To calculate the link budget
1. Select your WinLink system product from the dropdown list of products.
2. Select the rate from the dropdown list. The rate defines the air-interface rate in
Mbps. The system operates in TDD mode and has overhead of the air-
interface protocol and therefore the accurate actual throughput is provided in
the ‘Service’ Row and the effective Ethernet throughput is provided in the
‘Ethernet Rate’.
•
Throughput can be decreased as a function of range due to propagation delay.
The remaining fields are completed automatically depending on the product
selected in the product field. Standard FA4800 system parameters are entered
as default. Fields in blue boxes may be edited if non-standard antennas and
cables are used.
The Fade margin is the minimum margin that is required for LOS conditions.
For degraded link conditions, a larger fade margin should be taken into
account.
