Yes, WayFi Wireless’s Wi‑Fi DAS – a cellular over Wi‑Fi solution – is ideal for boosting connectivity in transit and rail environments. It leverages existing Wi‑Fi infrastructure with technologies like Passpoint® and OpenRoaming to provide seamless, secure connectivity for passengers and staff. This innovative approach automatically switches devices between cellular networks and Wi‑Fi, ensuring uninterrupted service even in tunnels or remote areas. With reliable coverage and cost-effective deployment, it’s a smart solution for today’s high-demand transit systems.

Connectivity Challenges in Transit & Rail

Staying connected on public transit is essential for modern commuters. However, transit systems face unique challenges such as:

• Signal Dead Zones: Tunnels, underground stations, and moving vehicles can block cellular signals, causing dropped calls and intermittent service.

• Network Congestion: During peak hours, hundreds of data-hungry users can overwhelm cellular networks.

• Infrastructure Limitations: Traditional Distributed Antenna Systems (DAS) are expensive and time-consuming to install.

• User Frustration: Commuters expect constant connectivity, and interruptions can negatively impact customer satisfaction.

Transit agencies need a cost-effective, efficient solution to bridge these gaps and provide a smooth connectivity experience.

What is Wi‑Fi DAS (Cellular over Wi‑Fi)?

Wi‑Fi DAS uses your existing Wi‑Fi infrastructure to carry cellular data and voice services. Here’s how it works:

• Passpoint® Secure Wi‑Fi: WayFi Wireless integrates Passpoint® technology so that any Passpoint-enabled smartphone can automatically connect to onboard or station Wi‑Fi without the hassle of manual login.

• Carrier-Grade Integration: Once connected, data and voice traffic are securely tunneled to the appropriate mobile carrier. This means calls and texts work seamlessly, just as they would on a traditional cellular network.

• Seamless Roaming: Utilizing OpenRoaming, devices can transition effortlessly between different Wi‑Fi networks and cellular coverage. This ensures continuous, secure connectivity throughout the journey.

• Cloud-Based Offload: The solution intelligently shifts data from cellular networks to Wi‑Fi, relieving congestion and providing faster speeds during peak usage.

With this approach, the transition between 5G/LTE and Wi‑Fi is invisible to the user, ensuring that connectivity is maintained at all times.

WayFi Wireless’s Implementation Process

WayFi Wireless’s solution is designed to integrate seamlessly with existing transit infrastructure. Here’s how it works:

1. Utilize Existing Wi‑Fi: WayFi leverages current Wi‑Fi access points already installed in trains and stations, reducing the need for new hardware.

2. Enable Passpoint® & SIM Authentication: A dedicated Passpoint‑enabled SSID is set up, allowing automatic authentication for subscribers of major carriers.

3. Seamless Handoffs: The cloud platform manages handoffs between cellular and Wi‑Fi, ensuring no dropped calls as devices move between networks.

4. Secure Tunneling & Traffic Management: Voice calls are encrypted and tunneled to the carrier’s core network, while data is efficiently routed for optimal performance.

5. Carrier Partnerships: Collaborations with leading mobile carriers and participation in the OpenRoaming federation ensure wide compatibility and effortless user experience.

This solution is vendor-agnostic, working with major Wi‑Fi platforms like Cisco, Aruba, and Ruckus, making it both flexible and future-proof.

Benefits for Transit & Rail Operators

For transit and rail decision-makers, the benefits of adopting Wi‑Fi DAS are clear:

• Enhanced Passenger Experience: Riders enjoy continuous, high-speed connectivity for streaming, work, and communication. This results in a smoother, more satisfying travel experience.

• Improved Safety & Operations: Reliable connectivity allows for real‑time service alerts and emergency notifications, enhancing safety and operational efficiency.

• Cost Efficiency: Deploying Wi‑Fi DAS is far more affordable than traditional DAS systems, which require extensive infrastructure and lengthy installation processes.

• Carrier Offload: Offloading traffic to Wi‑Fi reduces congestion on cellular networks, ensuring faster speeds and better performance for everyone.

• Rapid Deployment: Utilizing existing Wi‑Fi infrastructure means installations can be completed quickly, minimizing service disruptions.

WayFi’s Wi-Fi DAS solution can leverage the same infrastructure that provides passenger Wi-Fi to also carry cellular services, creating a unified connectivity experience.
