Nokia Tests Cellular Wi-Fi Phones

Nokia, the world largest handset maker, has begun testing technology in a Finnish city that lets users to make calls on both cellular and Wi-Fi networks and switch between networks without interruption.

Nokia's new 6136 phone automatically transfers voice or data connections from GSM networks to Wi-Fi when the device recognizes a compatible wireless network, Doug Dawson, a spokesman with Nokia, says. And, vice versa, when users make a call or data transfer via Wi-Fi and step out of the Wi-Fi network's coverage area, the connection is transferred to a GSM link without interruption.

Around 50 people in Oulu, Finland, are testing the new service as part of a two-month pilot initiated by Nokia in cooperation with Finnet and the City of Oulu. The city has been offering free access to Wi-Fi hot spots since last year as part of a project to spur wireless Internet service.
