Uninterrupted Communication. Zero Maintenance. Limitless Mobility.
In modern rail transport, connectivity is no longer a luxury, it’s an operational necessity. From real-time passenger information systems to onboard Wi-Fi and safety monitoring, every function depends on seamless, high-speed communication across train carriages.
Traditional wired inter-carriage systems, once the backbone of onboard connectivity, are now reaching their limits. Mechanical couplers suffer wear and tear. Fiber connections require costly maintenance. And as train compositions evolve, reconfiguring these systems adds complexity and delay.
Check out RADWIN’s Wireless Inter-Carriage Link (WICL), a revolutionary 60 GHz mmWave solution that eliminates the wiring challenge, offering gigabit-speed connectivity with zero maintenance and maximum reliability.
Train Connectivity: Powered by 60 GHz mmWave
RADWIN’s WICL leverages advanced 802.11ad 60 GHz millimeter-wave technology to deliver ultra-high-speed communications between carriages, exceeding 1.5 Gbps of aggregated throughput.
This innovation transforms how railway operators design, deploy, and maintain onboard networks.
Supports over 1.5 Gbps for seamless data exchange across train cars.
Works with any train composition, static or dynamic, with minimal setup.
A lightweight, low-profile form factor that mounts discreetly, preserving train aesthetics.
No moving parts or physical couplers, drastically reducing downtime and servicing.
Overcoming the Limits of Wired Systems
Legacy wired systems introduce challenges that impede both efficiency and innovation:
- Mechanical wear and fiber fatigue lead to periodic failures and costly replacements.
- Fixed coupling constraints complicate dynamic train configurations.
- Signal interruptions and latency reduce reliability for mission-critical systems.
The Wireless Inter-Carriage Link removes these constraints entirely. Using short-range, high-frequency mmWave transmission, it ensures stable, interference-free connectivity even as train carriages move or reconfigure
Designed for Reliability in Motion
Railways operate in harsh conditions; vibration, dust, humidity, and temperature extremes are constant challenges. RADWIN’s WICL was purpose-built for these environments.
Automatically maintains connectivity across changing carriage configurations.
Operates in the 60 GHz band, isolated from congestion in the 2.4 and 5 GHz ranges.
IP69K-rated for outdoor installation, resistant to vibration, water, and debris.
Operational Excellence Onboard
Beyond convenience, RADWINs WICL represents a fundamental step forward in railway digital transformation.
It enables new levels of operational efficiency and passenger experience:
- Superior Data Transfer: Real-time video, diagnostics, and passenger information delivered at gigabit speeds.
- Enhanced Passenger Experience: Supports uninterrupted Wi-Fi, infotainment, and smart mobility services.
- Reduced Maintenance Costs: Eliminates physical couplers and wiring, minimizing lifecycle costs.
- Future-Ready Scalability: Adapts easily to new rolling stock, train compositions, and onboard systems.
RADWIN WICL gives operators the performance and flexibility they need to meet tomorrow’s demands today.
