LTE & Mobile Data Usage Results High Level Summary & Comments

90% of engineers need better insights on mobile data usage 95% need to better understand customer usage patterns/hotspots

! Data is driving growth, but there is a lack of information regarding how/where it is used

93% need to understand impact of own optimization efforts ! Consumer behaviour changing very rapidly, need to ensure network is robust & ready

92% need to focus effort on revenue-generating activities ! Move away from purely engineering KPIs towards business KPIs

70% of engineers expect optimization challenges in LTE 85% expect issues with hard handover affecting application QoS

! Need to focus carefully on handover zones, interference, dominance, neighbours

83% expect

problems

with

inter-RAT

handover

to

2G

&

3G

! Multi-RAT testing will be essential and drive the need for multi-channel test systems

81% foresee challenges optimizing load balancing ! Combination of complex service mixes, higher throughouts & bursty traffic patterns

73% expect issues with SON self-configuration of e.g. neighbour lists ! SON plug-and-play promises will need to be tested manually until proven and trusted

NextG Benchmarking Definition Results High Level Summary & Comments

9/10 engineers agree on attributes of future benchmarking systems 90% say a multi-processor benchmarking approach is needed to manage

the demands of high speed mobile data ! Large numbers of existing laptop-based tools will be unsuitable and need replacing

90% need a system that can go anywhere !

Portability, robustness,

independence

and

flexibility

will

be

very

important

86% need a high accuracy system to direct resources/efforts precisely ! Single drops make a difference; laptop-based tools wont provide good enough data

85% need high reliability to avoid production delays ! Systems will need to be able to offer >95% productivity levels

84% need new features to carry out indoor benchmarking ! Need to re-think the way benchmarking systems are delivered and used

75% need a multi-purpose system to do multi-channel optimization as well as benchmarking

! Need to move to more flexible, multi-purpose systems

Current Equipment Results High Level Summary & Comments

16/07/2012 SWISSQUAL AG 2000-2010 6

Conflict between future needs and current systems 77% use laptop-based tools for benchmarking today

! Laptop-based tools are becoming unsuitable and will soon need replacing

64% use optimization tool as simple benchmarking solutions ! Need to move to more flexible, multi-purpose systems for both tasks

51% use a laptop-based portable benchmarking solution today ! Inadequate for next generation with multi-RAT and high speed sensitivities 70% do not use a multi-channel portable system for benchmarking

! Large gap in current instrumentation portfolio; many operators now evaluating
