Hadoop is used to optimize the rollout of
4G coverage in time and space to
match the likely pick-up in service
revenue, allowing an operator to defer
more than 10% of capex for the same
resulting revenue.
Hadoop helped detect that only a small
number of congested cable network
nodes were responsible for the majority
of churn, and could thus be prioritized
for maintenance and upgrades.
Network function virtualization, software
defined networking and unified all IP
networks vastly increase the amount of
machine and log data relevant for
trouble shooting. Hadoop helps with
root cause analysis and may even be
used to reason on the data in real-time.

Business Problem
The consumption of services and
resulting bandwidth in a particular
neighborhood may be out of sync with a
telco’s plans to build new towers or
transmission lines in that same
neighborhood.
This leads to a mismatch between
expensive infrastructure investments
and the actual revenue from those
investments.
Examples:
4G (LTE)
FTTC (fiber to the curb)
FTTH (fiber to the home)
One European carrier used Hadoop to
optimize the rollout of 4G coverage in
time and space to match the likely pick-
up in service revenue, based on detailed
cell tower traffic data of the last few
years.
With their prior, less informed
approach, they would have had to
spend 10% more capex for the same
outcome.

Business Problem
Hadoop is used for targeted network
maintenance and upgrades by cable
companies.
One large US cable MSO was unsure
how cable network congestion affects
churn, and where exactly network
upgrades produce the most incremental
revenue.
The result was that only a small number
of nodes were responsible for the
majority of the negative customer
experience, and could therefore be
prioritized for upgrades.

Network Maintenance
– 18 –
Business Problem
Radio access networks provide the air
interface between a mobile provider and
the end user mobile devices.
Maintenance and repair of radio access
networks poses substantial logistical
challenges. In most countries, mobile
networks cover more than 95% of a
country’s surface area.
Many transmission towers are in remote
and difficult to access locations.
In high-density areas, pico- and femto-
cells optimize local coverage, but in turn
require coordination with the building
owner for maintenance.
Hadoop improves a provider’s ability to
service equipment proactively, which is
always cheaper and less disruptive than
the replacement of equipment that has
already failed.

Business Problem
Existing network management platform
meant to diagnose poor cellular service
such as dropped calls or poor audio
quality.
Overwhelmed by data volume, ingesting
10 million messages per second
Each analysis was limited to a 24-hour
time window and only one-fiftieth the
surface area of the United States.
Same customer issue may generate
multiple support calls, but the operator’s
team cannot see relationships between
multiple variables across time.
Is the problem with the customer’s
device? Is it their neighborhood or
proximity to a tower? Is it because of
how they use their phone?
With more history, they are able to
explore root causes that they have
never been able to identify by reviewing
just one day’s data, allowing them to to
improve cell phone service.

Contact center productivity

Data protection and compliance
End-user device security
With Hadoop, one operator detected
that 25% of callers were contacting the
call center merely to have their late fees
on the monthly bill waived. Clearly a
case for call deflection to interactive
voice recognition and online self-
service.
Contact center agents had insufficient
ways of diagnosing what was wrong
with customers, leading to many
unnecessary truck rolls. Hadoop
helped avoid these.
3% of smartphones account for 10-15%
of traffic because of malware (notably
on Android phones) and some fair use
violations. Hadoop helps detect that so
operators can take remedial action.

Customer Experience Analytics Based on
Call Detail Records (CDRs)
– 22 –
Business Problem
A typical mobile service provider
generates >1 billion CDRs per
day, ingesting millions of CDRs per
second.
System holds >100 billion records, half
a petabyte added every month!
Due to the cost of existing solutions, the
data expires after 60 days
CDRs need to be analyzed and archived
for compliance, billing and congestion
monitoring.
Example: forensics on dropped calls
and poor sound quality.
High volume makes pattern recognition
and root cause analysis difficult.
Often those need to happen in real-
time, with a customer waiting for
answers.
With Hadoop the carrier can to retain
some data for up to three years
Hadoop provides both a cost advantage
– Hadoop provides storage 20x cheaper
than enterprise-grade storage – and
better insights.
Better analysis to continuously improve
call quality, customer satisfaction and

Contact Center Productivity

Business Problem
A US-based mobile provider struggled
with a combination of high costs but low
customer satisfaction related to
customer care.
An increasing share of support cases
are related to mobile data usage and
associated charges.
Traditionally, contact center agents did
not have granular insights into a
particular customer’s data usage, hence
were unable to provide effective call
resolution.
With Hadoop, one operator detected
that 25% of callers were contacting the
call center merely to have their late fees
on the monthly bill waived.
The provider was able to off-load these
cases to online self-service and
interactive voice recognition.
Frees up the agents to focus on more
valuable customer interactions.
The provider is now extending this
solution to focus on issue resolution.

Business Problem
A provider’s contact center agents had
insufficient ways of diagnosing what was
wrong with customers, leading to many
unnecessary truck rolls.
In particular, the agents were not able to
triage network vs. home-based
problems accurately enough.
Therefore, technicians were dispatched
to the customer premises for problems
that reside within the network.
The provider was able to avoid a large
number of “false positive” truck rolls.
With each truck roll costing about $150
fully loaded, the provider was able to
save several million dollars already in
the first year.

Business Problem
A mobile operator needed to identify
real-time malware threats from non-

their impact on customers.
3% of smartphones account for 10-15%
of traffic because of malware (notably
on Android phones) and some fair use
violations.
Hadoop helps detect that so operators
can take remedial action, thus
eliminating a disproportionate share of
network tonnage.
Options ranged from notifying an
affected customer all the way to
blocking certain URLs for the whole
network.

customer purchases, marketing

Marketers have long sought ways to
tailor their marketing campaigns to the
needs of each individual customer.
Telcos are uniquely positioned to deliver
on that goal because mobile phones not
only follow their owners everywhere, but
also reveal a lot about their owners’
interests through browsing behavior and
the applications present on the phone.
Telcos are looking for ways to mine that
information.
Provider risked losing substantial
revenue as prepaid customers were
starting to switch to a competitor as a
result of a particularly effective
marketing campaign.
The provider used Hadoop to pinpoint
those individual customers most at risk
of churning, and then built a highly
targeted campaign to retain the
remaining customers in that segment.
A churn alarm system was established
and revenue leakage was minimized.

This data is extremely valuable for
product managers, yet much of it is out
