Domain where Hadoop can be used: TELECOM

Analyze call detail records (CDRs)

Telcos perform forensics on dropped calls and poor sound quality, but call detail records flow in at a rate of millions per second. This high volume makes pattern recognition and root cause analysis difficult, and often those need to happen in real-time, with a customer waiting for answers. Delay causes attrition and harms servicing margins.
Hortonworks DataFlow (HDF™) can ingest millions of CDRs per second into Hortonworks Data Platform, where Apache™ Storm or Apache Spark™ can process them in real-time to identify troubling patterns. HDP facilitates long-term data retention for root cause analysis, even years after the first issue. This CDR analysis can be used to continuously improve call quality, customer satisfaction and servicing margins.

Service equipment proactively

Transmission towers and their related connections form the spinal chord of a telecommunications network. Failure of a transmission tower can cause service degradation. Replacement of equipment is usually more expensive than repair. There exists an optimal schedule for maintenance: not too early, nor too late.
HDP stores unstructured, streaming, sensor data from the network. Telcos can derive optimal maintenance schedules by comparing real-time information with historical data. Machine learning algorithms can reduce both maintenance costs and service disruptions by fixing equipment before it breaks.

Rationalize infrastructure investments

Telecom marketing and capacity planning are correlated. Consumption of bandwidth and services can be out of sync with plans for new towers and transmission lines. This mismatch between infrastructure investments and the actual return on investment puts revenue at risk.
Network log data helps telcos understand service consumption in a particular state, county or neighborhood. They can then analyze network loads more intelligently (with data stretching over longer periods of time) and plan infrastructure investments with more precision and confidence.

Recommend next product to buy (NPTB)

Telecom product portfolios are complex. Many cross-sell opportunities exist for the installed customer base, and sales associates use in-person or phone conversations to guess about NPTB recommendations, with little data to support their recommendations.
HDP gives a telco the ability to make confident NPTB recommendations, based on data from all of its customers. Confident NPTB recommendations empower sales associates (or self service) and improve customer interactions. An Apache Hadoop® data lake reduces sales friction and creates NPTB competitive advantage similar to Amazon’s advantage in eCommerce.

Allocate bandwidth in real time

Certain applications hog bandwidth and can reduce service quality for others accessing the network. Network administrators cannot foresee the launch of new hyper-popular apps that cause spikes in bandwidth consumption and then slow performance. Operators must respond to bandwidth spikes quickly, to reallocate resources and maintain SLAs.
Streaming data through HDF into HDP for real-time analysis can help network operators visualize spikes in call center data and nimbly throttle bandwidth. Text-based sentiment analysis on call center notes can also help understand how these spikes impact customer experience. This insight helps maintain service quality and customer satisfaction, and also informs strategic planning to build smarter networks.

Develop new products

Mobile devices produce huge amounts of data about how, why, when and where they are used. This data is extremely valuable for product managers, but its volume and variety make it difficult to ingest, store and analyze at scale. Not all data is stored for conversion into business insight. Even the data that is stored may not be retained for its entire useful life.
Apache Hadoop can put rich product-use data in the hands of product managers, which speeds product innovation. It can capture product insight specific to local geographies and customer segments. Immediate big data feedback on product launches allows PMs to rescue failures and maximize blockbusters.
