Short answer
LEO is independent of mobile towers, more predictable where cellular coverage is rural or unstable, and better suited to mission-critical uptime, while LTE/5G can be lower cost for light use or urban failover where coverage is strong. Many critical sites use both alongside fibre, with SD-WAN steering traffic between them.
In detail
How to decide:
- Coverage: LTE/5G needs usable signal from a mobile network; LEO needs a clear view of the sky.
- Independence: LEO does not rely on terrestrial fibre or mobile towers; LTE/5G is unaffected by fibre cuts but can be affected by tower power outages.
- Consistency: LEO gives a consistent service profile across ATMs, point-of-sale sites, clinics and branches; LTE/5G is best-effort and varies with network load.
- Speed to deploy: LTE/5G is often live within a few working days; LEO is generally faster than a new fibre build.
- Service levels: LTE/5G has no fixed uptime SLA.
For remote sites with rural or unstable cellular coverage, LEO is usually the more dependable choice. For urban branches with strong signal, LTE/5G is a cost-effective fibre backup. Where both are available, bonding them with Peplink or steering them with SD-WAN adds a further layer of resilience.
