• 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”

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

• 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

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