WiFi phones certainly require an Internet connection for you to be able to make calls with them because they use VoIP technology (Voice over Internet Protocol). Netgear's Skype phone or any other Wifi phone basically lets you use an Internet based phone service without a computer or a laptop. To make calls using the WiFi feature of any phone you need to have an Internet connection as well as a wireless modem or router to which the phone can connect wirelessly. These phones are rarely available in India but they cost much lesser than $500. These days you can also use WiFi on certain mobile phones which lets you browse the Internet as well as make calls using the Internet instead of your GSM network.
Wi-Fi (pronounced wye-fye, IPA: /ˈwaɪfaɪ/), is a wireless technology brand owned by the Wi-Fi Alliance intended to improve the interoperability of wireless local area network products based on the IEEE 802.11 standards. Common applications for Wi-Fi include Internet and VoIP phone access, gaming, and network connectivity for consumer electronics such as televisions, DVD players, and digital cameras. ......................v
yes, it can work. The interface softwares like Skype will convey your calls over the Net. Wifi hot spots or home/office network having wifi modem for internet connection could be utilised for this. GSM phones like Nokia N95 or N81 can also be used as wifi phones by downloading software from www.fring.com, which facilitates skype/google talk etc.
