 NEW YORK (AP) - Americans pay on average $50 per month for cell-phone service, yet there are free wireless hotspots in lots of places.
How about using them for your calling instead? I gave three approaches a try, and although none of them is going to make me ditch my cell phone in a hurry, they show that with a little development, Wi-Fi can definitely compete.
Wi-Fi calling isn't exactly new: Wi-Fi telephones and walkie-talkie-like "communicators" have been available for offices and hospitals for years through companies like Vocera Communications Inc. and SpectraLink Corp.
