Planning Your Network

FreeWave provides RF Path Studies to establish reliable wireless communications for your IIoT or M2M application.

As manufacturer of wireless data communications equipment, FreeWave has unmatched expertise in wireless data communications. Our extensive experience with RF and wireless communication systems ensure reliable wireless network designs.

Path calculation and testing is used to help design a reliable communication path for your application by optimizing the following:

  • RF Band (900 MHz, 2.4 GHz, Unlicensed and Licensed)
  • Communication Technology (Single Channel, Frequency Hopping Spread Spectrum, Wi-Fi)
  • Repeater systems
  • Antenna / tower heights
  • Antenna type and gain

Our services are used to determine the optimum FreeWave product, antenna height, pattern, gain, and azimuth required at each site. Radio links to and from each location are analyzed and designed for maximum data link efficiency.


The process is simple. Provide us with proposed site GPS data or longitude and latitude coordinates. If you have existing communications infrastructure, you should also provide antenna types and heights, along with gateway, repeater and endpoint coordinates. Please contact us to learn more.

  • This field is for validation purposes and should be left unchanged.
