問題文
A colleague asks for the radios of a site to be pinned to the densest modulation scheme that the hardware supports so that every client is given the highest rate that the hardware can reach. What happens to the clients that sit away from the units if that request is met?
選択肢
- A dense scheme is picked by the client rather than by the radio of the unit so the request has no effect on any of the links.
- A dense scheme asks the radio of the unit for extra power so the units of the neighbors of the site lose the margin that they had held before the change was made.
- A dense scheme takes more airtime for the same amount of data so the capacity left for the other clients of that channel falls away from the figure that the design assumed.
- A dense scheme holds its states close together so a receiver reads one state as another wherever the level fails to clear the sensitivity for that scheme.
