EIRP

EIRP

Expected RSS and Fade Margin

ExpectedRSS
where:
Site A is the transmitting site
Site B is the receiving site
PathLoss is calculated according to the free space model,
PathLoss
ExpectedFadeM
where Sensitivity is dependent on air-rate.

Min and Max Range

MinRange is the shortest range for which
ExpectedRSS
MaxRange (with Adaptive checked) is the largest range for which
ExpectedRSS
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
ExpectedRSS

Service

The Ethernet and configured TDM trunks throughput is calculated according
to internal product algorithms.

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).
