Worldwide, consumer VoIP subscribers using wireless IP Phones
will grow from 2% currently to 73% in 2009.
By 2009, over 66 million cellular/Wi-Fi handset will be in
operation.
By 2009, WLANs will be deployed in 57% of small businesses,
62% of medium sized businesses, and 72% of large enterprises
In 2004, worldwide revenue from dual-mode handsets hit $6.7m
and from all Wi-Fi VoIP handsets totalled $54.7m
The number of enterprises that deploy VoIP over WLAN will triple
during the next two years. Today, 10 percent of North American
enterprises utilize VoIP over WLANs. Analysts expects that
percentage to increase to 31 percent by 2007.
The WiFi market in the Asia-Pacific region will grow to $1.29
billion in 2010, up from $213.2 million in 2004, says a recent
analysts study. Wireless service providers in South Korea, Taiwan,
Japan and China expanded their hotspot coverage, and they are
