Now enabling 5G applications to run on trains, the HUBER+SUHNER SENCITY Rail ACTIVE Rooftop antenna is the first-of-its-kind rail antenna that contains an embedded radio and compute module to offer increased data throughput to support 5G services. It is an all-in-one active antenna with a single ethernet cable input for power and data transmission. Travellers will be able to benefit from improved Wi-Fi connectivity, while system integrators can also benefit from having more advanced hardware in order to deploy their applications.
To meet modern communication requirements, infrastructure must offer high rates of data throughput. 4×4 Multiple Input, Multiple Output (MIMO) systems have the potential to meet this data demand using 5G and later releases of 4G technologies. However, it involves many radio frequency (RF) cables which take up space, are costly and complex to install and result in performance losses over time.

“Without the need for multiple RF cables, the rollout of 5G is streamlined and train operators and rolling stock providers can benefit from up to 33 percent capex savings, as well as increased space inside the carriage. Tests have proven there is a significant increase in throughput and coverage due to improved signal quality. The antenna also enables deployment of edge computing applications in public transport fleets, such as McLaren Applied’s Fleet Connect. It brings connected trains one step closer to connected cars,” said Pablo Garcia, Head of Transport at McLaren Applied.
Operators now want to monitor real-time vehicle metrics, as well as trackside factors such as overhead, vegetation, and security – this trend will be accelerated with the uptake of commercial 5G in rail in the next couple of years. The active antenna provides the platform that can host an array of applications to achieve this, removing the need of extra computers in the train, offering further savings on space and weight.
