WAN Failover for the Real World: 5G/LTE + Satellite Resilience with ORVIWO

WAN Failover for the real world: ORVIWO designs resilient connectivity that automatically switches between T-Mobile 5G/LTE and Starlink satellite to keep operations online when the primary link drops.

Why WAN failover matters now

Connectivity is no longer “nice to have.” It’s the backbone of operations:

• coordination, dispatch, and field reporting

• video and sensor visibility

• remote access and cloud workflows

• secure communications between sites and vehicles

The problem is simple: one link will fail—or degrade—at the worst time.

WAN Failover is the architecture that keeps you online by automatically switching traffic to backup connectivity, without waiting for a technician.

ORVIWO’s approach: Multi-path connectivity you can trust

ORVIWO engineers failover like an operational capability, not a checkbox:

Layer 1: 5G/LTE as the fast, local backup

A rugged 5G router provides primary/secondary backhaul for vehicles, mobile command, and remote sites. For example, Semtech’s AirLink XR60 is positioned as an ultra-compact rugged 5G router built for harsh environments and vehicles. Semtech (formerly Sierra Wireless)+1

Layer 2: Satellite as the independent last-resort path

When towers are unreachable or disasters impact terrestrial networks, satellite becomes the independence layer. Starlink’s business positioning for its “Performance” hardware emphasizes rugged use (aluminum enclosure), harsh environments, in-motion usage, AC/DC power, and resilience language including warranty/survivability claims.

Layer 3: Phone-level satellite backup (people stay reachable)

For personnel safety and “dead zone” continuity, T-Mobile’s T-Satellite with Starlink is positioned as texting + select satellite-ready apps in outdoor areas where you can see the sky, powered by 650+ direct-to-cell satellites. T-Mobile+1

Reference architecture (simple and practical)

At the edge (site / vehicle / vessel):

• Semtech AirLink router provides 5G/LTE WAN

• Starlink provides Satellite WAN

• The edge gateway runs:

  • automatic failover

  • traffic prioritization (critical apps first)

  • secure tunnels for continuity (so “switching WAN” doesn’t break operations)

Outcome: when 5G/LTE degrades or fails, traffic moves to satellite. When cellular returns stable, traffic returns gracefully—without “bouncing.”

How the failover decision should work (operational logic)

A resilient design should trigger failover on failure OR degradation, such as:

• loss of reachability (can’t reach multiple test targets)

• excessive latency / packet loss

• repeated session drops

And it should include controlled failback:

• don’t switch back immediately

• require stability for a defined window

• avoid flapping between 5G/LTE and Satellite during recovery

---

Where this matters most

• Public safety & emergency response: congestion + coverage gaps + rapid mobility

• Critical infrastructure: remote sites, substations, ports, utilities

• Maritime: offshore operations where terrestrial coverage disappears

• Enterprise continuity: keeping branches online when primary circuits fail

For agencies using T-Mobile’s public safety offerings, T-Priority is positioned as a 5G standalone network slice built to keep first responders connected during congestion. T-Mobile+1

Call to action

If you want a site/vehicle/vessel WAN-Failover blueprint, ORVIWO can map:

1. primary/secondary/tertiary connectivity paths

2. failover thresholds and recovery logic

3. traffic priorities (what must keep working first)

Need a failover blueprint for your site, vehicle, or vessel?
