Infrastructure networks
On an infrastructure network, devices, such as computers and printers,
communicate through a Wireless Access Point (WAP) . WAPs commonly act as
routers or gateways on small networks.
For example, a simple infrastructure wireless network might consist of a laptop and
a printer communicating through a WAP.
Mixed wired and wireless networks
Wireless devices often exist on a largely wired network.
In this case, a
WAP is connected to the main network by an Ethernet cable plugged
into the WAP's WAN port. The WAP acts as the go-between for the wired devices
and the wireless devices. The wired devices communicate with the WAP over the
Ethernet cable, while the wireless devices communicate with the WAP over radio
waves.
For example, a mixed wired and wireless network may consist of the following:
• Several desktop computers
• A WAP connected to an Ethernet network
• A printer connected wirelessly to the WAP
In order to use the printer, a desktop PC sends a print job over the Ethernet cable
to the WAP. The WAP then wirelessly transmits the print job to the printer.
