- Cybersecurity, 5G, AI and radio optimisation are some of the issues analysed in this article, which summarises some of the 101 interviews published in 2025.
Throughout the year, we have been publishing a series of interviews on this blog in which we have met people from Telefónica whose knowledge in a wide variety of specific areas has helped us to learn and delve deeper into a wide range of issues.
Why were 101 interviews conducted? There are several reasons.
On the one hand, from a technological or scientific point of view, this number is related to the American university course coding system, where it is used to name the introductory beginner-level course in a subject. In addition, it has the curious distinction of being both a palindrome and a prime number.
From a historical perspective, in 2025 Telefónica will have been in existence for precisely 101 years: more than a century of evolution in parallel with society, positioning itself as a leader and technological benchmark.
In the following article, we will review some of the interviews, although we encourage you to read them all in the section of the website.
AI agents: a transformative and profound impact
Elena Gil Lizasoain reviews the impact that AI agents will have on organisations in the coming years, although she considers that the evolution of this technology alongside the IoT and Big Data is both exciting and challenging.
In addition to the social and business impact, Gil highlights the influence in the healthcare field, although she emphasises the challenges of implementing Artificial Intelligence, such as the integration of existing systems, the shortage of qualified talent and resistance to change due to fear of automation.
WiFi or 5G?
Our colleague María José Angulo reflects in her interview on the differences and similarities between WiFi and 5G.
As an expert in Mobile Access Quality Analysis, she also breaks down the parameters for measuring network quality, such as accessibility, availability, signal strength, latency, drop rate, failed attempt rate, and upload and download speed.
Another issue to consider is that in order to address network quality, the focus is on handling diversions, managing interference, responding to complaints, and validating power-ups.
Coverage, vital in mobile communications
María del Carmen Jiménez González, an expert in radio optimisation, summarises its importance as follows: coverage is a vital part of mobile communications.
With regard to radio optimisation processes, she explains that this involves studying improvements and understanding the evolution of each technology, monitoring the worst-performing nodes, participating in special projects, and testing tools that help to optimise the network.
Radio optimisation aims to provide users with the best customer experience on the mobile network
María Ángeles Núñez also talks about radio optimisation to explain its benefits for the customer, from detecting areas without coverage to restoring services in degraded areas, including reinforcement at large events or enabling users to watch high-quality videos or send content more quickly.
This work is based on knowledge, detection and evolution, seeking to help users have the best customer experience on the mobile network, including not only browsing but also voice calls.
Innovation is not an extra, it is part of the DNA of digital companies
Javier Ortiz works in the world of B2B and in his interview 101 he delves into digitally native companies, a type of company for which innovation is the driving force, something that is in their DNA.
Similarly, he points out that, just because they were born digital, it does not mean they are not at risk of becoming obsolete if they do not continue to transform themselves, with digital transformation being not only a tool for consolidation, but also for expansion.
Don’t expect to see light if you look at fibre optics
David Osado explains what fibre optics are and how they work, summarising their advantages in terms of low losses and ease of deployment.
Far from being monolithic, fibre optics come in different types to suit different uses or installation locations, including single-mode, multi-mode and other types such as plastic or hollow fibre.
Women leaders in science and technology are key to breaking stereotypes
Historically, women in technological and/or scientific fields have been relegated. That is why Estefanía Arias highlights the importance of having female role models in STEM subjects, breaking with this legacy and advocating for women to fight to occupy their rightful place.
In her interview, the engineer also explains the innovations linked to the development of 5G technology, citing low latency in online gaming and the user experience in streaming as tangible and obvious examples of the benefits of this fifth generation of mobile telephony.
5G is like giving superpowers to our usual Internet connection
Mónica Ramírez also talks about 5G, summarising the role of this technology as follows: it is like giving superpowers to our usual Internet connection.
The following example makes it even clearer: 5G would be like going from a normal two-lane road to one with many lanes of ultra-fast traffic, because unlike previous mobile generations, it offers higher transmission speeds, the ability to connect a greater number of devices, and lower latency.
The main threat to cybersecurity is that everything is cyber-connected
It may seem obvious, but Noel Calderón highlights that the main threat to cybersecurity lies in the fact that everything is cyber-connected.
He therefore considers cybersecurity to be indispensable in an era in which the use of connected electronic devices is increasing and open connections from these devices are also becoming more frequent.
From almost an ‘extra’ to a strategic necessity
Also linked to cybersecurity, Ester Bermejo’s interview reminds us that this discipline has gone from being practically an extra to becoming a strategic necessity.
Similarly, she also highlights the professionalisation of threats and the fact that the attack surface has grown exponentially, which are among the reasons why cybersecurity has had to evolve to incorporate AI, automation, detection and advanced response.
We are not fully aware of the enormous danger that exists on the Internet
Daniel Consentini stresses that we are not fully aware of the enormous danger that exists on the Internet and reminds us that cybersecurity is involved in every digital step we take.
Based on confidentiality, integrity, availability, authenticity and non-repudiation, Consentini defines cybersecurity as the branch dedicated to the protection of information and the secure availability of all digital assets.
