Mbps>>50% even with FTTH solutions, so investment value reduced

• Orange Fiber – my house, Paris, Oct 20, 18:45
– Why? All my neighbors are on the PON now – I wanted to watch OTT video – Football match (doesn’t
work)
• My old DSL always ran > 6Mpbs!!!
AND, Fiber is SLOWER than DSL
17
Next morning, 07:05, no one using?
• But the game was over ……• Give me back my old faster DSL please.

Wi-Fi offload (to fixed) dominates mobile
Tablet Growth = Faster than SmartphonesiPad = ~3x iPhone Growth

• Software version of owning the hardware– Differentiate all the way down to physical level– Software management of connection speed/stability
