1 Calculate the Theoretical Range

  1. Read Achieving Optimum Radio Range. This document describes the fundamental equations used to estimate range and some of the most important factors that impact range.
  2. Calculate line-of-sight (LOS) range using this excel sheet with your radio settings. The excel sheet is described in Achieving Optimum Radio Range.
    1. Output power
    2. Chip and data rate used
    3. Heights of antennas above ground
    4. Operating frequency
  3. Are there any objects between the LOS of the transmitter and the receiver?
    1. If yes, add a suitable absorption material that can represent the object blocking the LOS.
  4. Choose an antenna gain that is realistic for your project.
    1. Achieving 100% efficiency is not possible. Example: Typical efficiency would be – 4 dBi for a good 433 MHz antenna for a handheld product.
