Network Failover
Keep every site online when the primary network connection drops.
Automatic 4G LTE and 5G failover from major carriers, managed in one platform. When the wired connection fails, cellular takes over in seconds. No scramble, no lost revenue, no one running to the closet to reset a router.

The Basics
What is network failover?
Network failover is a backup internet connection that takes over automatically when your primary line goes down. A failover router monitors the wired connection and, the moment it drops, reroutes traffic to 4G LTE or 5G cellular from major carriers. Service stays up, and traffic returns to the primary line once it recovers. Datablaze manages every failover event, SIM, and data plan in one platform.
The Real Cost
Every minute offline has a price.
A dropped connection stops registers, cuts off remote sites, and pulls field teams out of the loop. The wired line is not the problem. Depending on one path to the internet is. Wireless failover gives every location a second path that switches on automatically, so an outage upstream never becomes an outage for your business.
Registers stop
POS terminals, card readers, and ATMs go dark. Every transaction that doesn't ring up is revenue you don't get back.
Remote sites go quiet
Branches, pop-ups, and job sites lose their link to the main office. Work stalls and no one at HQ can see why.
SLAs break
Uptime commitments and customer trust erode with every outage. A second path is far cheaper than the credits you'll owe.
How It Works
Three steps. No one touching a thing.
No dashboards to watch, no switch to flip. The gateway detects the drop, moves traffic to cellular, and restores the primary line on its own.
STEP 01
Detect
The router watches the primary connection around the clock. The moment it degrades or drops, it knows, before most people notice a thing.
STEP 02
Switch
Traffic moves to 4G LTE or 5G cellular from major carriers. The cutover happens in seconds, so sessions stay up and work keeps moving.
STEP 03
Restore
When the primary line returns, traffic shifts back on its own. No manual switch, no field visit, no ticket to close.
Where it Runs
Built for the places you can't afford to lose.
The same failover model protects fixed locations and moving operations. Cellular can back up the primary line or serve as the primary connection outright.
Fixed & Branch Sites
Retail & POS
Keep registers, card readers, and inventory systems live through peak hours.
Convenience stores
Fuel pumps, payments, and back-office systems stay connected when the wired link fails.
Bank branches
Secure, always-on links to the main office for transactions and compliance.
Temporary & pop-up sites
Stand up reliable internet fast where no wired service exists yet.
Mobile & Field
First responders
Constant links for situational awareness and communication in the field.
Transit
Passenger information and predictive maintenance without dead zones.
Fleets
Consistent connectivity keeps vehicles productive and tracked on every route.
Mobile command
Reliable uplinks for emergency operations wherever the unit sets up.
Why Datablaze
A second path, backed by one platform.
Failover is only as good as the network behind it and the visibility on top of it. Datablaze delivers both.
High-speed cellular

Failover, answered.
What is network failover?
Network failover is a backup internet connection that takes over automatically when your primary line goes down. A failover router watches the wired connection, and the moment it drops, traffic reroutes to 4G LTE or 5G cellular from major carriers. When the primary line recovers, traffic shifts back on its own.
How does cellular failover work?
The gateway monitors your primary connection continuously. When it detects a drop or a serious slowdown, it moves traffic to a cellular network through a SIM in the router. The switch is automatic and takes seconds, so most sessions stay live. Once the wired line returns, the router restores it without anyone stepping in.
Can cellular be my primary connection, not just backup?
Yes. Many sites run cellular as the primary connection, especially where wired service is slow, unreliable, or unavailable. The same failover router and SIM handle either role, so you can start with backup and move to cellular-first whenever it makes sense.
How fast does failover happen?
Failover happens in seconds. The router detects the outage and moves traffic to cellular before most sessions time out, so staff and customers rarely notice the switch. Recovery back to the primary line is automatic once the connection stabilizes.
What hardware do I need for network failover?
You need a compatible failover router and a Datablaze SIM. Most locations use equipment they already have, and a specialist can confirm the right fit. The router holds both the wired connection and the cellular SIM, and it manages the switch between them automatically.
How reliable is cellular for critical operations?
4G LTE and 5G coverage from major carriers is built for always-on workloads like payments, point of sale, and remote monitoring. With multi-carrier SIMs, a single site can reach more than one network, so a coverage gap on any one carrier does not take the location offline.
What happens to my connection when the primary line comes back?
When the primary line recovers, the router shifts traffic back to it automatically and returns the cellular connection to standby. There is no manual switch and no field visit. You can see each failover and recovery event in VOYAGER.
How much does network failover cost?
Cost depends on how many sites you cover, the data each one uses, and the hardware already in place. A standby cellular plan is a small fraction of what an hour of downtime costs. Datablaze builds a quote around your sites and can usually turn it around the same week.
Does network failover work across multiple locations?
Yes. The same model scales from one site to thousands, including retail, branch offices, temporary sites, and mobile operations like fleets and first responders. Every location, SIM, and data plan rolls up into a single view in VOYAGER, so you manage them all from one place.
What is the difference between failover and load balancing?
Failover keeps a backup connection on standby and switches to it only when the primary line fails. Load balancing spreads traffic across two or more active connections at once. Many customers use failover for reliability, and some combine both to add capacity and resilience together.
