AFE031 Power Line Communication Distance

Other Parts Discussed in Thread: AFE031

I´m designing a Power Line Communication System for home Automation. I would like to know is the AFE031 is suitable for an application where the distance between the transceivers is 5000 m and data rate 9600 baud.

    Hello Mr. Cadena,

    The achievable data rate is heavily dependent on the channel conditions. For the 5km line you mentioned, do you know the characteristics of the noise present on the line? Also, do you know how much attenuation will such line introduce on the PLC signal?

    The paper “Developing robust power line communications (PLC) with G3” has a comparison on the maximum data rates available for different communication standards typically used in utility metering applications.

    http://www.ti.com/webemail/2012/email/MCU-Power-Line-Comm/slay021_pdf_redirect.shtml

    G3 and PRIME standards are supported on our TI Power Line Modem Developer's Kit (TMDSPLCKIT-V3): http://www.ti.com/tool/tmdsplckit-v3

    The best way to find out the package error rate in your application would be to actually connect two modems and run tests under different scenarios (with various loads coneccted to your power line.)

    Hope this helps. Best regards,

    Jose

    Thank you for your response. The nature of the noise over the line is impulsive and White Gaussian due the presence of electrical machinery (air compressors, drilling tools, dimmers) . The average noise´s power is -80dBm.  Attenuation over the line 20 dB.

    We've considered buy two Development Kits C200 to carry out field test to study the performance of the system for our application.

    In order to implement the PLC Modem, We consider use the TMS320F28069PZT microcontroller. If we buy more than 500 microcontrollers, Can you deliver the microcontrollers from factory programmed with our firmware ?

    Hello Mr. Cadena,

    Communication should be possible despite the nature of the noise and attenuation you have seen in your power line. Field test remains the definitive answer to your question, though.

    Unfortunately your question regarding delivery of 500 microcontrollers programmed with your firmware falls outside of my realms of expertise. My suggestions would be to re-post that portion of your question on our C2000 forum (http://e2e.ti.com/support/microcontrollers/c2000/default.aspx) or contact your local TI distributor.

    Hope this helps. Best regards,

    Jose
