OFDM FORUM ADDS MEMBERS, TARGETS VEHICLE-TO-VEHICLE COMMUNICATIONS [From ConvergeDigest. And timely.] -----article begins: The OFDM Forum added 11 new members – including 3Com – to its roster, bringing the total number of participating organizations to 56. Among its potential applications, OFDM technology is being considered for use in future automated vehicle-to-vehicle communications. Researchers at the University of California at Berkeley's Partners for Advanced Transit and Highways (PATH) program are currently using IEEE 802.11b wireless technology in vehicles equipped with automated steering, acceleration and braking systems. The vehicles communicate with each other to perform merging maneuvers without human assistance. The researchers have plans to migrate the wireless systems to OFDM in the near future to mitigate multipath issues and provide higher data rates. ofdm-forum.com The OFDM Forum, February 22, 2001 OFDM is a modulation method that encodes and transmits data on multiple high-speed RF signals concurrently. The technology is highly tolerant to noise and multipath interference. In November, The OFDM Forum submitted a physical layer proposal to the IEEE's 802.16.3 subcommittee.. The proposal endorses using OFDM technology in the physical (PHY) layer of fixed wireless access systems below 11 GHz. In September, the Federal Communications Commission (FCC) announced that it does not intend to certify Orthogonal Frequency Division Multiplexing (OFDM) systems for use in the unlicensed 2.4 GHz frequency band in the US. The FCC ruled that OFDM does not fit the definitions of a Direct Sequence Spread Spectrum (DSSS) System, and therefore is outside the intended use of the unlicensed 2.4 GHz frequency band. The ruling affects only OFDM in the unlicensed 2.4 GHz frequency. -----end
