b) Infrastructure Mode

Infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communication between clients passes through an AP.
It doesn't matter if the AP is stand-alone or wired to an Ethernet network.
If used in stand-alone, the AP can extend the range of independent
wireless LANs by acting as a repeater. The image below depicts a
network in infrastructure mode.
