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
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.
