LTE Router

Digi International®, a leading global provider of mission-critical machine-to-machine (M2M) and IoT connectivity products and services, today introduced the Digi TransPort® WR31, a rugged, versatile enterprise LTE router built for critical applications operating in harsh environments. The WR31 features advanced security and monitoring and the intelligence to operate on nearly any 3G or 4G LTE network in the world.

Designed for critical infrastructure environments, the WR31 addresses industries that manage a large number of remote assets installed in challenging environments where onsite visits are infrequent or impractical. In addition, by supporting global HSPA+ and 4G LTE networks, the WR31 provides customers the flexibility to future-proof their router installation as wireless network requirements evolve.

Industrial Grade Intelligence to Meet Industry Requirements

At the heart of the WR31 is Digi’s license-free enterprise routing and security software that supports features required for high reliability and high-security applications in utility and industrial markets. The WR31 is ideally suited for SCADA, telemetry and other network operations teams. It is targeted for installation at electric and water utilities, state and municipal traffic agencies, oil/gas production and distribution facilities, and manufacturing automation companies.

Multi-Carrier Flexibility for Optimal Choice

The WR31 is available in multiple variants to allow companies the ability to leverage increasingly affordable and available cellular connectivity by offering software selectable 3G/4G LTE in order to choose the best network and carrier for their needs.

For North America, the WR31 joins the Digi TransPort family of M2M routers that offers Gobi 4G LTE capabilities to give customers the ability to connect to either Verizon, AT&T, or Sprint’s 2G, 3G and 4G networks across North America using a single device.

For international deployments the WR31 is available in either global LTE with HSPA+ fallback or global HSPA+ versions.

As a result, the Digi TransPort WR31 easily and reliably connects a broad set of geographically distributed devices to allow companies to quickly scale their M2M deployments without worrying about which carrier and network type is best for each location.

Hardened for Any Installation Scenario and Situational Understanding

With a ruggedized aluminum enclosure and DIN-rail form factor, the WR31 is designed for use in cabinets, weatherproof enclosures and substation sheds. The product meets Class 1/Division 2 and ATEX ratings for use in hazardous environments and includes I/O support for local sensing and alarming applications.

Three-Tiered Always-On Approach

Operators who deploy the WR31 have three tiers of support for keeping devices online. Digi Remote Manager(SM) provides a centralized portal for configuring devices en masse and reporting potential problems. Digi’s enterprise software supports redundancy features like Digi’s patented VRRP+ (Virtual Routing Redundancy Protocol) and patented SureLink™ connection persistency software. Finally, the WR31 supports dual SIMs to provide continuous service through failover from one service provider to another which is essential for applications that require continuous network connectivity and must adhere to service-level agreements (SLA).

“The Digi TransPort WR31 was built specifically for network engineers with hard hats,” said Joel Young, chief technology officer at Digi International. “No longer will they have to settle for a vendor that has tried to tack 3G onto a legacy industrial product; they can have an advanced 4G LTE router plus Digi’s proven serial, IP and I/O networking capability.”

The Digi TransPort WR31 is available at an MSRP of $589 to $699 with an enterprise software license and five-year warranty included. For a listing of authorized distributors offering the product or for more information, visit:
