To be in the cutting-edge of business and technology, a company like Telefónica needs to be constantly looking beyond its telco boundary, to be updated in the latest tech discoveries. It needs to be close to what’s happening in the scientific community around the world, and to have a way to advance the state of the art, positioning Telefónica as a pioneer of the tech world. 


Telefónica Research was created for this purpose. Under the strong and lasting tradition of R&that Telefónica has had for over 30 years, the Research team in Telefónica pushes the boundaries of fundamental science and technology, sharing their knowledge within the international community, thus placing Telefónica in the forefront of scientific research. 


Telefónica Research includes a diverse, multidisciplinary and international group of scientists who dare to explore the edges of knowledge, without losing the purpose of adding value to Telefónica’s business. The balance between the aim to explore and discover, the focus on nurturing the company and staying close to the business is one of the things that makes Telefónica Research one of the most unique and valuable assets of Telefónica.  


The place the Research team has earned within the international scientific community as one of the top players of the academic research world is one of the guarantees Telefónica has of leading the technological revolution that will take us to the more  human, more connected future we want.

These are the EU funded projects the research team is taking part on:


ACCORDION (2020-2022): ACCORDION establishes an opportunistic approach in bringing together edge resource/infrastructures (public clouds, on-premise infrastructures, telco resources, even end-devices) in pools defined in terms of latency, that can support NextGen application requirements. To mitigate the expectation that these pools will be “sparse”, providing low availability guarantees, ACCORDION will intelligently orchestrate the compute & network continuum formed between edge and public clouds, using the latter as a capacitor. Deployment decisions will be taken also based on privacy, security, cost, time and resource type criteria. 


PIMCity - Building the next generation personal data platforms (2019-2021) Personal Information Management Systems (PIMS) aim to give users back control over their data, while creating transparency in the market. However, so far, they have failed to reach business maturity and sizeable user bases. PIMCity offers tools to change this scenario by: 1) implementing a PIMS development kit (PDK) to commoditize the complexity of creating PIMS, which will lower the barriers for companies and SME to enter the web data market; 2) designing and deploying novel mechanisms to increase users’ awareness; 3) demonstrating the effectiveness of the above tools by engineering EasyPIMS, the fully-fledged PIMS of PIMCITY.


DICE: Dynamic Interconnections for the Cellular Ecosystem (2019-2021) The DICE project is an H2020 Marie Curie Individual Fellowship, supporting the work of Andra Lutu on interconnection in the mobile ecosystem. Andra will work on proposing new solutions for dynamics interconnections between cellular operators world-wide, while also studying the current ecosystem and designing solutions to improve the experience of cellular users roaming internationally. 


CONCORDIA: Cybersecurity Competence Network for Research and Innovation (2019-2023) A Cybersecurity Competence Network with leading research, technology, industrial and public competences. CONCORDIA provides excellence and leadership in technology, processes and services to establish an user-centric EU-integrated cyber security ecosystem for digital sovereignty in Europe.  


INCOGNITO: Identity verification with privacy-preserving credentIals for anonymous access to online services (2019-2023) The overarching goal of INCOGNITO is to combine state-of-the-art technologies in a platform that will allow users to easily understand what is needed to access online services with respect to their privacy and be able to prove specific attributes of their identity or their whole identity.


I-BiDaaS (2018-2020) I-BiDaaS aims to empower users to easily utilize and interact with big data technologies, by designing, building, and demonstrating, an unified solution that: significantly increases the speed of data analysis while coping with the rate of data asset growth, and facilitates cross-domain data-flow towards a thriving data-driven EU economy.
