Wireless networks are growing everywhere; one can find Wi-Fi hotspots at most public places. Packet Tracer has a limited number of wireless devices but provides an unlimited number of possibilities. When configuring a wireless network, one has to consider the physical range of connectivity. Even though it is only a simulator, the physical workspace of Packet Tracer will enable us to test the wireless range of our network using its capability of moving around devices. Towards the end of this chapter, we'll also configure a RADIUS server to provide authentication for our wireless network.
