LTE rol lout moves towards citiesPrimary LTE focus in rural areas missing broadband coverage, move now to
urban areas
Challenges in Small Cell Deployment Vodafone Germany, Networks3
Phase 1
Cover “ white spots” in rural areas
Phase 2
Higher bandwidth and better coverage
in urban areas
LTE / HSDPA - Top speed (indoor )
LTE coverage rollout in urban areas will increase deployment

Further increase of data traffic with LTE introductionLTE data traffic add up to approx. quarter to complete mobile network data traffic
Challenges in Small Cell Deployment Vodafone Germany, Networks5
One year after LTE network
launch the LTE data traffic
volume is higher than
UMTS traffic volume during
the first six years.
LTE rol lout in urban areas will increase capacity demand !

Challenges in Small Cell Deployment
Challenges in Small Cell Deployment Vodafone Germany, Networks8
Regulatory and legal aspects for small cell locations have to be
considered. Site infrastructure, power supply and backhauling have to be solved
Interworking with existing network layer is mandatory
A heterogeneous network structure needs sophisticated methods
for planning optimisation and operation
Invest & operational costs are key criteria
We need innovative solutions to enhance our network
and improve customer satisfaction
