As railway systems modernize, the demand for high-throughput, ultra-reliable connectivity has expanded beyond back-office operations to encompass onboard Wi-Fi, train telemetry, real-time positioning, and safety systems. The Digi TX64-R210 rises to meet these challenges, a rugged, rail-certified 5G router with dual Wi-Fi, LTE-Advanced Pro Cat 20, and untethered dead reckoning (UDR).
But the hardware is only part of the equation. To achieve resilient 5G connectivity across high-speed rail environments, precision RF design and specialized antenna systems from AG Antenna are essential.
Purpose-Built for Rail Applications
The Digi TX64-R210 isn’t just another cellular router, a rail-certified communications gateway engineered for extreme mobility and harsh physical conditions. It delivers:
- 5G NR sub-6GHz with global band support (n1–n79, including n48 CBRS and n77/n78 C-band)
- LTE-Advanced Pro Cat 20 fallback (up to 2 Gbps download speeds)
- Dual concurrent Wi-Fi 6 radios for simultaneous passenger and backhaul service
- Untethered Dead Reckoning (UDR) using GNSS + inertial navigation for continuous positioning
- M12 X-Coded Gigabit Ethernet, serial, USB, and M12 power with ignition sense
Whether installed on a high-speed train, a light rail system, or a commuter fleet, the TX64 is engineered for real-world rail environments.
5G / LTE-Advanced Pro Cellular Performance
At the heart of the TX64 is its advanced 5G modem, supporting a full range of global 5G NR bands. It delivers reliable mobile broadband, even at 300 km/h, across:
- 5G Sub-6 GHz: including n77, n78, n79 for C-band and mid-band 5G
- CBRS (n48): private LTE/5G support for enterprise rail operators
- FirstNet (B14): priority access for public safety integration
- LTE-A Pro Cat 20: peak fallback speeds of 2 Gbps down / 150 Mbps up
- 3G HSPA+ fallback for compatibility with legacy cellular infrastructure
For mobile rail applications that demand constant high throughput—passenger internet, fare collection, telemetry, or video surveillance—the TX64 delivers.
Untethered Dead Reckoning (UDR): Accuracy Beyond GNSS
Rail networks face unique GPS challenges in tunnels, urban canyons, and intermittent reception. The TX64-R210 features Untethered Dead Reckoning, which combines GPS/GNSS with an onboard inertial measurement unit (IMU) to maintain accurate positioning even when satellite signals are lost.
This is particularly valuable for:
- Safety-critical train tracking in GNSS-denied areas
- Fare enforcement validation
- Real-time onboard diagnostics
- Future FRMCS compliance
Dual Wi-Fi 6 for Passenger and Onboard Networking
Equipped with dual concurrent Wi-Fi 6 (802.11ax) radios, the TX64-R210 supports:
- Public SSID for passenger Wi-Fi (2x2 MU-MIMO, 128 clients)
- Private SSID for backhaul, camera feeds, and rail control systems
- Flexible VLAN and QoS configurations to prioritize traffic
This dual-radio design is ideal for separating mission-critical rail infrastructure from public internet access without additional hardware.
Digi Software Suite and Centralized Management
The TX64-R210 is supported by Digi’s powerful software ecosystem:
- Digi Remote Manager® (included in Digi 360): full remote configuration, OTA updates, health monitoring
- Digi WAN Bonding: aggregates multiple WAN links (cellular, Ethernet, Wi-Fi) for improved speed and redundancy
- Digi TrustFence® Security Framework: secure boot, firewall, port lockdown, FIPS 140-2 validated crypto
- Digi Containers: run Python scripts, ML models, or edge applications locally
For large rail operators or integrators, this means scalable deployment and fleet-wide control from a single dashboard.
AG Antenna: Optimizing RF for Rail Environments
High-speed rail environments introduce unique RF challenges: Doppler shift, vibration, signal multipath, and cell reselection under high mobility. AG Antenna delivers antenna systems that are purpose-engineered for these use cases.
Recommended Solutions from AG Antenna:
- Multi-band 5G/LTE antennas with support for CBRS, C-band, and FirstNet
- Low-profile MIMO Wi-Fi antennas designed for roof or undercarriage installation
- GNSS/UDR antennas with ruggedized enclosures and high-sensitivity elements
- Custom coaxial cable assemblies (AGA240/AGA400) for minimal loss and vibration resistance
- Surge protection and grounding kits for outdoor rail environments
AG Antenna not only supplies antennas—we ensure that RF performance is optimized by design, accounting for placement, gain, VSWR, radiation pattern, and cable path attenuation.
