Nokia unveils wi-fi phone for mass market
The world’s largest mobile handset manufacturer, Nokia, on Monday unveiled a mass-market phone capable of switching between wi-fi and GSM. The N6136 handset, launched at the 3GSM World Congress in Barcelona, is a UMA device that will let users make voice over IP (VoIP) calls when the phone detects a wi-fi hotspot. It is thought the emergence of such devices will encourage operators to roll-out high-bandwidth services: wi-fi, in theory, can support speeds of up to 50Mbps.”Internet voice is going mobile,” said Jorma Ollila, Nokia’s chief executive. “UMA gives users an alternative to PC-based VoIP,” he added.
