Voice over Wi-Fi

“Today people take laptops to wireless hot spots in coffee bars and airports to check their e-mail messages and to explore the Internet. Soon they may pack a new type of telephone and take it along, too, to make inexpensive calls using those wireless connections. The phones are called voice over Internet protocol over Wi-Fi (or, simply, voice over Wi-Fi) handsets. Like conventional voice over Internet protocol, or VoIP, services, they digitize the voice and send it as data packets over the Internet. But they do it wirelessly, over an 802.11, or Wi-Fi, network. And also like conventional VoIP, the technology may become popular with people who want to economize on their long-distance bills by using Wi-Fi connections when possible."
