Switzerland, innovation and Comfone

comfone-modern-innovatio_20210507-072411_1
I am originally from Spain, and my path led me to Switzerland when I married a Swiss guy. I have to admit that before I moved here, the only things I knew about this country were clichés… cows, chocolate, mountains, punctuality… But, once I started to live here and got to know the place better, I realised that this small country has way more to off...

Roaming is about cooperation

handshake-_20210430-083155_1
 Roaming can be turned on by our phones in one swipe, but it's not 1-swipe task for operators to implement. On average, each single network is connected to 600-700 other networks around the world. This allows subscribers to roam reliably worldwide. Did you know and there are more than 1200 operators globally?   Roaming agreements Thi...

Machine Learning - what's it all about?

comfone-machine-learning
When I began in my role as Senior Data Scientist at Comfone in 2020, it became my mission to help Comfone to make progress with machine learning. Machine learning can have a reputation as something extremely complex and impenetrable, and a lot of people find it 'scary' to approach. However, I have dedicated a lot of my working life to Machine Learn...

Why are TDRs so interesting for Comfone engineers?

TDR-comfone-bik_20210126-124950_1
When somebody overhears talk about a TDR, their first thought might be about the WHO's Research and Training for Tropical Diseases, 'ticket deposit receipt' or even a Yamaha TDR motorcycle...  However, I work at Comfone, so when somebody mentions 'TDR', my mind jumps straight to 'Transaction Data Records'. Most people in roaming might think th...

Connection, communication and Comfone

Comfone-teamwork-internationa_20201118-100048_1
As they say in German, 'Der rote Faden' (or red thread) signifies a "coincidental recurring theme". In nature as in life, I am aware of the same constant themes. Communication, connection, inter-connection, constant evolution, endings and beginnings, growth and sustainability, resilience and creativity are the themes that run through our lives, whi...

Times have changed: A peek at the past and look towards the future

Comfone-past-tec_20201028-131456_1
When I look back at my childhood in the 1980s, the way that we share information has changed significantly. In the past, I received news by listening to radio broadcasts, or tuning into TV news channels at specific times. Sometimes it was even necessary to wait for the newspaper to acquire the details. In the 1980s it was also not unusual to go to ...
