• Majority of subscribers are not located on the roads

• Complex coverage & capacity effects occur during different times of day

• Not representative of true subscriber behavior

• Ever more dynamic networks – new applications, services and devices

Traditional drive test measurements – key shortcomings

Drive test measurements do NOT reveal true subscriber experience

Importance of Real-Time for Mobile Geoanalytics

TrueCall - scalable, real-time

network monitoring is underpinned by a significant architectural foundation.

o Today’s networks and traffic demands are both extremely dynamic

o Subscriber experience is king in a world of social media

o Real-time continuous monitoring is the key enabler of next-generation networks

o A historical (non-live) approach to network monitoring alone is NOT adequate to meet these opportunities and challenges

Subscriber location intelligence

• Geomarketing with TrueCall Real-time subscriber location, direction & route of travel

Subscriber profiles based

on mobility, devices, services and other patterns

Feed geomarketing and other analytics platforms

o Data from the network is one of the greatest assets of the mobile operators – why not use it, its already there

o Intelligent correlation and enrichment of the data from different network sources enables powerful (“big data”) analytics

o Such analytics provide insight into the true subscriber experience like never before – opening up many new opportunities

o TrueCall is the 1st LTE geoanalytics solution that provides real time end to end network analytics
