A prototype of the Wi-Fi phone

A prototype of the Wi-Fi phone, which allows you to talk for free using Skype(TM) off your phone, not your computer was on display. What is interesting about it is that it comes with a small router. If you connect the router to the network at hotels and offices using a LAN cable, you can use this phone without a computer. Moreover, the use of the router has greatly improve the battery life of the phone itself (standby time of 55 hours, talk time of 4.5 hours). Of course you won't need the router if your in an environment where there is wireless LAN.
