5G / LTE Failover & Resilient WAN
Multi-WAN resilience engineered for branch, retail and critical sites.
Jiva Technologies consults, designs, deploys, integrates and supports dual-ISP, cellular 5G / LTE failover and cellular-primary WAN — integrated with SD-WAN for dynamic path selection, automatic failover and clean failback, so business applications remain available when fibre, MPLS or the last mile is impaired.
Dual-ISP, dual-carrier cellular and cellular-primary designs.
Dynamic path selection and automatic failback across sites.
SIMs, data plans, hardware, incidents and lifecycle refresh.
What we deliver
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.
Why teams call us
- Single-carrier sites carry silent risk
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.
Our approach
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.
End-to-End IT Integration and Support
From assessment and solution design through implementation, remediation, ongoing support, and lifecycle optimization.
Fix What's Broken — Remediation Sprints
Wi-Fi dead zones, WAN performance issues, SD-WAN policy drift, or a network you can't see into during incidents? We run fixed-scope networking remediation sprints against a defined outcome.
- LAN/WLAN survey, controller tuning and coverage/roaming fixes
- SD-WAN, MPLS and internet-breakout policy cleanup and QoS tuning
- Observability rollout: flow, telemetry, path-analytics and alert hygiene
Support & Maintenance — AMC-Backed
Keep the network reliable after go-live — firmware, controller hygiene, ISP coordination and vendor-TAC escalation under a Jiva AMC or managed connectivity service.
- L1/L2/L3 support for LAN, Wi-Fi, WAN, SD-WAN and network observability platforms
- Preventive maintenance, firmware and ISP/carrier coordination with SLAs
- Vendor-TAC escalation, licence renewal and network lifecycle refresh
