Mobile WiMAX WAVE 2 : 3GSM Samsung fait la demonstration de son Mobile WiMAX WAVE 2

Alors oui, tout le monde ne possède pas encore la 3G ni même la 3.5G avec le HSDPA, mais cela n’empêche pas les constructeurs de toujours vouloir aller plus loin. Tous les Geeks le savent, le « futur » en matière de communication sans fil passera par la case WiMAX et hier nous vous présentions 3 produits Samsung utilisant cette technologie. Mais si encore peu d’entre nous ont eu la réelle chance de voir ce que cela donne en live, Samsung se propose de faire une démonstration à toutes les personnes visitant le 3GSM de ce que le WiMAX est, et plus exactement leur WiMAX WAVE 2 qui propose une vitesse de 40Mbps en download et 12MBps en upload, ce qui donne par exemple un download en 2 minutes et 45 sec pour un film de 700MB… Va en falloir de l’espace disque sur son PDA pour faire ce genre de truc.






BARCELONA, Feb 13 -- Samsung Electronics Co., LTD, a leading provider of telecommunications network, demonstrated its newest Mobile WiMAX technology, ‘Mobile WiMAX WAVE 2’ at 3GSM World Congress 2007, Barcelona, Spain.

‘Mobile WiMAX Wave 2’ which supports Multi Input Multi Output (MIMO) and Smart Antenna is a next generation mobile telecommunications technology created by the combination of Mobile WiMAX and 4G technology. It can realize 40 Mbps download and 12 Mbps upload transmission speeds in maximum.

The demonstration in Samsung booth, Samsung Electronics used ‘Mobile WiMAX Wave 2’ systems and terminals to successfully demonstrate high-speed transmission of data at 34 Mbps for downloading and 8 Mbps for uploading. At this download speed allows the users to download MP3 music files (3 MB) in 0.7 second and a movie (700 MB) in 2 minutes and 45seconds.

At 3GSM, Samsung will showcase Spatial Multiplexing (SM) function of MIMO technology through 4 Field-Programmable Gate Array (FPGA) terminals. Operators can reduce CAPEX and OPEX, through the MIMO and Smart Antenna technology which increase the data through put and cell coverage compared to existing technology Single Input Single Output (SISO). Moreover, ‘Mobile WiMAX Wave 2’ can upgrade current platform to MIMO and Smart Antenna technology with simple software upgrade.

In addition to the demonstration, Samsung also introduced its in-house-developed core chip for ‘Mobile WiMAX Wave 2’, attracting interest from the global telecommunications industry including mobile telecommunications operators. ‘Mobile WiMAX Wave 2’ is to be deployed by Sprint and other operators by late this year.

Geesung Choi, President and CEO of Samsung’s Telecommunications Network business said, “We will continue to develop innovative technologies such as Mobile WiMAX Wave 2 and will accelerate the commercialization of Mobile WiMAX in global market.”

Samsung Electronics is now pursuing Mobile WiMAX businesses with 35 operators in 23 countries globally. The company has already concluded commercialization contracts or is implementing pilot service with nine operators in seven countries including the US, Europe, and South America.

Mobile WiMAX Wave 2

The Mobile WiMAX Forum is determining 2nd phase specifications of Mobile WiMAX (IEEE 802.16e) to ensure compatibility among systems and terminals by different vendors.

Mobile WiMAX Wave 1: Maximum download and upload transmission speeds: 20M/6Mbps

Mobile WiMAX Wave 2: Maximum download and upload transmission speeds: 40M/12Mbps

MIMO and smart antenna was added to Wave 1 (current Mobile WiMAX).

MIMO (Multi Input Multi Output)

Technology that increases the reliability of data signals or transmission speed by simultaneously sending and receiving data by multiple antennas. The 2x2 MIMO system used in ‘Mobile WiMAX wave 2’ allows for twice the maximum transmission speed as SISO (Single Input Single Output).

Smart antenna

Technology that identifies the location of a user by signals sent from the terminal by the base station, and concentrates radio signals on the corresponding user (beamforming).
