Which floor experienced jitter during streaming live presentations?

• A. Floor 41
• B. Floor 30
• C. Floor 40
• D. Floor 35

Answer: (B)

Jitter is about how much the time between arriving packets varies. In live streaming, smooth playback relies on a steady flow of data; when arrival times swing, the player has to buffer more, which can cause stutters or pauses.

In a multi-floor environment, wireless conditions and traffic load change from floor to floor. The floor that shows jitter is the one where these factors push packet timings to be inconsistent—often due to weaker signal, more interference, or higher device contention. Floor 30 likely had poorer RF conditions or heavier usage, causing more variability in packet delivery and, therefore, noticeable jitter during streaming. The other floors typically have either better signal, fewer competing devices, or shorter paths to the access point, which keeps timing more uniform and reduces jitter.
