What is C/I?

Also known as[edit]

  • C/I CIR Carrier To Interference ratio / S I R SignalToInterference
  • C / I C I R CarrierToInterference / SIR Signal To Interference


What is C/I[edit]

C/I = Carrier To Interference

C/I or CIR or SIR or S/I is the quotient between the average received modulated carrier power S or C and the average received co-channel interference power I, i.e. cross-talk, from other transmitters than the useful signal.
