Cellular Technology

"Over the next few years, companies will start selling dual-mode cellular/Wi-Fi phones. The phones will be able to make voice calls either on a cellular network, or by connecting via Wi-Fi wireless Internet to make calls using VoIP (a.k.a. Voice over Internet Protocol).

Cell-Fi, man. Dig it.

When in range of Wi-Fi — in your office, home, Starbucks — the phone will make calls using VoIP, which should be cheaper and better quality than a typical cell call. When there's no Wi-Fi, the phone will switch to the cell network."
