Samsung has demonstrated wireless technology that delivers 1Gbit/s to stationary clients, and 100 Mbit/s to clients moving at up to 70 miles per hour.

In the demo, a bus travelled at 37 miles per hour while the technology delivered video on demand, a live broadcast and Internet access simultaneously. The press release did not specify how it was achieved.

The company has promised the technology - in which it has invested $100 million - will be in handsets by the end of 2008, and in commercial services by 2010, but it is not clear how it will be offered through products and standards. The quoted speeds are roughly 50 times greater than those of mobile WiMax.

Samsung also claimed 3.5Gbit/s to a device moving at 5km/hour in a lab test.
