What is SD-WAN and how does it help my business?

SD-WAN (Software-Defined Wide Area Network) uses software to manage traffic across multiple internet connections. It automatically prioritizes critical applications, bonds connections for higher throughput, and fails over to backup links when your primary connection drops. The result is reliable, always-on connectivity without manual intervention.

What happens when my primary internet connection goes down?

With Peplink SD-WAN, failover is automatic and seamless. When your primary WAN link drops, traffic instantly routes through your backup connections, whether that is a second ISP, 5G cellular, or LTE. Active VPN sessions, VoIP calls, and cloud applications continue without interruption.

Can SD-WAN work with cellular connections like 5G and LTE?

Yes. Peplink devices are purpose-built for cellular connectivity. Models like the MAX Transit support multiple SIM cards across different carriers, roof-mounted antennas for optimal signal, and carrier aggregation to combine cellular bands for maximum throughput. Cellular can serve as a primary connection or an always-ready backup.

What Peplink hardware do you recommend for small businesses?

We typically deploy the Peplink MAX Transit (MAX-TST series) for mobile and field operations, and the Balance series for office locations. The right model depends on your connection types, throughput needs, and how many WAN links you need to bond. We assess your environment and recommend the best fit.

What's Included

End-to-end SD-WAN design, deployment, and ongoing management powered by Peplink.

Cellular Failover

Automatic switch to 5G or LTE backup when your primary WAN drops. Zero downtime, zero manual intervention. Your business stays connected while the issue is resolved.

WAN Bonding

Combine multiple connections (fiber, cable, cellular) into a single high-throughput pipe using Peplink SpeedFusion. More bandwidth, more resilience, one logical link.

Real-Time WAN Monitoring

Continuous monitoring of latency, signal quality (RSSI, SINR), packet loss, and throughput across every WAN link. See exactly what each connection is doing at any moment.

SpeedFusion VPN

Encrypted site-to-site tunnels with hot failover across all available WAN links. Traffic stays up even when individual connections go down. Built-in redundancy at the tunnel level.

Mobile & Field Connectivity

Peplink MAX Transit with roof-mounted cellular antennas for vehicles, job sites, and pop-up locations. Reliable connectivity wherever the work happens.

Remote & Rural Connectivity

Primary cellular connectivity for locations where traditional ISP service is unavailable or unreliable. Multi-carrier SIM support ensures the best available signal is always in use.

See It in Action

Real-time visibility into every connection, powered by the Peplink MAX-TST-C5CC.

Multi-WAN Failover at a Glance

The Peplink dashboard shows every WAN link in real time: which connections are active, which are on standby, and how traffic is flowing across each. In this deployment, T-Mobile 5G carries primary traffic through a SpeedFusion tunnel while Verizon LTE and a secondary T-Mobile LTE link stand ready for instant failover.

The MAX-TST-C5CC supports multiple cellular carriers simultaneously with a roof-mounted antenna for optimal signal reception. Combined with SpeedFusion Connect, it delivers enterprise-grade connectivity over consumer-grade media.

Latency Monitoring

Continuous latency tracking across each WAN link. Spikes and degradation are detected instantly, triggering automatic traffic rerouting before users notice.
