WinLink 1000
Link Budget Calculator
Figure C-2. Link Budget Screen
Î
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’.
Note
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 WinLink 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.
