Industry Challenges
Evolving mobile usage
& services driving new technologies
& challenges
Where are my demand hot spots? When &
where should I deploy
small cells?
How do I confidently
deploy VoLTE at
lower cost?
Can I get a better
window into my network?
How can I deliver a
superior VIP experience?
How can I detect &
resolve my IRAT issues?
What is the impact of a
new device?
How can I eliminate
drive testing?
What is my next best network
investment?
• 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
