Seamless roaming for GSM / WLAN / Bluetooth
===========================================

:Description:
    Following articles on Slashdot and Heise, the new standard UMA (Unlicensed
    Mobile Access) will allow seamless roaming between the wireless standards
    GSM, WLAN (WiFi) and Bluetooth.

This is a huge benefit, in my eyes and a huge shot against UMTS (which is IMHO
really senseless in times of WiFi). A new generation of mobile devices can
make heavy usage of UMA. I imagine a mobile device, which uses GSM by default
(since it's mostly everywhere available), switches to Bluetooth / WiFi at your
home, to connect you through your local phone device, or to the WiFi of a
public hotspot, if available, to communicate e.g. by VoIP.

A nice dream...
