NEW YORK (AP) -- Now that some Wi-Fi "hot spots" have grown into broader neighborhood "hot zones," the next wave is waiting: Phones and gear that send conversations over wireless Internet networks -- for free or at a fraction of the cost of traditional calls. Mobile phone maker Motorola Inc. plans to introduce a device that would seamlessly switch calls from cellular networks to cheaper Wi-Fi networks wherever they're available. Discount carrier IDT Corp. is testing consumer Wi-Fi phone service in Newark, N.J. biz.yahoo.com/ap/040509/wi_fi_phones_15.html
I wonder what T-Mobile, who has made a big Hotspot/WiFi push, will do....I guess they would become quite active in this area, especially since they have not made any UMTS announcements.
Cisco has a product that uses WiFi and it looks pretty much like a cellphone. I do have to say though that I didn't like the coverage range. I mean, it died faster than your regular 900Mhz cordless phone! Just walking down the isle it garbles quickly. Sound quality was nice, though. However, due to WiFi's limited range, I expect WiFi to die indoors, meaning it won't spread beyond the walls of buildings. To cover just an airport or a college campus, you need as nearly as many WiFi stations as you need regular cell sites to cover a metro area. WiFi will never become a wide-area solution like WiMAX or 3G technologies. So I wonder why even bother with WiFi phones when we have something much better already?
