問題文
Two access points in an office are set to the same 5 GHz channel and their cells overlap. A third source is a nearby video camera on the same frequency. How should these two problems be named?
選択肢
- Both cases are contention because every source on the frequency waits its turn and then sends a frame.
- The two access points create interference on the same channel and the camera creates contention because both sources share the frequency.
- Both cases are interference because the two signals overlap and they share the same part of the band here.
- The two access points create contention on the same channel and the camera creates interference for that whole channel.
