What does it mean for a wireless network to be operating in "infrastructure mode"? If the network is not in infrastructure mode, what mode of operation is it in, and what is the difference between that mode of operation and infrastructure mode?
If a node has a wireless connection to the Internet, does that node have to be mobile? Please explain your response.
