Nadim Najjar / Original educational work
The sequence, in words
A descriptive summary of the film, not a word-for-word narration transcript.
- The device begins inside the coverage area of the serving cell.
- As it moves, the relative radio conditions of the serving and neighboring cells change.
- A measurement event supports the network decision. A stronger neighboring signal alone is not the whole policy.
- The connection moves to the target cell and the visual completes the conceptual handover.
What to take away
Follow the boundary between an observation and a completed change. A visual sequence makes the mechanism easier to discuss; a real design still needs site-specific engineering, operating procedures and verification.
