When your primary internet connection drops, every minute offline costs your business money, productivity, and customer trust. For companies that depend on constant connectivity — from retail locations processing transactions to healthcare offices accessing patient records — even a brief outage can cascade into hours of disruption. Cisco Meraki cellular gateways solve this with always-on 5G and LTE failover that activates automatically, keeping your business running while your ISP sorts out their problems.
“Gartner estimates that the average cost of network downtime for mid-sized businesses exceeds $5,600 per minute. Cellular failover isn’t a luxury — it’s the most cost-effective insurance policy your network can have.”
What Are Cisco Meraki Cellular Gateways?
The Cisco Meraki MG series are cloud-managed cellular gateways that provide primary or backup internet connectivity over 4G LTE and 5G networks. Unlike traditional failover solutions that require complex configurations and manual intervention, Meraki cellular gateways deliver one-click auto-failover managed entirely through the Meraki dashboard — the same single-pane-of-glass interface that manages your entire network.
The current lineup includes models designed for every deployment scenario:
✓ MG52 — Next-generation 5G sub-6 GHz gateway with Cat 20 LTE fallback, delivering up to 2 Gbps download speeds for wired-like performance over cellular
✓ MG21E — Enhanced 4G LTE gateway with external dipole antennas for reliable connectivity in challenging RF environments, supporting up to 300 Mbps
✓ Dual nano-SIM slots — Active/passive SIM profiles with automatic carrier failover when signal degrades or data caps are reached
✓ IP67-rated durability — Built for indoor and outdoor deployments, from server closets to construction sites
How Automatic Failover Actually Works
The beauty of Meraki’s approach is simplicity. When you connect an MG gateway to your Meraki MX security appliance or any existing router, it sits ready as a warm spare. The moment your primary WAN link drops — whether from an ISP outage, a fiber cut, or a local infrastructure failure — the MG gateway activates cellular connectivity and traffic reroutes automatically. No manual switching. No phone calls to IT. No downtime.
The Meraki dashboard monitors everything in real time: signal strength, signal quality, connection status, and data usage across both SIM cards. If one carrier’s signal degrades below your configured threshold, the gateway automatically switches to the second SIM — giving you a failover for your failover. This dual-layer redundancy means your business stays online even when cellular networks themselves experience localized issues.
And because everything is managed through the cloud, your IT team — or your managed IT provider — can monitor and troubleshoot cellular connections across every site from a single dashboard, whether you have two locations or two hundred.
Beyond Backup: Primary Cellular for Pop-Ups, Kiosks, and Remote Sites
While failover is the most common use case, Meraki cellular gateways are increasingly deployed as primary connections. Think about the locations where running fiber or cable isn’t practical or cost-effective:
✓ Pop-up retail stores — Get online in minutes, not weeks, with zero-touch provisioning and 5G speeds
✓ Construction sites — IP67-rated hardware handles dust, moisture, and temperature extremes while providing reliable connectivity for project management tools
✓ Outdoor kiosks and signage — Digital menu boards, self-service kiosks, and wayfinding displays that need always-on connectivity without wired infrastructure
✓ Event venues — Temporary deployments for conferences, festivals, and sporting events where wired connections don’t exist
✓ Fleet vehicles — Mobile connectivity for delivery trucks, emergency vehicles, and mobile offices
With 5G delivering up to 2 Gbps, these deployments aren’t compromising on speed. Your pop-up store can run point-of-sale systems, inventory management, and customer Wi-Fi on a cellular connection that rivals traditional broadband.
Paired with Meraki: A Complete Resilient Network
Cellular gateways don’t work in isolation. The real power comes from integrating them into a full Meraki ecosystem. Pair an MG gateway with Meraki wireless access points for seamless Wi-Fi even during ISP outages. Connect it through a Meraki MX appliance to maintain full security policies, VPN tunnels, and content filtering — even on the cellular backup path. Layer in cloud-managed switches and smart cameras that keep running regardless of which WAN link is active.
For businesses with remote workers, the Meraki Z4C teleworker gateway extends the same resilient connectivity model to home offices, ensuring your distributed team stays productive through any local internet disruption.
Every component reports back to the same cloud dashboard, giving you unified visibility across wired, wireless, and cellular connections — all from one screen.
Getting Started Is Simpler Than You Think
Adding cellular failover to your network doesn’t require a forklift upgrade or a complex migration plan. A Meraki MG gateway plugs into your existing infrastructure as an additional WAN uplink. Zero-touch provisioning means you can ship the device to any site, have someone plug it in and attach the antennas, and configure everything remotely from the dashboard. No on-site IT expertise required.
For businesses already running Meraki, it’s even simpler — the MG gateway appears automatically in your dashboard alongside your existing access points, switches, and security appliances. One network. One dashboard. Always connected.
