    Answer: B

    co-channel interference is interference resulting from two or more simultaneous transmissions on the same channel.

    I'll go with B as well.

    It sounds right, and Si's statement looks good enough for me.

    Answer: B

    You are all far too brilliant. The correct answer is indeed B. Adjacent interference would be caused by two APs located near each other physically that were set to use adjacent channel numbers such as 1 and 2 or 6 and 7. Channel reuse is when you set up a group of APs to cover an area for roaming. Two non-overlapping AP cells could use the same channel number with no interference. Narrowband interference is caused by a device such as Bluetooth that transmits in the narrow rather than the spread spectrum band. It would block part of a channel or a full channel at most. Good job, gang.

    More tomorrow.
