In today's fast-paced, connected world, passengers expect seamless internet access when traveling by train. While onboard Wi-Fi has long been the default solution, it comes with significant cybersecurity risks and performance limitations. Pulsaart by AGC offers a better, safer, and more efficient alternative—WAVETHRU™ Retrofit—to allow passengers to connect directly to their mobile networks inside the train without the need for public Wi-Fi.

The Hidden Cybersecurity Risks of Public Wi-Fi on Trains
Public Wi-Fi networks, even when password-protected, expose passengers to a range of cyber threats:
Man-in-the-Middle (MITM) Attacks – Hackers can intercept data between passengers and the internet, potentially stealing sensitive information like login credentials and credit card details.
Evil Twin Attacks – Attackers set up fake Wi-Fi networks that mimic the train's official network, tricking passengers into connecting and exposing their data.
Data Snooping & Packet Sniffing – Cybercriminals can monitor unencrypted traffic, capturing passwords, emails, and private messages.
Malware Injection & Phishing – Fake login portals can trick passengers into entering personal information or downloading malicious software.
With so many risks, relying on public Wi-Fi for connectivity is far from ideal for both passengers and train operators.
How WAVETHRU™ Retrofit Eliminates These Risks
Instead of relying on a shared, vulnerable Wi-Fi network, WAVETHRU™ Retrofit enables direct mobile network access by making train windows permeable to mobile signals (4G, 5G) while preserving thermal insulation properties. This secure-by-design approach offers multiple advantages:
1. No Need for Public Wi-Fi
Passengers connect directly to their own mobile network, completely bypassing the security risks associated with shared Wi-Fi.
2. No Login Portals or Third-Party Authentication
Unlike public Wi-Fi, which often requires users to log in through portals, WAVETHRU™ lets passengers stay connected without any interruptions or security concerns.
3. Protection from Network Snooping and Hacking
On public Wi-Fi, every connected device shares the same network, creating vulnerabilities such as:
Lateral movement attacks, where a compromised device can scan and infect others.
Session hijacking, where attackers steal authentication tokens to take over online accounts.
DNS spoofing, which redirects users to fake banking or social media sites to steal credentials.
With WAVETHRU™, each passenger's connection is isolated and protected by their mobile provider's built-in security measures.
4. No Data Collection by Third Parties
Many onboard Wi-Fi services are managed by third-party providers that:
Track and collect user browsing data for analytics or advertising.
Sell anonymized passenger behavior insights to external companies.
Monitor device MAC addresses, raising privacy concerns.
With WAVETHRU™, passengers remain in complete control of their data, as they are directly connected to their trusted mobile network.
5. Increased Reliability and Resilience
Public Wi-Fi networks are vulnerable to cyberattacks, including denial-of-service (DDoS) attacks, which can disable connectivity for all passengers. By removing the need for centralized Wi-Fi infrastructure, WAVETHRU™ eliminates this single point of failure, ensuring a more resilient and secure passenger experience.
The Future of Secure, High-Performance Connectivity in Rail Transport
With the rise of 5G and high-speed mobile networks, there is no longer a need for costly, vulnerable onboard Wi-Fi systems. WAVETHRU™ Retrofit provides a superior alternative—one that enhances passenger experience while eliminating cybersecurity risks.
Key Benefits of WAVETHRU™ Retrofit for Trains
✅ No public Wi-Fi vulnerabilities – Eliminates hacking and data theft risks.
✅ No login interruptions or tracking – Seamless, secure mobile connectivity.
✅ No shared networks or exposure to hacking – Direct 4G/5G access for every passenger.
✅ Full-speed, congestion-free mobile connectivity – No bandwidth limitations.
✅ Lower costs and zero maintenance for train operators – No need for expensive infrastructure.
As the demand for seamless and secure onboard connectivity grows, WAVETHRU™ Retrofit is setting a new standard for the railway industry. It's time to move beyond outdated Wi-Fi solutions and embrace a smarter, safer, and more efficient way to keep passengers connected.
Keeping passengers connected has never been easier—or safer.
