Monitoring mode gets frames from more than one channel!

Sorry, when i said scanning i meant active.

But even passive scanning requires you to go through all channels, and 
usually monitor mode is used to capture the packets on particular 
channels, so no channels changing and if you do change channels to get 
beacon frames on other channels then you would miss frames from your 
original channel where you want to monitor!
