Why is quality important?
A Market Opportunity



Quality is the new focus for
competition
1/3 of mobile users have
serious concerns over network
quality (J D Power)
As many as 1 in 10 may switch
suppliers to try and find better
quality
Operators Advertising Today (UK)
Our 99.2% call success rate is the best
ever**
To ensure we give our customers the
best possible network we:
Monitor our network 24 hours a day, 365
days a year to ensure reliability and clarity
of speech
Our engineers drive 500,000 miles each
year testing the network (that's the
equivalent of driving around the world 20
times)
Recent independently-audited tests have
shown that Vodafone has the best call
success rate of all networks in the UK.
In a nutshell, it means Vodafone
customers are more likely to get through
first time and are less likely to be cut off.
That’s why we’re proud to call ourselves
the best network in Britain.
Behind The Marketing Claims

Failed new product
introductions (e.g. WAP)
Your Network Delivers Another Successful Call
“Hello?”
“Hello?”
“Hello!!”
“Can you hear me?”
“Call me back on the land line”
Getting The Right Focus

“Not everything that can be
counted counts, and not everything
that counts can be counted”

Quality Is A Moving Target

Across the network

Throughout the day

Day-to-day

Throughout the year

Impact of subscriber growth

Impact of special events

Impact of new product
launches
What are the True Measures of Network Quality?

Can I get a connection?

Do I get dropped?


Can I hear them and
can they hear me?

take to download?

Customer Experience Indicators



Customer Experience Indicators can be seen as service centric KQIs
Customer Experience Indicators can be used to set targets, KQIs to
prioritise network problems, KPIs to locate network problems
Customer Experience Indicators can be used into one of the following
report categories:

Corporate or Strategic

Sales and Marketing

Engineering & Network Operations
The Challenge

Need statistically significant quantities of measurements

Throughout the day

Across the network

Over time to see trends

Need to be able to extract “information from data”

Drive testing can deliver the measurements…but at very high cost

The Performance Analysis Mobiles (PAMs)





Small in size: 170mmx85mmx55mm, approximately
1/20th the size of traditional automated test mobile units
Only two inputs, one combined GSM/GPS
antenna and 8V-30V DC power input
Low power consumption
Reports voice quality (MOS), data
service availability, SMS, MMS and
many other standard network measurements
24/7 operation, no physical access required, test scripts
and commands are downloaded from a back-office server,
results are automatically uploaded at regular intervals
Simple Installation

