A WORD ABOUT UWB

摘要

Ultra Wide Band (UWB) is a radio communications technology that can currently transmit data at speeds between AOMbps to 60Mbps and eventually up to 1 Gbps. It is already well known in the computer and video wirelsss space but relatively unknown for audio; Audio-Technica claims SpectraPulse is the first viable commercial audio product to use the technology. UWB transmits ultra-low power radio signals with very short electrical pulses, often in the picosecond (1/1 OOOth of a nanosecond) range, across all radio frequencies at once. UWB receivers translate these short bursts of noise into data by detecting patterns in the pulse sequence sent by the transmitter.
