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

challenges !

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
