Is 5G reliable enough as a failover WAN?

Modern 5G Sub-6 and mid-band deliver fibre-comparable throughput with SD-WAN failover. For business-critical sites we recommend dual-carrier SIMs, antenna diversity and validation during commissioning to confirm performance against the design specification.

How is failover monitored and reported?

SD-WAN and observability telemetry captures every failover event — timestamp, duration, root cause and path used — surfaced in the operations portal and executive dashboards, with monthly SLA and RFO reporting under the managed service.

Can 5G act as the primary WAN for smaller sites?

Yes. Many retail, pop-up and micro-branch sites now operate cellular-primary with fibre-secondary, or dual-carrier cellular, especially where fibre install lead times or costs are prohibitive.

Which cellular edge platforms do you work with?

Multi-vendor across Cradlepoint E-Series, Cisco Catalyst / Industrial Routers, Peplink, Fortinet FortiExtender, Digi and Sierra Wireless — integrated with our supported SD-WAN and SASE platforms.

Do you manage the SIMs, data plans and lifecycle?

Yes. Managed connectivity covers pooled and per-site data plans across major carriers, usage alerting, overage protection, consolidated billing, SIM lifecycle and hardware refresh under a single service agreement.

5G / LTE Failover & Resilient WAN

Scope in detail

Multi-WAN & Dual-ISP Design
Dual-ISP internet edge with carrier diversity, LACP, BGP peering and route health monitoring — engineered to reduce single points of failure at every branch, retail site and data-centre edge.
5G & LTE Always-On Failover
Cellular 5G Sub-6, mid-band and LTE as an always-on secondary WAN path — integrated with SD-WAN so critical applications, POS and unified communications remain available when fibre or MPLS is impaired.
Dynamic Path Selection & Automatic Failback
Application-aware SD-WAN policy that selects an appropriate transport in real time and fails back cleanly when the primary link is healthy — with event logging, alerting and monthly Reason-for-Outage (RFO) reporting under managed operations.
Branch, Retail & Critical-Site Uptime
Retail, branch, healthcare and manufacturing sites protected by dual-carrier SIMs, antenna diversity and monitored data plans — with business-continuity SLAs measured against agreed availability targets.
Pop-Up, Temporary & Disaster-Recovery Sites
Event, construction and disaster-recovery locations brought online with cellular-first WAN edge — bypassing carrier lead times while maintaining enterprise policy, security and observability.
IoT & Mobility Backhaul
Vehicle fleets, kiosks, digital signage and industrial IoT connected on managed cellular — with per-device policy, encrypted overlays, MFA and centralised monitoring integrated into the wider enterprise network.
Cellular Hardware & Antenna Design
Multi-vendor cellular edge engineered on Cradlepoint, Cisco Industrial Routers, Peplink, Fortinet FortiExtender, Digi and Sierra Wireless — with RF surveys, antenna selection and outdoor / harsh-environment enclosures where required.
Managed SIMs, Data Plans & Operations
Consulting, procurement, deployment, integration and managed operations for cellular WAN — pooled and per-site data plans across major carriers, usage alerting, overage protection, consolidated billing and lifecycle refresh under an agreed service schedule.

Availability risks in single-path WAN

Branch sites depend on a single path
Critical branches, retail and healthcare sites rely on one ISP and one path, so a single carrier or last-mile event takes services offline until manual intervention.
Cellular has been used only as a last resort
LTE modems sit in cupboards without SD-WAN integration, tested failover or antenna design, and are not part of the operational playbook when incidents occur.
Pop-up and temporary sites wait weeks for fibre
New locations, campaigns, disaster-recovery moves and construction sites are gated by carrier lead times that do not match the business timeline.
SIM and data-plan estates are unmanaged
Contracts, usage, overage, hardware refresh and end-of-life status for SIMs and cellular routers live across spreadsheets and multiple carrier portals.

Resilience delivery lifecycle

A resilience-focused WAN lifecycle covering site-criticality assessment, multi-transport design, validated failover and managed cellular operations.

Assess
Review site criticality, current WAN topology, carrier estate, incident history and business-continuity targets across branch, retail and critical sites.
Design
Produce a multi-WAN, dual-carrier cellular and cellular-primary architecture with SD-WAN policy, antenna specification and monitoring integration.
Implement
Deploy cellular edge hardware, integrate with SD-WAN and observability, validate failover and failback and hand over documented runbooks.
Operate & Report
Manage SIMs, data plans, incidents and lifecycle refresh under an agreed schedule, with monthly SLA and RFO reporting where included in scope.
