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

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?

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…
