One of the things I really like about a PDA with built-in WiFi, is that you can carry it in your pocket, and have it sniff for wireless networks. When travelling, and wanting to avoid the huge costs of cell-phone based connections, or even commercial HotSpot sertvices, this is a nice way to find a place to connect. <\/p>\n

My Palm Tungsten C, will even vibrate in my pocket, when it comes across an open network, thanks to the excellent NetChaser<\/a> software. The problem with that is of course, that WiFi tends to drain the battery of a PDA pretty quickly, and also that the Tungsten C is a bit expensive if all you’re going to use it for is identify networks, before opening up your laptop for some real work \ud83d\ude09<\/p>\n

Enter Kensington<\/a>
\nKensington and their newest product the WiFi Finder<\/a>. It is a small pocket-sized device that has 3 LEDs that will indicate the presence of a wireless network, and show it’s signal strength. Of course, you’d still have to open up your PDA or Laptop to find out whether i is actually possible to connect to the internet through a given wireless network, but it does save you a lot of battery power innthe meantime.<\/p>\n","protected":false},"excerpt":{"rendered":"
