Since network wiring between carriages may be difficult or often impossible, particularly in case of refurbishment operations because of aging or poor quality connectors, WiFi has naturally established itself as the most efficient solution by allowing redundancy, reliability and high-speed networking.
ACKSYS’ SRCC solution relies on wireless couplers that only need to be configured once and thus :
- supports any train composition change
- provides a redundant and reliable onboard network
SRCC and to train-to-trackside communication combined offer a complete network solution based on wireless to answer any application need : CBTC, CCTV, PIS, passengers WiFi access…
