Real-time communication

    UVAX has developed a unique communication platform based on B-PLC (Broadband Power Line Communication), which makes it possible to transmit data at high speed through the electricity grid to receive information in real time.

    UVAX began R&D and manufacturing of B-PLC equipment in 2006. It is currently one of the few global companies with a large number of projects in different industries and extensive experience in B-PLC technology.

    Why PLC?

    • Because it does not require any additional wiring for installation. It uses cities’ existing, underused electricity grids.
    • Because it reaches data transmission speeds of up to 600 Mb/s.
    • Because it makes it possible to create innovative solutions for smart cities.
    • Because it coexists with other technologies: fibre optics, radio, etc.

    The concept of data transmission through power lines is as old as the electricity grid itself. In the early days, signals were sent down the power lines for status reports, to detect faults in the grid, telemetry and even to share information between substations themselves. The constant research and development effort into modulation techniques, encryption and signal injection and processing have now made it possible to achieve excellent levels of speed and reliability.

    Larger packets were first carried on frequencies between 20 kHz and 200 kHz, today known as the IEC61334 standard, using the CENELEC-A-B-C bands. Such transmission, considered narrowband PLC, is capable of transmitting data at a speed of up to 200 kbits/s.

    In 2003, work began on DLC (Distribution Line Carrier) System Technology. This is considered medium-speed narrowband, transmitting at frequencies between 9 kHz and 500 kHz and provides speeds of up to 576 kbits/s. This technology was used as the basis for the PRIME (PoweRline Intelligent Metering Evolution) alliance, made up of several companies in the industry in 2009. It is mainly used for remote management in relation to smart meters.

    Meanwhile, efforts have been made to develop and evolve B-PLC (Broadband Power Line Communication). Now, thanks to more advanced technology in digital systems integration, data transfer speeds of up to 600 mbits/s have been achieved, which will soon rise to 1,000 mb/s. With integration of digital and analogue circuits, new modulation techniques such as OFDM (Orthogonal Frequency Division Multiplexing), digital signal processing and other techniques used for this technology, PLC has reached levels which can compete other communication services in terms of both performance and price.
