Alcatel-Lucent now has 15 commercial contracts and more than 70 pilots and field trials underway for WiMAX 802.16e-2005.
The Alcatel-Lucent also noted the successfully demonstration – on its commercial equipment – simultaneous use, in a single sector, of two MIMO downlink technologies, space-time block coding (STBC) and spatial multiplexing (SM). MIMO STBC enables the establishment of a more robust WiMAX signal by leveraging spatial diversity, in turn improving the data rate in adverse radio conditions up to 30 percent. MIMO SM increases data rates by sending different signals on each of the two WiMAX base station antennas, doubling throughput.
