First lets understand what wimax is ......
WiMAX, the Worldwide Interoperability for Microwave Access, is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access. It is based on the IEEE 802.16 standard, which is also called WirelessMAN.
The name WiMAX was created by the WiMAX Forum, which was formed in June 2001 to promote conformance and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL."
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.
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.
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 1: Maximum download and upload transmission speeds: 20M/6Mbps
Mobile WiMAX Wave 2: Maximum download and upload transmission speeds: 40M/12Mbps
