A Voice over WiFi technology that becomes available when you enter a hotspot location was announced by a Sweedish firm with the concept behind it called “context aware.”
The idea is simple. When you enter a hotspot, part of the authentication includes the installation of VoWiFi/VoIP software.
How this works and what corporate IT professionals concerned about security will say is a question in my mind, but this solution seems to be one more indicator that VoIP at WiFi hotspots is on its way to a laptop and PDA near you.
