Nowadays, everything should be wireless, right? For iPod users, wireless technology finally arrives with Silex' WiDock, an iPod dock, using Apple's Universal design, that synchronises your iPod with your computer over a wireless network.
Designed to be used in your home entertainment centre, the Silex WiDock includes both audio and video outputs and charges your iPod. But it's the Silex WiDock's ability to free you of the need to move your iPod between your living room and your desktop that makes the product unique, although it's not without limitations.
The Silex WiDock is light and compact, so it should be easy for you to choose a spot that best suits your home entertainment system. Its design is simple: on the back of the WiDock you'll find a 1/8in stereo minijack for audio output and an S-video output; on the front, you'll find a "Link" button you press to sync your iPod.
But before you can take advantage of the Silex WiDock's wireless capabilities, you must first connect the dock to an 802.11b- or 802.11g-compatible router via an ethernet cable. (Although the WiDock will work with 802.11n routers that support at least 802.11g, you won't see 802.11n speeds. Silex told us that the company is currently investigating 802.11n compatibility.)
Note that you must connect the ethernet cable to the Silex WiDock before plugging in the WiDock's power cord; if you do this the other way around, the Silex WiDock will attempt to make a wireless connection without the proper configurations.
After connecting the Silex WiDock, you run a setup utility, provided on the included software disc, on your PC (Macs work just fine). The Silex WiDock software should automatically detect the dock's ethernet address over your local network (if it doesn't, you didn't connect the dock properly).
The software will then prompt you to choose between AdHoc and Infrastructure modes (most users will probably choose Infrastructure) and enter your network information, such as your username, password, and security encryption mode. The WiDock works with WEP, WPA, and WPA2 security. (If you've got a wired network connection near your entertainment center, you can instead opt to forego the wireless connection and use ethernet permanently.)
The final step in the setup process is to install, on your computer, an included utility called SX Virtual Link. With this done, you can now unplug the ethernet cable from the dock. After you press, hold, and release the "Link" button, a white LED light will flash, indicating that your iPod has begun synching with your computer wirelessly. The iPod will appear in iTunes just as if you'd connected it directly to your computer, and the Do Not Disconnect message will be displayed on the iPod's screen until synching is complete.
Synching your iPod with iTunes via the Silex WiDock is clearly slower than synching over a direct USB connection. On our 2.16GHz Core Duo MacBook Pro, it took us 2 minutes and 17 seconds to transfer 110MB worth of MP4 video files to my iPod wirelessly via the WiDock over an 802.11g network; it took 1 minute and 6 seconds to transfer 32MB worth of AAC audio files. Over a direct USB 2.0 connection, the same transfers took 32 seconds and 27 seconds, respectively.
But in our opinion, the convenience of circumventing the USB cable is worth the loss in speed. Although if you're synching your entire iTunes library to your iPod - for example, to restore the iPod or if you get a new one - we do recommend reverting to the standard USB connection for the initial sync, and then performing updates wirelessly.
