Cellular Internet Backup

Your Business Stays Online
Even When Your ISP Doesn't.

Every minute your internet is down costs real money — failed transactions, unreachable customers, stalled operations. Alpine IT installs cellular 5G and LTE backup systems that automatically take over within seconds, with no manual intervention required.

The Real Cost

Internet Downtime Isn't an Inconvenience. It's a Business Interruption.

A restaurant can't run a credit card. A retail store can't process a sale. A service business can't reach a client. When your ISP has an outage — and they all do — your business pays for every minute of it.

The average small business internet outage costs hundreds to thousands of dollars depending on duration and industry. And most ISPs don't guarantee uptime — their SLAs often only credit you a few dollars in service credit after the fact.

Cellular backup changes the equation entirely. When your primary connection drops, 5G or LTE automatically picks up the load within seconds. Your staff keeps working, your transactions keep processing, and your customers never know anything happened.

Alpine IT installs UniFi Multi-WAN gateways with SLA-based failover. The system continuously monitors your primary connection's quality — not just whether it's "connected," but whether it's actually delivering acceptable performance. The moment it doesn't, failover is instant.

Common Downtime Scenarios
ISP Outage or Maintenance

Scheduled or unscheduled ISP outages can last hours. No warning, no timeline, nothing you can do — without a backup.

Physical Cable Cuts

Construction, utility work, or accidents can sever fiber or coax lines. These take 4–24 hours to repair.

Severe Weather

Colorado weather — high winds, ice, snow — knocks out above-ground infrastructure. Cellular towers are typically more resilient.

Building or Power Issues

Equipment failures, power disruptions, or building maintenance can bring your wired connection down without touching the ISP.

How It Works

Intelligent Failover — Automatic, Seamless, Invisible.

Alpine IT configures UniFi Multi-WAN gateways with SLA-based failover logic. The system actively tests your primary connection's real-world quality every few seconds — not just ping, but packet loss and latency. If it degrades past your threshold, cellular takes over instantly.

SLA-Based Monitoring

The gateway continuously pings multiple test targets on your primary WAN. It measures latency, packet loss, and connectivity — if any metric falls outside your defined threshold, failover triggers automatically.

Automatic Failover & Failback

When your primary connection recovers, traffic automatically moves back without any manual steps. There's no need to reboot anything, call anyone, or touch a configuration panel.

Load Balancing Mode

For businesses that need maximum throughput, cellular can run simultaneously with your primary connection in a load-balanced configuration — distributing traffic across both links for combined bandwidth.

Dual-SIM Carrier Diversity

The UniFi 5G Max supports two SIM cards simultaneously. Alpine IT configures carrier diversity — typically AT&T and T-Mobile or Verizon — so if one carrier has a local issue, the second automatically takes over.

Cellular as Primary WAN

In locations without reliable fiber or cable infrastructure, 5G cellular can serve as your primary internet connection — not just backup. The U5G Max delivers performance competitive with mid-tier wired service.

Unified Remote Management

All WAN connections — primary and cellular — are managed from the same UniFi dashboard alongside your Wi-Fi, cameras, and access control. One portal, one login for everything.

UniFi Hardware

Purpose-Built Cellular WAN Devices.

Alpine IT installs UniFi cellular hardware — engineered specifically for business WAN applications, not repurposed consumer hotspots.

Primary Recommendation

UniFi 5G Max (U5G-Max)

The flagship cellular WAN device. Supports both 5G Sub-6 and 5G mmWave, plus 4G LTE fallback. Dual nano-SIM slots allow two carrier configurations simultaneously. Designed for outdoor or indoor mounting near a window for maximum signal.

LTE Backup Specialist

UniFi LTE Backup Pro (U-LTE-Backup-Pro)

A dedicated LTE failover device. Specifically engineered as a backup WAN — it only activates when your primary connection fails, keeping cellular data usage and costs minimal while ensuring coverage when you need it most.

The Foundation

UniFi Multi-WAN Gateway

The UniFi Dream Machine Pro or Enterprise Gateway Router is the brain that manages WAN failover. It handles SLA monitoring, policy-based routing, load balancing, and failover logic — integrating your wired ISP and cellular into a single managed WAN.

High Availability

Gateway HA / Shadow Mode

For businesses that need maximum gateway resilience, Alpine IT can configure two gateways in a high-availability pair using UniFi's Shadow Mode (VRRP). If one gateway fails entirely, the secondary takes over without dropping connections.
