Business Internet
Layer your defenses: UPS battery backup, generator power, and the right wireless failover for your application. Full protection from a 30-minute blip to a week-long outage.
Keeping your internet running during a power outage requires solving two separate problems: keeping your equipment powered, and maintaining a working connection even when local infrastructure is affected.
Power protection comes in three tiers depending on how long the outage lasts. A UPS (Uninterruptible Power Supply) handles short outages — minutes to a few hours. A gas-powered or propane generator extends that to days or weeks. A solar generator or solar-plus-battery system can run indefinitely for critical loads and works without fuel delivery.
Internet backup options vary widely based on your location, application, and budget. Cellular (3G/4G/5G) is the most common choice because cell towers carry their own battery and generator backup. Fixed wireless point-to-point provides business-grade reliability in line-of-sight deployments. Satellite — either low-earth orbit (Starlink) or traditional geostationary (HughesNet, Viasat) — covers areas where no other option reaches.
The right combination depends on your outage risk, downtime tolerance, and what you're keeping online.
Choose based on how long your outages typically last.
The right backup connection depends on where you are and what you need to keep running.
Industrial and institutional power protection follows different standards than residential use. Here is what each sector requires.
Layer your approach: a UPS handles short outages (under 8 hours) automatically. For longer outages, pair it with a gas, propane, or solar generator. A standby generator with an automatic transfer switch gives you full protection with zero manual intervention.
A $60–$100 UPS typically provides 2–4 hours for a modem and router. A $150–$200 unit can extend that to 6–8 hours. Adding a VoIP adapter increases the load and reduces runtime.
A solar generator is a rechargeable battery pack with solar input ports (e.g., EcoFlow Delta Pro, Jackery Explorer 2000). It recharges from solar panels during daylight with no fuel cost. Best for: extended outages, medical devices, off-grid locations, or anyone who wants a fuel-free backup. Not ideal as a primary backup in storm-prone regions without adequate panel capacity.
4G/5G LTE is the best choice — low latency (20–50ms), wide coverage, and cell towers have independent power. Fixed wireless point-to-point is also excellent if line-of-sight is available. Avoid traditional satellite (HughesNet/Viasat) for VoIP — 500ms+ latency makes calls unusable.
Starlink is the top choice for rural areas — 50–200 Mbps with 20–60ms latency. Traditional satellite (HughesNet, Viasat) is a fallback where Starlink is unavailable. Fixed wireless point-to-point works if there is a tower or relay within line of sight.
3G is legacy and being phased out by most US carriers — avoid building new solutions around it. 4G LTE is widely available, reliable, and sufficient for most business applications (50–150 Mbps typical). 5G offers faster speeds and lower latency but coverage is limited to urban and suburban areas. For backup purposes, 4G LTE provides the best balance of coverage and reliability.
A point-to-point (PtP) wireless link uses directional antennas to create a private microwave connection between two locations — typically a rooftop or tower to your building. It bypasses the phone company entirely. Speeds range from 100 Mbps to 10 Gbps. It requires clear line of sight and professional installation, but delivers near-fiber reliability at a fraction of the cost in the right environment.
Without a UPS, your modem and router lose power immediately. With a UPS, they stay on. However, your ISP's local equipment may also be down — especially in major outages. A cellular, fixed wireless, or satellite backup provides a path that operates independently of your primary ISP's infrastructure.
