Site Diversity
Definition
Site diversity is the deployment of equivalent or complementary functions across separate sites so service can continue when one location is impaired.
Key Points
- It reduces dependence on one physical location.
- It improves resilience against local outages and hazards.
- It is common in satellite ground systems and carrier networks.
- It supports failover and business continuity.
- It usually adds operational and synchronization complexity.
Concept
Site diversity is a practical resilience strategy. Rather than trusting a single facility, the architecture spreads gateways, control points, or service functions across distances that reduce shared-failure risk. The design only works if the diverse sites are truly independent enough to survive the same event.
Explainer
For ConnectedEarth systems, site diversity matters in satellite ground segments, maritime operations, and remote network services. It helps when rain, power loss, fiber cuts, or physical access issues threaten continuity. The trade-off is that the duplicated sites must be synchronized, monitored, and managed well enough that failover does not create a new outage of its own.
