Short answer
There is no single best option: the right connectivity depends on your performance requirements, the applications you run and how much downtime the business can tolerate. For most fixed sites FirstNet starts with business fibre as the primary link and adds a diverse backup where downtime costs revenue.
In detail
Each technology solves a different problem:
- Business fibre: the primary medium for most businesses, with high speeds, low latency and stable performance.
- Dedicated Internet Access (DIA): uncontended, symmetric, committed bandwidth for head offices, core sites and hubs.
- Licensed microwave and fixed wireless: fixed-site access where fibre is not feasible, or a backup that does not share fibre's trench.
- LTE/5G: rapid go-live, temporary sites and failover, often live within a few working days.
- LEO satellite: remote sites where no terrestrial option fits, or an independent backup path.
FirstNet starts the design with one question: what happens if your internet is down for two hours, or a full day? Non-critical sites may accept a single link, revenue-impacting sites get a primary plus a diverse backup, and multi-site estates often add SD-WAN across two links per site. Cost is then weighed against business risk rather than access price alone. A FirstNet specialist can assess your sites and recommend the mix.
