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!
