01 / The engineering trade-offs
Three paths. Different strengths.
Planning ranges, not carrier promises.
Match the link to the workload.
| Design parameter | LEO satellite | GEO VSAT | Fibre access |
|---|---|---|---|
| Example throughput envelope | 50–300 Mbps down | 5–100+ Mbps down | 100 Mbps–10 Gbps |
| Illustrative RTT | 25–100+ ms | 550–750+ ms | 2–30+ ms locally |
| Availability / SLA | Plan-dependent; check exclusions | Managed contract; specify CIR | Best effort or enterprise SLA |
| CAPEX drivers | Terminal, mount, clear sky | RF chain, dish, commissioning | Drop / trenching / optical handoff |
| OPEX drivers | Priority data, power, support | Committed capacity, support | Port rate, access, route diversity |
| Best-fit constraint | Fast access beyond the fibre edge | Managed capacity over wide areas | Stable high-capacity fixed sites |
Ranges illustrate engineering scenarios and overlap; they are neither measured benchmarks nor a purchasing specification. Actual performance, upload capacity and cost depend on location, equipment and contract. Read the methodology.
02 / The field library
Know the system.
Build the right connection.
Practical diagrams. Clear trade-offs.
Regional context for every guide.
Australia + Germany · two regional perspectives, one connected infrastructure.
