Instead of using cables to create a network, AirPort uses wireless local area network (WLAN) technology to provide wireless communication between computers. Through a wireless network you can access the Internet, share files, play multiplayer games, and more. If you have an AirPort Express and use AirPort 4. 0 or later, you can play iTunes music through remote speakers using AirTunes. Using AirPort technology, you can: · Create a wireless network in your home or school using an AirPort Extreme Base Station or AirPort Express, then connect to the Internet and share the connection among several computers simultaneously. [. . . ] To use the base station in an air-handling space above suspended ceilings, you must connect the Ethernet WAN port to an 802. 3af-compliant PSE with a plenum-rated Ethernet cable. You cannot use the AC power adapter to power a base station installed in an air-handling space. Do not connect an external antenna to a base station mounted in an air-handling space. What It Looks Like AirPort Extreme Base Stations AC power outlet To Network 802. 3af-compliant Power Sourcing Equipment (PSE) Plenum-rated Ethernet cables 40 Chapter 3 AirPort Network Designs How It Works · The AirPort Extreme Base Station uses your Ethernet network to communicate with the Internet and receives power through the Ethernet WAN port ( ). · AirPort clients access the Internet and the Ethernet network through the AirPort Extreme Base Station. Note: An AirPort Extreme Base Station that supports PoE is set up by default to act as a bridge, and the "Share a single IP address (using DHCP & NAT)" option is not selected. Use the Network pane of AirPort Admin Utility if you want to select the "Share a single IP address (using DHCP & NAT)" option. What You Need for a Power Over Ethernet (PoE) Connection Components AirPort Extreme Base Station or multiple base stations that support PoE 802. 3af-compliant Power Sourcing Equipment (PSE) Plenum-rated Ethernet cables If you are mounting the base station in the air-handling space above a suspended ceiling, you need to use plenum-rated Ethernet cables. Check Comments What to Do Follow the instructions in the previous section, "You're Using an Existing Ethernet Network" on page 32, to set up the AirPort network. Setting Advanced Options Use AirPort Admin Utility to adjust optional advanced base station settings. Using the AirPort Extreme Base Station or AirPort Express as a Bridge You can turn off the base station's Internet sharing features (which provide IP addresses to AirPort computers using DHCP or NAT) to allow bridging between the network's wireless and wired computers. With bridging turned on, AirPort computers have access to all services on the Ethernet network, and the base station does not provide Internet sharing services. Using the base station as a bridge can be a way to address incompatibilities between the base station's Internet sharing features and your ISP's connection method. To use the base station as a bridge, all AirPort and Ethernet computers need to have IP addresses set manually and use the same subnet mask. Chapter 3 AirPort Network Designs 41 To set up the base station as a bridge: 1 Open AirPort Admin Utility and open your base station's configuration. 3 Deselect the "Distribute IP addresses" checkbox. Connecting Additional Base Stations to Your AirPort Network You can connect additional AirPort Extreme or AirPort Express Base Stations to extend the range of your wireless network. You can connect the base stations wirelessly or, if you are using AirPort Extreme Base Stations, using Ethernet. A network with base stations connected using Ethernet is known as a roaming network. Connecting base stations wirelessly creates what is known as a Wireless Distribution System (WDS). Setting Up Roaming Multiple AirPort Extreme Base Stations can be set up to create a single wireless network. Client computers can move from base station to base station with no interruption in service (a process known as roaming). To set up roaming: 1 Connect all of the AirPort Extreme Base Stations to the same subnet on your Ethernet network. 3 Give each base station the same network name and password. 4 Set up the base stations as bridges, following the instructions in the previous section. If you want one AirPort Extreme Base Station to assign IP addresses using DHCP, also do the following: 1 Set up one base station to act as the DHCP server. [. . . ] The base station can provide IP services like DHCP and NAT over this interface. The base station cannot use the AirPort interface to establish a connection with the Internet. · Modem (W) interface The modem interface is used to establish PPP connections to the Internet. These connections provide IP services to the base station. [. . . ]
