Definition

Mobility is the capability for a connection, service, or device to remain usable as the endpoint changes location.

Key Points
  • Requires handover, session continuity, and coverage planning.
  • Matters for terrestrial, maritime, aviation, and satellite-connected environments.
  • Can describe user movement, vehicle movement, or device movement.
  • Often depends on service design rather than just radio coverage.
Concept

It describes the operational support needed when endpoints move across cells, beams, access points, or service domains.

Explainer

Mobility is broader than radio handover alone. It includes the service and session behavior needed to keep communication viable while the endpoint moves.
