Lucent Technologies yesterday announced prototype chips for mobile devices that implement its multiple input/multiple output (MIMO) wireless technology, called Bell Labs Layered Space-Time (BLAST). In initial lab testing, the chips received data in a 3G mobile network at 19.2 Megabits per second (Mbps). The chips are small enough and consume so little power that they could be used in cell phones or laptop computers. BLAST uses an array of four antennas to exploit interference among multiple signals transmitted at the same frequency. Lucent is working to speed the commercial introduction of the technology by making its family of Flexent® OneBTS™ base stations MIMO-ready.
