# RF link budget
# Scope: Logarithmic link budget; gains/losses are dimensionless dB values.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

transmitDbm = 10

receivedDbm := transmitDbm+transmitGainDb+receiveGainDb-pathLossDb-otherLossDb

check link margin target: marginDb >= 10

scenario alternative: transmitDbm = 8
