Mobile Auto-Failover — Always-On Connectivity When Primary Links Fail
Auto-failover automatically switches connectivity to a backup cellular or satellite link when the primary WAN connection fails — maintaining business continuity for branch offices, retail locations, field sites, and mobile operations that can't tolerate internet outages.
What RLM Delivers on Mobile Auto-Failover
Single-link WAN connectivity creates operational risk that few businesses can afford. Cellular failover provides the secondary path that activates within seconds of primary link failure — transparently maintaining VPN tunnels, cloud application access, and critical communications while the primary link is restored. RLM advises on failover architecture, router and gateway selection, and the detection and recovery logic that minimizes failover impact.
How We Approach Mobile Auto-Failover
Our Mobile Auto-Failover process, end to end: current state, market evaluation, commercial terms, and implementation support.
Failover Requirements Assessment
We assess your failover requirements by site — documenting business processes affected by outages, acceptable downtime thresholds, bandwidth requirements during failover, and the applications that must remain accessible during primary link failure.
Failover Architecture Design
We design the failover architecture — primary/secondary link assignment, detection mechanisms (BFD, keepalives, SLA probes), failover trigger thresholds, and the recovery logic that restores primary link traffic without disrupting active sessions.
Router & Gateway Selection
We evaluate failover-capable routers and SD-WAN gateways — Cradlepoint, Digi, Peplink, Cisco, Meraki — against your site types, cellular carrier compatibility, management model, and the remote management capability needed to operate distributed failover infrastructure.
Cellular Carrier Selection for Failover
We select cellular carriers for the failover path based on coverage at each site location — evaluating signal strength, carrier diversity from the primary link, and the data plan structure optimized for standby-mode cellular.
Mobile Auto-Failover Evaluation Criteria
Our Mobile Auto-Failover process, end to end: current state, market evaluation, commercial terms, and implementation support.
Failover Detection Speed
The speed of failover detection determines how long applications experience disruption. Evaluate detection mechanisms and typical failover times under different failure modes — link down vs. degraded performance.
BGP & VPN Tunnel Recovery
VPN tunnels and BGP sessions interrupted by failover don't always recover automatically. Evaluate the VPN and routing recovery behavior during and after failover events.
Cellular Data Costs During Failover
Failover events that transfer significant data to cellular can create unexpected carrier costs. Evaluate data plan sizing for failover scenarios and whether application traffic should be prioritized or throttled during failover.
Multi-Site Failover Management
Organizations with many sites need centralized visibility into failover events. Evaluate the management platform that provides real-time failover alerts, event logging, and the diagnostic tools that accelerate primary link restoration.
Failover Testing
Untested failover systems often fail when needed. Evaluate the scheduled failover testing process — simulating primary link failure to validate detection, transition, and recovery behavior before a real outage occurs.
"RLM helped us rationalize our mobile fleet across four carriers and cut our monthly spend by 31%. They handled the whole transition — we didn't lose a single device."
We stay involved through implementation, because selection is the easy half.
Where This Matters Most
Sector-specific considerations we see repeatedly in mobility engagements.
