I'd like to show you the outside packaging?also called the form factor?of two units: Apple's AirPort Extreme Base Stations, and Linksys's Wireless Broadband Router model BEFW11S4. In Chapter 14, "Setting Up Your Access Point," I'll show you how to configure these units in your network.
When I look at the AirPort Extreme Base Station, shown in Figure 13.6, I see something that somehow manages to combine cute with high tech. I don't know whether you've ever seen Woody Allen's movie "Sleeper," but it reminds me of something from that retro-"Back to the Future" film.
The Apple Extreme Base Station may look cute as all get out, but it also has quite a bit of brains and brawn behind that well-designed exterior. For one thing, it runs 802.11g, so it is fast.
You can tell simply by looking at the sockets on the back of the unit that it delivers some nifty features that most other access points don't provide.
If you look at Figure 13.7, you'll see the sockets on the back of the Apple Extreme Base Station.
The Ethernet WAN (or Wide Area Network) port is used to connect to a cable or DSL modem (or, in some cases, to a network connected to the Internet).
tip
The AirPort Extreme Base Station provides a standard antenna connector, so you can add any antenna you'd like. For more information about antennas, see Chapter 17, "Adding Wi-Fi Antennas to Your Network." |
The Ethernet port can be used to connect a wired network "behind" the AirPort Extreme Base Station. You can connect the port to a hub or switch, and then add quite a few wired devices. That way, you wouldn't need a separate router.
The USB printer port provides a way to give all the wireless devices connected via the AirPort Extreme Base Station access to a printer with a USB port.
The antenna for the AirPort Extreme Base Station is sold separately for about $75 at Apple stores. When it is attached to the unit, as shown in Figure 13.8, the range of the AirPort Extreme Base Station is considerably extended.
Linksys's Wireless Broadband Router model BEFW11S4, shown in Figure 13.9, is a pretty typical middle-of-the-road 802.11b access point, which you should be able to buy for a street price of around $50.
Even though it's not as nifty as the AirPort Extreme, there's nothing wrong with this unit. (True, it does run the slower 802.11b protocol rather than 802.11g like the Apple.) If you want to run the faster 802.11g, you can spend a little more money and buy a Linksys model that supports it. (An 802.11g access point and router from Linksys can be had for around $100, as opposed to the AirPort Extreme Base Station for $250 and the 802.11b Wireless Broadband Router for $50.)
I'm including the Linksys here and in the next chapter to show you what the setup and configuration experience will probably be like with good equipment bought where budget is the main consideration.
Note the two antennas on either side of the unit shown in Figure 13.9. Having two antennas like this helps give this unit solid signal strength and range.
The best feature is on the back of the Linksys unit, shown in Figure 13.10.
As you can see in Figure 13.10, you can plug the Linksys Broadband Router into your cable or DSL modem, connect your wired computers to it, use the unit to connect via Wi-Fi to wireless computers, and need no further hardware. With this unit you don't need no stinking router, or even a switch or hub (provided you have four or fewer wire-line computers).
