Getting carded: SD Wi-Fi cards bring your handheld up to speed

Entrepreneur, July, 2005 by Mike Hogan

If you haven't purchased one of the latest and greatest multi wireless option handhelds, you might find your current device a little lacking. Fortunately, there are options for bringing your handheld up to wireless speed without getting a whole new device.

It's time to put a spare expansion slot to work. Wi-Fi is your best bet to boost productivity and get the most out of your PDA when you're on the road. Wi-Fi cards built for CompactFlash slots have been out awhile. What's newer are SD Wi-Fi cards. Many Pocket PCs and some Palms are equipped with SD expansion slots to handle these tiny add-ons. The convenience factor is high for such small and light options.

Some Wi-Fi card manufacturers to check into include Belkin (www.belkin.com), SanDisk (www.sandisk.com) and Socket Communications (www.socketcom.com). Most gear-makers like Netgear and Linksys have Compact-Flash options, but look for more SD cards to reach the market as the year continues. Some handheld-makers, like PalmOne (www.palmone.com), have their own branded offerings. Look for a low-power card to maximize battery life. The cost of adding Wi-Fi to your handheld can range from $60 to $150. The opportunity to leave your laptop behind on business trips or boost your productivity around the office is priceless.
