The backup line that actually takes over when it matters

5G Backup and Failover

An untested backup line fails exactly when you need it, and nobody notices in time. Anexum combines fixed-line and mobile across separate carriers, monitors both paths continuously, and tests failover on a schedule. Your 5G backup proves in testing that it takes over when it matters.

What is 5G Backup and Failover?

A 5G backup reduces outage risk only when the line, router, signal, and failover state are continuously monitored and regularly tested. Anexum plans primary and backup paths independently of any single carrier and defines support through the selected SLA.

Service scope

  • Separate primary and backup carriers
  • LTE/5G router and SIM management
  • Signal and failover-state monitoring
  • Policies for critical traffic
  • Scheduled failover tests

No blind backup path

Signal, router, and failover state are measured before the primary line fails. A weak backup shows up in testing, well ahead of a real incident.

Carrier diversity

Primary and mobile networks can be selected separately according to local coverage.

Controlled operation

Bandwidth and permitted traffic can be aligned with the location design.

Common questions

When does 5G backup make sense?
For locations with high outage costs, temporary construction sites, branches, and critical cloud applications, mobile connectivity can be an economical second access technology.
Does a leased line still need a 5G backup?
A leased line lowers the likelihood of an outage and shortens the repair, but it does not prevent a digger from cutting the building connection. For business-critical sites we combine dedicated access and mobile over a second carrier. When which combination pays off is explained in leased lines for business.
What is monitored?
Possible metrics include reachability, latency, jitter, packet loss, bandwidth, mobile signal, router health, and the active failover path.
What is not promised by default?
Static IP, session preservation, and uninterrupted switching depend on architecture, carriers, and applications. These properties are promised only when technically designed and contractually confirmed.
How is carrier diversity assessed?
Different brand names do not automatically mean separate networks. Where possible, Anexum assesses wholesale access, radio network, building entry, router, power, and regional dependencies.
Which routers can be used?
Depending on requirements, options include Cradlepoint, Cisco, and Teltonika. Selection criteria include WAN options, mobile modem, VPN, routing, remote management, interfaces, and lifecycle.
How often should failover be tested?
Frequency depends on criticality, change rate, and SLA. Each test should check switching, applications, alerting, failback, and documented deviations.
What happens when the 5G signal is weak?
Coverage, signal, and antenna options can be assessed before rollout. If quality is insufficient, alternatives include another carrier, external antennas, LTE instead of 5G, or a different access technology.
How are data volume and costs controlled?
Backup traffic can be prioritized or restricted. The design considers the plan, data allowance, roaming, large updates, and non-critical transfers.

The A1 Outage of 11 August: Calls Down, Data Up

On the afternoon of 11 August, thousands of people across Austria reported problems on the A1 network. Anyone reading the coverage understood "the network is down". Anyone measuring saw something else: data transport largely kept running, while voice, TV and the operator's central services failed. Why that distinction is the most important part of the story for any business running multiple sites.
