optimizing wifi range

  • Hi, this is my first post so hello everyone!

    I'm fairly new to Wi-Fi, so please forgive any dumb questions..

    My main question is: how can I achieve the maximum range with a WiPy. Data rate and power conservation aren't a priority. I can use a standard external antenna on the AP but STA must use internal.

    In this context:

    • is there a practical difference in effective range between the IEEE 802.11 b, g and n protocols? Also, is network.phy_mode([mode]) available on WiPy/LoPy/ESP32? I can try this myself, but still interested in any comments.
    • does channel selection impact on range, or only on data rate? Intuitively, the lower frequency channel will have better range, but is there any real difference across the available bandwidth? Also, what are some good heuristics for optimizing channel selection in code?
    • finally, is WiFi-ah anywhere on the pycom roadmap?


  • Hi @bitrat, I moved your topic to the correct section
