UWBLOC positioning system uses a technology based on UWB carrier-free communication principle to achieve positioning. UWBLOC technology uses nanosecond to microsecond non-sinusoidal narrow pulse to transmit data. By transmitting very low power signals over a wide spectrum, UWBLOC can achieve data transmission rates ranging from hundreds of Mbit/s to several Gbit/s in a range of about 300 meters.
