7.1.1. Calculation

Can be used in conjunction with all
RACOM microwave products and
compatible antennas. Available para-
meters 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 accept-
able/marginal/inadequate)
The calculation assumes a clear line of sight and makes no allow-
ance 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).

7.1.2. Alignment

This function behaves like a digital voltmeter with values in dBm (instead of Volts). When activated,
the biggest number on the display (the main value) is RSS dBm value (with 0,1 dBm precision), refreshed
10x per second.
Smaller 4 lines in lower part of the display show 4 key metrics (local RSS and MSE and once the link
is established also remote RSS and remote MSE) and their best values (in right column). Any of those
can be chosen to become the main one (the biggest number on the display), just by taping on it by a
finger.
Additionally the sound can be switched on. Then tones or pulses related to the main value are produced,
with coarse or fine sensitivity (coarse at the beginning, fine for fine tuning). Additionally every 5 seconds
the current value is told in English, so the absolute value of main parameter could be heard even without
looking to the display. The sound can be used with a big advantage in situations, when both hands are
needed and the mobile has to be in the pocket (in such a case Bluetooth ears are the best choice).
