6. Here's what you need to know about wireless networking, from the standards and technologies to the best products for your home or office.
Today, home networks are used primarily to connect PCs for performing traditional tasks, such as sharing an Internet connection, exchanging files, and printing. But it won't be long before these same networks will be used to transport all types of data, including audio and video, to a wide range of gadgets throughout the home. In fact, this is already becoming a reality. With the right components, you can stream MP3s directly to your stereo and connect your gaming console to your home network.

Adding your stereo to your home network is easy, thanks to a new type of networking device called a digital audio receiver, or DAR. A DAR sends music from your PC to your stereo using any one of a number of networking protocols: wired Ethernet, 802.11g, USB, and/or power-line networking. These vary a great deal in terms of design and features, so it's a good idea to research them all before choosing one.

Gaming consoles
|
|
Some gaming consoles, such as the Microsoft Xbox, come with a built-in Ethernet jack, making them network ready. Not every home is cabled for Ethernet, though. Fortunately, there is an easy way around this that allows you to place your console next to your TV and hook it up to the network without stringing Ethernet cable across the room: just attach a wireless bridge or a wireless Ethernet adapter to the console, and it will play happily with the rest of your network.

Things to consider about wireless bridges
• Is it compatible with other bridges, access points, and routers?
• Does it have a removable antenna or an external connector?
• How many Ethernet ports does it have?
• Does it include both point-to-point and point-to-multipoint modes?
• Is it easy to install? |

Wireless presentation gateways
|
|
Presentation gateways provide a central networking node for the distribution of digital and audio content. You connect the wireless presentation gateway to a projector or a monitor, and, after doing so, anyone can connect wirelessly to the gateway to display images, slide shows, or other content on the screen. Some gateways come with internal memory and allow you to store a presentation directly onto the device so that you can leave your computer at home and take your show on the road.

• How many users can it support?
• How much storage capacity does it have?
• Does it come with a remote control? |
