問題文
A capture from a busy warehouse channel shows single transmissions which carry many payloads at once. A colleague asks why the radios do this. What is the reason?
選択肢
- Aggregation packs several payloads into one transmission and the clients no longer need to wait for the medium.
- Aggregation packs several payloads into one transmission and the fixed overhead of contention plus headers is then paid once instead of many times.
- Aggregation packs several payloads into one transmission and the radio then uses a higher transmit power for the whole burst of data.
- Aggregation packs several payloads into one transmission and the receiver skips the frame check sequence for the whole burst.
