VOIP Cell Phones Coming Soon
prostoalex writes "Associated Press reports on the latest cell phones with WiFi support demoed at this year's CTIA Wireless 2006 conference. New models fall back to WiFi hotspot when the user is at home, at work, or cellular signal gets too weak. Biggest surprise? The cell phone conversation is not dropped when the switch between cellular network and WiFi hotspot takes place."
For a few months I already own a pda with cell phone and wifi support. I am using a free SIP client to make free unlimited wifi calls with my free sip account. Though the software needs some improvement, it works. However, wifi needs way too much energy. With wifi disabled the battery life is a few days, when enabled it only takes about an hour or two to completely drain the battery, wether I am calling or not! And this is with wifi in 'economy mode', which only makes it usable when reception is very good. Seems to me that for wifi phones to become really popular they have a huge problem to fix.
