Expected Change - Mobility Dominates !!
70% Of Total Telecom Users Are Projected To Be Wireless By 2010
Source: ARC Group, 2004
Asia-Pacific: a region of superlatives!!
Average annual mobile growth over the last five years is close to 30 per cent
By early 2008, number of telephone subscribers had passed the 2 billion mark
Mobile penetration approaching 40 %
2 out of 5 inhabitants in the region enjoy benefits of mobile telephony today

What continues to be the Challenge
Entry into new markets/revenue enhancement
Increased subscriber confidence
Multi-vendor capability - optimize, secure & manage multi-vendor network
Subscribers demanding more advanced capabilities from operators
Wireless technology continues to evolve & become more complex
Change Drivers for Telecom Operators
Revenue Growth Rate – 2 to 3 times:
Increasing pressure on productivity
Industry pressures:
Increase rate of new service introduction
Complexity of new services, service models & technology insertion:Increasing costs, lowering customer satisfaction
Ongoing need for revenue & margin growth
ARPU erosion: Increasing pressure on margins
Impact of Network Performance on subscribers
Network Quality
Consistent Coverage
Network Availability

Top 3 reasons for subscriber churn
Dropped Calls
Poor Service Quality
Limited Coverage
Decreased Satisfaction

Traditional network planning and Optimisation techniques
Simulation based
Based on “prediction” of coverage
In-building coverage planned on “assumed” penetration losses
New-site selection based on subjective data
Optimization based on very small samples and aggregated data
Based on simulations and extrapolations
� Percentage of time Physical Channels are available for use
� Affected by -
– Faulty base station equipment,
– Bad transmission links or
– Wrong configuration definition at the switch
� Advised threshold for acceptable performance is 99.00%
� Ability for a call to stay connected
� Affected by -
– Poor coverage,
– Poor RX quality or
– High timing advance
� Indicative of -
– Large cell radius,
– Non-optimum cell parameter settings,
– Poor frequency/BSIC planning or
– Faulty base station equipment
� Advised threshold for acceptable performance is 2.00%
� Percentage of time a user is rejected due to the unavailability of system
resources when attempting to place a call
� Can be due to -
� Inadequate traffic resources like TRXs or cabinets, seasonal
sporadic surges
� Improper RF feature parameter settings or
� Problems in the neighboring cell
� Advised threshold for acceptable performance is 2.00%
� Percentage of calls dropped due to bad quality
� Affected by
– Poor RX quality caused by poor frequency/BSIC planning, faulty
equipment/time slots
– External interference sources or
– Non-optimum parameter settings
� Advised threshold for acceptable performance is 10.00%

While all these techniques were good, did they:
� All subscribers
� All over the network
� At all times
� Including all in-building?
Identify opportunities for network improvements based on actual subscriber usage of the network?
Show how the network is actually experienced by:

Imperatives for Outsourcing
Finding & retaining qualified staff who manage complex network; a huge challenge
Subscriber loyalty is affected by poor quality of service
Increasing competition necessitates service
differentiation
Network size & complexity is rapidly increasing with new multi – vendor, technology & version networks becoming increasingly common
Subscriber’s expectations are increasing, but the cost of managing the network must be reduced
Doing it the Old way……Leads to
� Separate RF teams, requiring
regular investment in training and
expensive retention plans
� Costly PM and CM tools for
planning and optimisation
� Upgradation cost of tools, new
tools in the market
Each operator investing in its own
Duplication of efforts, synchronization
issues among teams
� Painful ramp downs after
completion
Temporary ramp ups required during
peak phase and
What is needed is…
� Pool of highly experienced RF
experts to handle complex RF
challenges
� Diverse range of tools that serve
multiple technologies & network
needs
� Ability to apply learning of similar
problems in other markets to
shorten time delay to resolve
� KPI related “outcome based
projects”
� A shift from individual excellence
related assignments
Cost effective, timely and
adequate
changed the rules of the Game…
