• Maximum linear input power (used to calculate minimum distance)
• Antenna gain and cable loss for ODU with integrated antenna
• Available Channel Bandwidths
Calculations
EIRP
Expected RSS and Fade Margin
where:
Site A is the transmitting site
Site B is the receiving site
PathLoss is calculated according to the free space model,
where Sensitivity is dependent on air-rate.
Min and Max Range
MinRange is the shortest range for which
per air-rate.
MaxRange (with Adaptive checked) is the largest range for which
, at the highest air-rate for which this relation-
ship is true. In a link with adaptive rate this will be the actual behavior.
MaxRange (for a given air-rate) is the largest range for which
.
Service
The Ethernet throughput is calculated according to internal product algo-
rithms.
Availability
The Service Availability calculation is based on the Vigants Barnett method
which predicts the downtime probability based on a climate factor (C fac-
tor).
