Caveats

• LTE Networks typically have low numbers of users who are early adopters using dongles

• App Developers have not set their sights on LTE yet

• Unclear how representative current traffic mixes will be of

traffic mix in 2-3 years time

Conclusion • Continuous visibility of customer usage patterns of apps and

those apps signature on your network is key as you roll out

LTE in order to

• detect & mitigate the risk of negative impacts on the

network & revenue streams

• tailor your rollout plans

• We can’t know the future but we can monitor the present,

spot trends & take appropriate action!

Thank you!
