SYSTEM ANALYSIS
Link budget
Account for the complete RF path and compare received power against receiver sensitivity.
Link margin15.0 dBAbove sensitivity
01
Transmitter
Power at the source and transmit antenna gain.
EIRP26.0 dBm
02
Channel
Propagation loss plus cables, connectors, and other losses.
03
Receiver
Receive antenna gain and minimum usable signal level.
EQUATION
Pᵣ = Pₜ + Gₜ − Lpath + Gᵣ − Lmisc
Link margin is received power minus receiver sensitivity. Positive margin means the modeled signal exceeds the minimum usable level.
