Short answer
Choose SD-WAN for application-aware, policy-based control across many sites, with QoS and security policy. Choose Peplink SpeedFusion bonding when a single live call or RDP session must survive a link cut without dropping, because it bonds links at packet level.
In detail: FirstNet SD-WAN vs Peplink bonding: which to choose?
How to choose:
- SD-WAN: policy-driven control across many sites, application-aware steering, QoS and integrated security, including phased migration away from MPLS.
- Peplink bonding: when live sessions such as voice, video or RDP must not drop, because sub-second hot failover keeps active TCP and UDP sessions running.
- Peplink for rugged and mobile use: vehicles, broadcast, mining and pop-up sites, using MAX series hardware and bonded cellular modems.
- Peplink for noisy links: Forward Error Correction and WAN Smoothing protect real-time traffic.
Both need at least two links per site, and FirstNet can supply the underlays for either: fibre, DIA, LTE/5G, microwave and LEO satellite. Peplink is itself an SD-WAN edge; the difference is that most SD-WAN keeps each session on one link, while SpeedFusion splits a single flow across links. FirstNet can recommend the right approach after a site survey.
