One of the major concerns of rail operators is to establish a high-speed, reliable and continuous communication between a train in motion and the trackside for a smooth CBTC operation and also to collect data from CCTV, preventive maintenance, VoIP, PIS, etc. and retrieve real-time information of these data streams.
> THESE APPLICATIONS REQUIRE HIGHLY-AVAILABLE NETWORKS.
ACKSYS’ latest products combining WiFi 802.11ac and cellular connectivity enable a truly uninterrupted communication to be established with a seamless data flow between the on-board equipment and the trackside thanks to :
- a < 30 ms roaming between APs allowing error-free communications
- a redundant train-to-ground wireless link allowing a continuous communication even in case of failure of one trackside AP or one onboard client
- up to 500 Mbps high-speed data throughput at 350 km/h
