For more information about RF range, read our white paper Understanding Range in RF Devices.

  • Understanding how environmental factors can affect range is one of the key aspects to developing a radio frequency (RF) solution. This white paper will provide a high-level overview of the factors that can affect RF range, including hardware selection, environmental factors, frequency ranges, and proper implementation.
