7. RAy Tools app for Mobile devices

RAy Tools is a stand alone application designed to perform link management, is optimised for use on mobile devices with smaller displays and especially in challenging conditions.

RAy Tools supports the following functions:

  • Link Calculation – to calculate or verify the link budget

  • Antenna Alignment – provide measurement of RSS and SNR for fast antenna alignment

  • Link Management – standard web based unit management

7.1. Menu options


        iOS version

        Android version


Can be used in conjunction with all RACOM microwave products and compatible antennas. Available parameters to input that affect link budget are:

  • Modulation

  • Throughput

  • Tx Power

  • Link distance

  • Antenna specifications

Ray Tools calculation outputs are:

  • Free Space Loss (FSL)

  • 1st Fresnel Zone radius

  • RSS

  • Sensitivity

  • Fade margin (shown to be acceptable/marginal/inadequate)


The calculation assumes a clear line of sight and makes no allowance for precipitation. A more accurate calculation can be performed using the tool available on RACOM web pages (see
https://www.racom.eu/eng/products/microwave-link.html#calculation). Precise link calculation should be performed using dedicated tools (e.g. Pathloss).

 Antenna Alignment Tool is accessed using this menu. See Section 5.6.2 Live data for description.
