What’s the best Wi-Fi phone?
With municipal Wi-Fi taking off and startups distributing free wireless routers for those willing to share their Internet connections, Wi-Fi phones or hybrid phones with both cellular and Wi-Fi access, are attracting interest. Dr. Dobb’s Journal runs a review of 6 wireless phone devices available on the market today. The cheapest ones start around $80, but lock you into T-Mobile branded hotspots. The more expensive ones, Sony Mylo in particular, offer support for 3rd party clients, such as Skype, GTalk and Yahoo! Messenger:
None of the VoIP services running on Wi-Fi phones currently support emergency calling such as E911, which makes having a Wi-Fi phone as your only phone service a risky proposition. Vonage provides a valuable service, though; if 911 is dialed from one of the Wi-Fi phones using its service, the call will be answered by a Vonage emergency call center, which will help contact the appropriate local emergency resources. Because of the power requirements of including a Wi-Fi radio in phones, these first-generation Wi-Fi phones can drain a battery in standby mode in just a day, and offer only a couple of hours of talk time. Some power-saving advancements are being made, such as technology that allows certain devices to lower their power consumption when not actively making calls, but things will need to come a long way before Wi-Fi phones can deliver the days of standby and hours of talk time taken for granted with traditional cell phones.
