Short answer
Not always. Bonding adds resilience and aggregate throughput up to the sum of the links, but per-flow protocol behaviour, the SpeedFusion mode in use and encryption overhead all affect the result. FirstNet sizes the design on your real peak application needs.
In detail: Does Peplink bonding double your internet speed?
Why the result is not simply link A plus link B:
- Aggregate ceiling: the theoretical maximum is the combined capacity of the bonded links.
- Protocol behaviour: individual traffic flows do not always scale evenly across links with different speeds and latency.
- SpeedFusion mode: WAN Smoothing, for example, sends duplicate packets across links to cut loss for real-time traffic, which uses capacity to gain quality.
- Encryption overhead: bonded tunnels carry encryption, which consumes some capacity.
Where bonding clearly helps is continuity. Peplink SpeedFusion treats several WAN links as one virtual link and splits a single flow across them, so if fibre drops, a live call continues on LTE or satellite. Active TCP and UDP sessions, including SIP, RTP and RDP, survive a link cut with sub-second hot failover.
FirstNet's per-site survey covers signal mapping, fibre availability, power and UPS sizing, and hardware is sized by throughput, ports, cellular modems and environment.
