3G
The
next generation of wireless technology beyond personal communications services.
The World Administrative Radio Conference assigned
230 megahertz of spectrum at 2 GHz for multimedia 3G networks.
These networks must be able to transmit wireless data at 144 kilobits per second
at mobile user speeds, 384 kbps at pedestrian user speeds and 2 megabits per second
in fixed locations. The International Telecommunication
Union seeks to coordinate 3G standards through its International Mobile Telecommunications-2000
project. In early July, the ITU received
10 proposals for 3G systems and is currently holding a series of meetings to evaluate
the specifications. |
