“Maybe along with the three legs that 5G stands on (massive Machine Type Communication (MTC), enhanced Mobile Broadband (eMBB), and Ultra Reliable Communication (URC)) we need to add a fourth leg of ultra low cost broadband (ULCBB).”

Customers and Operations are key

Customer Experience (CEX)• Do we really know our 

Customers? What do they LOVE?• Knowing my name does not mean 

you know me.• How do we make the experience 

more Personalised?• What is the competition doing in 

this space? OTT vs Telco

Organisational TransformationData Revenue per Connection is not a viable Business CaseHow do we add value by introducing Analytics?What should we do to best manage NFV & SDN?
