Handset manufacturers such as Nokia, Samsung, HTC, iPhone,and even Blackberry are producing powerful WiFi capable handsets. Why use WiFi?

New chip designs are in the works to solve this problem.Second is the perfection of seamlessly switching between the WiFi VoIP phone and the GSM network. Many handsets active on a WiFi network will drop the call once out of signal range. Nokia is the forerunner on having the ability to switch between the two technologies without dropping the call.
