UPB Specifications

PCS has introduced a comprehensive line of UPB-based lighting controls, PulseWorx™, which set a new standard for reliable, cost effective lighting control in the home. In addition, PCS has licensed the technology to a number of commercial and residential equipment providers, enabling a standard for reliable powerline control.

PCS' powerline communication technology utilizes a PPM (Pulse Position Modulation) encoding/decoding method. The physical layer method is a very different scheme than the modulated/demodulated RF techniques used by other manufacturers.

A series of pulses are produced in rough synchronization with the main line voltage frequency. The relative position of each pulse may vary over a small range of time or position relative to the previous pulses. Because the data is encoded into these differences in position, the method of modulation is called Pulse Position Modulation or PPM. The function of a UPB transmitter is to produce a series of precisely time pulses that encode the digital information to be transmitted. The function of the UPB receiver is to detect the pulses, determine the positions, separate the pulses from noise and finally produces the decoded data.
