Since I first got my feet wet in the RF and microwave business about 12 years ago, I've heard the promise of a single phone, single phone number, for each person. I recall spending time in development labs with enthusiastic engineers showing me a cordless DECT phone that showed promise for the beginnings of being a cordless phone in your house, and converting to a wireless phone when you get out of range.
Now it seems that the path to the single phone is to combine cellular service and WiFi. There seems to be plenty of these phones available. I'm wondering, what's the real buzz, do they work well? Better yet, have any of you designed one? If yes, do you wish there had been a better part to get the job done? Click on over to the forum and let us know about your WiFi/cellular design challenges.
