Multi-Carrier Cellular Access (MCCA) allows cellular users to dynamically connect to different cellular networks without switching their SIM card.
There are a number of advantages that can be realized through MCCA. MCCA users can improve coverage and performance, combining measurement-based dynamic carrier selection and predefined preferences on radio access technology (RAT) use (3G, 4G, 5G, wifi), irrespectively of which carrier is offering it a particular location.The objective of the project is characterise the performance of MCCA services while roaming. We will collect quantitative information to help us understand the benefits and downsides of MCCA service when used abroad. We will focus our analysis to clients from MCCA operators in the US that are roaming in the EU and investigate how their performance compares to both traditional US carriers while roaming and local EU carriers while providing local services in the visited network.
MCCA enables the provision of mobile communication services without the need of having a radio access network infrastructure (much like a virtual MNO) and its technology has the potential to offer an even better performance than traditional MNOs.
This experiment has concluded.
