Figure 8-9 Link Budget Planning Calculator GPS Calculator

Once the distance is computed follow the steps below for the link budget calculations:

1. Select the radio mode for station 1 and 2.

2. Enter the transmit output power in dBm for station 1 and 2.

3. Enter the antenna Gain in dB for station 1 and 2.

4. Enter the Cable Losses in dB for station 1 and 2.

5. Click the ’Compute Link Budget’ button to calculate the link budget information.

6. The link budget information will be displayed in the following figure.

The link budget information includes the EIRP, Free Space Loss and Theoretical RSSI.

The Receive Sensitivity, Maximum Transmit Power, System Gain and Available Fade Margin at various

Link Speeds are also computed and displayed in a table.

The 1Ideal fade margin for a link is between 10 dB to 20 dB for a stable link base on the environmental

condition of a region.

Fresnel Zone Clearance Required will also be displayed.
