Yes, Cingular, Verizon, Sprint all offer a wireless card. I have seen Verizon offer "broadband" service via a wireless card but realize that the speed is very dependent on signal strength/distance to a tower etc.
What I want to know is if anyone is knowledgable regarding the different technology each company is using and which is the most developed.
As far as wireless networking goes, I am using the Belkin Pre-N which has proven to me to be faster/more reliable than my Linksys Wireless G. The Linksys was ok within 50 feet but cut out quick after that. The Pre-N hits well everywhere in my house except in one end. (Long twisty hallway in a 4000 sq. ft. house, router is at the opposite end of house and upstairs) I'll post questions related to home networking in the appropriate forum. Thanks for any and all input on my original question. Dean
