Engineering Transparency Notice

Is this for North America or Police Vehicles? NO. The Valtoris VT-LTE400 is purposely engineered as a Category 1 fixed-site SCADA router. It does not support North American cellular bands, and it lacks the “Ignition Sense” pins required for mobile fleet deployments. It is exclusively designed to replace legacy 3G/Early 4G modems in stationary industrial cabinets across Europe, Asia, the Middle East, and Africa.

Why Right-Sizing Your Hardware Matters

As older AirLink devices reach End-of-Life (EOL), many vendors force integrators to upgrade to expensive 5G Gigabit routers. For a Modbus PLC transmitting 5KB/s, this is a massive waste of CapEx. The VT-LTE400 solves this.

1. Perfect Bandwidth Match

SCADA telemetry does not require broadband. The VT-LTE400 utilizes an efficient LTE Cat 1 chipset, delivering 10Mbps down and 5Mbps up. This easily handles MQTT payloads, Modbus polling, and remote PLC programming without over-engineering the hardware.

2. Eliminate the Cabinet Switch

Legacy Raven and LS300 modems generally only have one Ethernet port, so you will need to buy another DIN-rail switch to connect multiple PLCs. The VT-LTE400 features four 10/100M LAN ports and a WAN port built into the chassis.

3. Hardwired IPSec VPNs

Security cannot be compromised. The VT-LTE400 features native firmware support for modern L2TP/IPSec and WireGuard tunnels. It includes full Phase 1/Phase 2 IPsec parameter controls (IKEv1/v2, AES256, DPD) to seamlessly integrate into your existing corporate firewall.

The TCO Reality Check: Right-Sizing Your SCADA Hardware

As legacy AirLink devices face End-of-Life, many dominant vendors are forcing integrators into “upgrading” to highly expensive Gigabit LTE or 5G routers. For remote Modbus telemetry, this is a massive misallocation of your budget.

Why LTE Cat 1 is the Engineering Sweet Spot

  • Stop Paying for Unused Bandwidth: SCADA protocols (MQTT, DNP3, Modbus TCP) transmit kilobytes of data, not gigabytes. The VT-LTE400’s Cat 1 modem (10Mbps) is mathematically perfect for telemetry, eliminating the premium cost of Cat 12/5G chipsets.
  • Lower Power Consumption: High-speed routers draw significant amps. Our Cat 1 gateway is highly power-efficient, making it strictly better for solar-powered enclosures, remote battery sites, and water lift stations.
  • Thermal Reliability: By not using unnecessary gigabit processors the VT-LTE400 generates much less heat, greatly extending its life when installed in unventilated, sun-baked outdoor control panels.
  • Reclaim DIN-Rail Space: By replacing your old single port modem and external unmanaged switch. Our integrated 4-port LAN switch reduces your cabinet architecture and eliminates a common point of failure.

Direct Answers to Integrator Questions

Does the VT-LTE400 support North American carriers like AT&T or Verizon?
No. The VT-LTE400 is strictly engineered for LTE-FDD B1/B3/B5/B7/B8/B20 bands. It is the perfect EOL replacement for sites located in Europe, Asia, the Middle East, and Africa, but it will not operate on North American cell towers.
Is this router suitable for Police Fleets or Ambulance Mobile Data Terminals?
No. Emergency vehicle fleets require Gigabit throughput for video streaming and physical “Ignition Sense” pins to manage vehicle battery drain. The VT-LTE400 utilizes a DC 9V~24V terminal block without ignition sensing, and operates at 10Mbps. It is exclusively designed for fixed-site industrial enclosures (like pump stations and electrical substations).
How does the router handle cell tower connection drops at remote solar-powered sites?
For remote telemetry, the VT-LTE400 features a built-in hardware watchdog and ICMP keep-alive polling. If the cellular connection stalls or the tower resets, the modem automatically re-establishes the connection without requiring a technician to drive out and perform a manual power cycle.
Can I replace a legacy router and an unmanaged switch with this single unit?
Yes. Legacy modems often only have a single LAN port. The VT-LTE400 integrates a 4-port 10/100M LAN switch with full VLAN support. This allows you to connect a PLC, an HMI, and an IP camera directly into the router, saving money and precious DIN-rail space inside your control cabinet.
