CDPD Wireless
Here's my configuration. I've used it for about 3+ years:Compaq laptop (I've also used IBM)"Spider II" CDPD card from Enfora (www.enfora.com) Sierra Wireless (www.sierrawireless.com) also makes a good card.CDPD service from AT&T. Other providers are available and will sell you the service and the modem (www.budgetweb.com/cdpd/providers.html). Most providers have a flat rate plan so it does not matter how much/often you use the card. The only catch is that you have to be in a CDPD-enabled area. I've used my card everywhere from Lake Texoma (60 mi north of Dallas), to Houston, Florida, New Jersey, and New York.CDPD is a cellular-based service, so most populated areas with decent cellular coverage will have CDPD.Once the card is installed and configured, it's basically the same as any dialup or broadband internet account (but only at 19.2Kb). You fire up your laptop, start the CDPD modem, and surf or get email. The card is not a big power draw on your laptop, but I normally keep my 12v adapter on my laptop plugged in at all times.Even though we are on an inland lake, I've had great weather radar updates on spring storms that roll in way before alerts came out. Plus, I've been able to work from the boat (to help pay for it!!!).Cap'n D
