[International Conferences] Shared Antennas, Shared Risks
Alexandre Vogel, Cristel Pelsser
As critical systems increasingly rely on machine-to-machine (M2M) communications, the demand for highly resilient connectivity has never been greater. While multipath protocols are often used to switch between different access technologies, they can also leverage multiple providers for the same type of access technology to enhance resilience. New multipath communication protocols have emerged to utilize multiple network interfaces simultaneously, offering more stable and robust mobile connections. However, a key question remains: Which operators should be selected to achieve truly resilient connections? To address this, we collected and analyzed public data to identify the locations of sites, the antennas installed at these sites, and the operators using these antennas, including the evolution of antenna sharing over time. In some cases, we also obtained details about the manufacturers and models of the antennas. Our analysis reveals the extent of antenna sharing among operators and the associated risks to resilience. Such an analysis is essential for selecting operators for critical systems relying on multipath communication protocols.
[Poster] Impact of Road Congestion on Mobile Networks

With the increasing number of vehicles equipped with connected services, whether it's security services (eCall, Emergency Assist by Volkswagen, etc.) or infotainment systems (Android Auto, Apple CarPlay, proprietary systems), the automotive sector has become a consumer of bandwidth on cellular networks. Furthermore, the habits of road users have evolved, and they are leaving traditional radio behind in favor of audio streaming services for entertainment, which is also a source of traffic that must be managed by cellular networks.
