Again, Giovanni I'm the position of having to disagree. Wi-Fi and the
companies I offer as examples are not future projects or technologies. They
are currently deployed products with customers.
The 802.11 standards via the IEEE are just as valid as are 3G standards.
The 802.11g standard for Wi-Fi operating in the 2.4 range at max connection
speed of 54MB spec has been released by the IEEE as a standard. Further,
the Wi-Fi Alliance test products for compliance against the standard.
Let me introduce you to some of the devices which are compatible today with
Wi-Fi.

Giovanni, these aren't research laboratories. The above list are companies
with products and customers today. Further, I'm aware of at least one
company in Japan which has deployed Mobile IP on a Wi-Fi network. That's
the beauty of Mobile IP. It's L2 agnostic.
The Japanese WLAN market
http://www.pmn.co.uk/20030304mmj.shtml
Using WLAN for mobile phone communications is looking commercially possible
in Japan, especially following Mitsubishi Electric Corp's release of the
'Mobile IP Talk' handset, which has a slot for a compact flash card where a
PHS or WLAN card can be placed. Although not available until Summer 2003,
Mitsubishi Electric is working on several improvements, but one important
differentiator will be the phone's new power management technology, which
allow for 20 times more standby time than a conventional mobile handset.

Using IPv6, WLAN access speeds in test conditions have been found to run at
11Mbps - regardless of the user's location, according to Nokia . The MIAKO
network runs on the WLAN 802.11b standard utilising 70 base stations around
the city including hotspots at Kyoto Station, the National conference
centre, Kyoto University and several spots outside of the city but within
Kyoto prefecture. The service will be a paid service in order to support the
operational overheads but it will be available for free to handicapped
applications. SCCJ is currently open to application for participants for the
field test click here to apply [Japanese version - not PDA].
