Low Latency Power-Line Communication

Pramodya De Alwis

Hey there,

I am looking for a low latency power-line communication solution for home automation. Ideally below 50ms per message sent. Would this be possible using narrowband modems or would I have to move towards broadband? Are there any TI solutions that I can look at?

Cheers,
Pramodya

    Hello Pramodya,

      First, thanks for considering TI for your PLC design.  If you go to the TI Designs page: www.ti.com/general/docs/refdesignsearchresults.tsp , enter Power-Line Communication in the search bar, there are 24 designs available. 

    This one stands out as a possible close match to your description: PLC Lite Communication Module for Smart Home .

    Please let us know which one is closest to your design needs.

    Hi Pramodya, 

    The time to deliver a message will also depend on the message size. We have two G3-PLC standard-based PLC solutions: CENELEC-A band solution with 46 kbps PHY rate and FCC band solution with 250 kbps PHY rate. You can find the solution and TI designs in the links below.

    Assuming 250kbps G3-PLC FCC solution, 1562 byte can be delivered during 50ms. Since this is PHY rate, considering other factors (node contention and protocol overheads), the maximum size would be reduced accordingly. 

    Thanks.
