Collocation Interference (nearby stations)

The Interference tool calculates only far-field interference.  The Collocation Interference tool  performs calculations of interference situations in sites (locations) with many transmitters and receivers. The following sources of interference are calculated.

  • Intermodulation, 2nd order and selectable odd orders up to the 13th order with up to 13 simultaneous signals
  • IF breakthrough with 1st IF included
  • Image frequency, receiver image considered
  • Harmonics, selectable up to the 13th order
  • Co-channel and adjacent channels interference
  • Receiver blocking

Spectral widening of intermodulation, spurious and harmonic signals is considered. Individual transmitter duty cycle is included and the probability in time for each potentially interfering signal is calculated.
