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).
