73% of residential VOIP subscribers to use wireless VOIP phones by 2009

In both business and consumer markets, widespread adoption of Voice over Internet Protocol (VoIP) depends on the availability of wireless VoIP handsets, reports In-Stat. Dual-mode cellular/WiFi handsets will be the key driver to mass consumer adoption of VoIP, the high-tech market research firm says. By 2009, In-Stat forecasts that over 66 mln cellular/WiFi handsets will be in operation. Worldwide, consumer VoIP subscribers using wireless IP phones will grow from 2% currently to 73% in 2009. Based on competition from mobile carriers without wireline operations, Europe will be the largest initial market for dual-mode smartphones. While mass production of dual-mode sets is not scheduled until 2007, an In-Stat market survey found that over 80% of businesses have an interest in the technology.
