問題文
A school needs to link a sports pavilion which has no cabling to the main building 300 m away. Only two fixed points are involved and both have power. Which 802.11 use case fits this requirement?
選択肢
- A wireless mesh with several hops because one link falls short of the distance involved at the school.
- A peer to peer link between two laptops because a direct connection is the simplest way to move traffic across the field.
- An extended service set across both buildings because the pavilion needs the same network name as the main building for its own clients as well.
- A wireless bridge between the two buildings because the requirement is a fixed link rather than access for the clients of the pavilion.
