Samsung shows superfast Wimax

MP3 music fille downloads to take 1 second

Samsung Electronics this week will demonstrate a version of WiMax that can transport data at double the speed of current systems at the 3GSM trade show in Barcelona, Spain, it said Monday.

The Mobile WiMax Wave 2 system uses Mimo (multiple input multiple output) technology and smart antennas to achieve speeds of around 34Mbps downstream from the network to the user and about 8Mbps in the opposite direction, the company said. Mimo involves sending data using multiple antennas to increase the total data throughput.

At those speeds it's possible to download an MP3 music file in about one second and a full CD of data in less than three minutes, said Samsung.

A commercial service based on the technology on show in Barcelona is planned by Sprint Nextel in the US later this year. The carrier will use Mobile WiMax to supplement its 3G (third-generation) mobile service and plans to reach 100 million US residents with the new network by the end of 2008.

Before that service can be used, terminals compatible with the network are needed. At 3GSM Samsung will also be showing a chipset compatible with the technology that can be integrated into devices. Competitors have also been showing similar chips recently. On Monday NXP Semiconductors and Israel's Runcom Technologies said they also plan to offer a chipset compatible with the Wave 2 system.
