In order to stand out from the competition and retain their subscribers, telecommunications operators are now required to know and measure the customer experience, i.e. how subscribers experience the network and their various interactions with the operator (via the contact centre, chat, email, website, social networks, etc.).

Big Data – a vehicle to improve the customer experience

In order to assess this customer experience, an operator must collect a mass of information from various sources, throughout each subscriber’s full life cycle: his/her acquisition, management, complaints, network quality, billing, requests for extra options or services, etc.

After a few weeks or months, this range of parameters will represent several TB of data to be stored. Data storage is essential to analyse changes in the information.

With conventional database systems, the storage of this information will be very costly, and it is still impossible to manage unstructured data. That is why Big Data technologies are essential to manage such large volumes of date – whether structured or unstructured – at a lower cost.
